Sony PSP 2000 Slim Internal 2500mAh Battery Mod 

I have a "no experience" question: I just bought an LG battery to use for this mod, but it doesn't have those two long wire-type things sticking out of it (that you bent over and taped down). Do I just solder the wires directly to the + and - contacts on the battery then?

What did you ended up doing?

Oops really delayed reply, youtube didnt notify me of your reply. Yes you would just solder little wires onto the pads marked + and -. Just be quick since the plastic tends to melt.

@@sjm4306 how is it holding up now? I have a 3010 and I have removed the umd drive, I was looking for a battery that would fit perfectly in that spot so I don't need to do much plastic cutting, I never soldered anything, and since I'm Brazil and will be probably importing the battery, I have to be sure it will all work out, was looking for 3k/4k mah batteries, would you care to suggest some? Anyway this could be done with phone batteries (xiaomi) or powerbanks (adapting USB somehow? ) thx!!!!

@@brenobarbosa3489 conseguiu modificar com sucesso? Tô numa nóia gigantesca com esse mod, primeiro tenho q achar a bateria certa, depois cortar plástico, e ainda tenho q aprender a soldar o negócio todo, fico com medo mas ainda sim quero fazer esse mod

Thanks, glad you enjoyed the video.

You could get three battery packs and utilize the space in the old battery as well with a balanced charger module added. I don't think it matters to the board to get even more hours out of it.

Thanks I appreciate the support!

Nope runs like a dream, infact I played some ys yesterday for about 2 hours with no drop in the battery display bars.

what battery did you use and how is it now?

I used a 2500mAh lipo battery I pulled from a battery bank. I made this video years ago and put hundreds and hundreds of hours of play on the battery so it's pretty weak now compared to when I first installed it so it could use a replacement now. Lipos unfortunately have a limited lifespan even if you take care of them.

Other than installing cfw, this is the most useful mod I've done to the psp so far.

Thanks, yeah sometimes I'm too lazy to show the modding process but I figured this would be interesting to document. And rest assured (pun intended), I slept like a log shortly after filming this. Some people count sheep, I hack things ...

Yeah you could totally do that, in the hayday of the psp several manufacturers released external battery packs like you've described.

Glad it helped and it's always good to hear success stories for these mods!

How long hold the battery if you play games?

umd drive is cool tho

Yep funny you should mention it, I made a followup video about noumd.

I'm trying to do a mod like this, but want a larger capacity than 2500 mAh (just because). I did buy a few batteries, but I was an idiot and didn't fully measure as some were WAY too big. I'm working to buy a new battery that will flawlessly fit, and these are my findings on how I'm picking it. Here are the max battery measurements that I'd recommend when looking for a battery As long as it's UNDER all these parameters, then it should fit. With a larger capacity battery (longer length), it does have to meet a stricter measurement (due to the left part). -- Battery thickness (height) I'd say under 7mm, preferred as close to 6mm as possible. I bought a 4,200 mAh battery that was 8.5mm thick, and the UMD door will NOT close. It's sticking out so it's too tall in height. That's why I'd recommend a 6mm. -- For Width from the top to bottom where the UMD was, that area is around a very tight 70mm (probably 68mm). HOWEVER, the left side where the battery normally goes is just under 55mm. So I'd say the max Width should be 50mm (you will have very small room to spare). -- For Length, if you go from the left to the right all the way across, that distance is about 110mm. Now, that would be a very "tight" fit so I'd recommend a max of 105mm to give some room to spare. So, for a recap: My estimated max room to play with when coming up with a battery for the back (if you want to take up all the room): Height: 6mm would be ideal. Not sure if 6.5 or 7.0mm will work. All I know is 8.5mm is way too much. Width (If only using UMD Section): Under 70mm for sure. I'd say 65mm to be safe. Length (using only the UMD Section): This will only give you around 70 to 73mm in length to play with for the UMD section only. Width (using the whole section, from left and UMD): The width is around 54mm. Max should be 50mm to give some wiggle room. Length (using the whole section, from left and UMD): Measures about 110mm across. Estimate a 105mm max to avoid a super tight fit. ======================= The super, TL;DR version, going by Height x Width x Length (maximum range and should fit): For only UMD Section: 6mm x 65mm x 70mm. For whole back section: 6mm x 50mm x 105mm. NOTE: You may have to cut some plastic parts off, especially the section that divides UMD and Battery.

Thanks. I do some of my best work when sleep deprived!

sjm4306 i could use this mod but as of now i got 3 psp 2000 all of em have broken lcd and missing battery , i'll try do this mod and film it once i got the missing parts , keep up the good work mate

Abraham De Santiago From what I remember there was plenty of room in the thickness department, the issue for the battery I had was the width was a tight fit.

firebirdude2 Still works and charges great. I only leave my PSP on the lowest brightness and low to medium speaker volume as I only use it indoors and so far I estimate runtime to be around 12-13 hours running a variety of psx and PSP games off a 64gb sd card in a ms pro duo adapter.

Holy..... DAMN NICE! Someone should spec a battery from other product that happens to fit even better than yours. Because you and I both know LOTS of people are playing off SD/MS and not using the UMD drive. Could you post the exact size of the battery you installed? So we can look for something similar?

I just did this mod with a vita battery( 2210 mah). It fits snug with a small amount of work and I get great battery life. At full charge it lasted me full 7 hours in Chinatown Wars with the brightness at 3 and sound at max. Awesome

Luís Felipe Marconi Thanks for watching. The psp doesn't run directly off the battery, but rather uses a dc dc converter to generate the necessary voltages so being 0.1V off has little to no effect. In fact the 3.7v or 3.8v naming has little bearing since termination voltages for lithium rechargeables are actually around 4.2v. The psp batteries have a small circuit board that also tell the psp what size battery is attached so it can calculate remaining charge so when you do this mod the battery meter icon will no longer be accurate but the low battery warning will still work. I've heard that there is a way to change the reported capacity in some Chinese batteries but have yet to verify that.

Thanks for the fast answer hahaha when my battery starts to die, i will mod mine. Thanks, it was very enlightening

PSP Hud www.psx-place.com/resources/hud-2-02.214/

BronxShots Charging would minisculy be slowed by having two protection boards on. The self discharge would be increased as well. Overall wouldn't hurt anything having two protection circuits cascaded but it won't help anything either.

Hi sorry for the delayed reply, I just got back from an international trip. The closest I could find to the battery bank I used is this one on ebay ebay.us/ARwAqD

​@@sjm4306 TYSM man!

By my measurements the maximum size is around 65mmx73mmx10mm so stay under those dimensions or the door wont shut.

Thank you!

Dimitris Loufakis If the cell inside the original battery were good quality then yes, but since the one I had was absolute crap with a high self discharge it would only drain both cells faster while not in use so I decided I didn't need the extra likely ~500mAh. The original cell was so bad that if I fully charged it and let it sit it would be dead within three days.

That was a very good answer, it completely covered me. Thank you very much

@@sjm4306 es correcto yo conecte en paralelo con una celda china de psp 3000, y me consumia energia en apagado, al quitarla me di cuenta que despues de dias el desgaste era minimo mucho menos.

HatterAndHare Thanks. A ~4000mAh battery will be just fine so long as it fits, just be aware that it will take quite awhile to fully charge (around four times as long as the stock battery). I can't imagine how long that battery would last, but with my 2500mAh battery I am getting upwards of 12 hours.

sjm4306 sweet, thanks for the quick reply. I can totally deal with longer charge times, if it's going to last me all day I may as well charge it overnight! scrolling through the comments section I noticed mention of a timer? I'm not a tech wiz but I assume this is referring to the chip in the battery only accepting charge for the stock size (ie it would only charge to 1200mah if that was the size of the original cell). hoping I've misunderstood and I don't have to do battery gymnastics to get it to fully charge

HatterAndHare The psp will use the full capacity of any battery attached but it uses the size of the stock battery (1200mAh) to calculate the percentage remaining and estimated runtime. In layman's terms the battery meter may not be accurate but the low battery warning which is based off voltage and not estimated capacity will still be fine. Also the first few times you charge it make sure you keep an eye on it for any heating or swelling of the battery just in case.

sjm4306 phew, what a relief. thanks for all your help, and as a final question before I get started on this, do you recommend buying a cheap battery from amazon/ebay to use the chip in that, rather than the chip in my stock battery?

HatterAndHare Yes I would definitely suggest sacrificing a cheap Chinese clone battery before an oem sony one. The clone batteries circuit boards are fine but the internal cell is where they cheap out.

ADMS11984 One of those alligator clip soldering helping hands would've been a godsend but sometimes you just gotta make do with what you have.

great video, I´ll try to mod one of my old batteries, but I think I´ll just glue the new battery on the back of the psp

@@ADMS11984 get a powerbank

I use a battery percentage plugin and when it gets to around 25% I charge it. Because we are using a different capacity cell the built in bar meter is no longer calibrated so I wouldn't trust it.

Thanks for the kind words. I would check the three battery contacts that connect between the battery pcb and the psp. I had a similar issue where the chinese battery I used had loose contacts and would ittermitantly cause symptoms you've described until I bent the fingers on the metal contacts tighter.

Thanks for your response, sjm. I went back in and examined the connections. Turned out that one of the wires from the battery to the PCB was brittle and snapped during examination. It was probably a loose connection. After re-soldering and almost giving up (I made a mess out of the PCB) it is back to normal! Thanks again, sjm. I look forward to finding another interesting project from your channel!

That's awesome, glad you were able to fix it!

sjm4306 is this mod the same on PSP 1000? I wanna try it.

Pretty much, but the method to remove the umd door is probably different. Note I havent done it myself but I dont see why it wouldnt work.

Thanks!

Oh I just meant to fully charge and run down to like 30% a few times, this "cycles" old batteries and gets them working better

@@sjm4306 ooh i get it, thank you ! :)

Thanks! I show a lot of love for modding nintendo systems so I though I would do a video on my psp for once.

sjm4306 Yeah it worked out well

mine is like that too unfortunately

@@renatinhoss I've waited for one more hour and the light indeed goes off. Everything seems to be working fine!

Probably the percent gauge needing to recalibrate after increasing the battery capacity. Give it a few charge cycles to see if it gets better. If not there's a work around on certain battery protection boards to solder pads to tell the psp the new capacity.

adam So long as you are careful soldering the battery it really isn't difficult.

Roman Jr Asidera The chip is for protection, tells the psp the estimated capacity and most importantly is necessary. Without it the psp refuses to boot.

thanks for answering. My original battery have weird problem, even shes full charge, it sudden turn off, and cannot turn on unless you remove the battery and replace again and it will work again and turn off after a while again. that is why im planning not to use the chip cause i think something wrong in that chip

Roman Jr Asidera It sounds like the pins aren't connecting well and when it loses contact the psp shuts off. Either way replacement batteries are cheap to buy just for their circuit boards and you can replace the internal cell with a larger one like I did.

Yeah I guess it's either something wrong with the psp (not likely though if it didn't drain the oem battery) or the battery protection board. I will say though that the psp will drain the battery a bit when put into standby/sleep mode unless you completely shut it off (by holding the power switch for a few seconds till the screen goes black) but if it's completely going flat faster than a month or so while sleeping then it's definitely not normal.

Yep, will work with any model psp

Robin2win14 Nope so long as it fits.

Nicola Usai Thanks for watching!

Battery wasn't from a very high quality powerbank (it was a freebie from a conference) so self discharge was pretty high. I'd estimate letting the fully charged battery sit in a drawer would drain it in a month. However if fully charged and immediately played I got well over 10 hours of runtime on the psp with decent backlight brightness and speaker volume. I didn't time it exactly unfortunately but I'm confident enough in that estimate after a quite few charge/discharge cycles. It's been a few years since this video though and I've moved onto a ps vita as my daily driver so I'm sure the battery in this psp has aged quite badly by now.

@@sjm4306 damn 10 hours runtime is way higher than what I was expecting, do you still recommend doing this mod for the psp? I've always wanted to own one but i am quite concerned about finding good replacement batteries

Absolutely worth it in combination with running cfw and adding a large micro sd card to load games from.

champen22 The psp was designed to be able to use while charging and simply changing the battery wouldn't affect this. The only bit of caution I would advise is after changing the battery, during the first few recharges keep an eye on the psp and every once and awhile touch the back to make sure it isn't getting hot. Once you've put a few recharges in and everything is fine then you can be rest assured that the battery will behave.

sjm4306 Thanks for the answer. That gives good meaning.

It will work with the original battery PCB. Batteries charge via constant current then constant voltage not coulomb counting so it will always fully charge but the caveat is the battery level bar indicator will no longer be accurate (however the low battery warning will still work).

Sweet! thank you so much for the detailed info, I'm gonna do this as soon as my donor battery come thru my mail

Yeah in that case you'd need to get the protection board from the psp street's internal battery.

I believe if you have a hacked psp with custom firmware you can go into the vsh menu and change which memory can be mounted over usb (though you have to be careful as you can potentially brick the psp if you mess with the wrong files).

@@sjm4306 Thanks for answering a question not related to batteries, you are very nice. SUB+

No problems as far as I can tell (maybe the battery may have degraded a tiny bit but it's hard to tell), I just used it over christmas break to replay some ys and it work great.

The watt-hour rating of a battery is simply the battery nominal voltage multiplied by its capacity (so for your nexus battery it'd be 3.8v x 2.1Ah = 7.98Wh). Since you are replacing the psp's stock battery with a higher capacity one then even though the nominal voltage stays the same then of course the Wh rating increases.

The voltage written on the battery is the nominal voltage and not actually what they are charged up to (both terminate at ~4.2V). It's absolutely safe so long as they are properly insulated and use a protection circuit.

If it's in protection mode then you wont see continuity from battery board contact negative and cell negative. What's the cell voltage? If it's too low the protection circuitry may be in precharge trickle which can take a long time to get the voltage up to a level where it'll charge at a regular current.

@@sjm4306 yeah i think you're right cuz when i charge it, It's blinking orange light. I think it's in protection mode. I'll charge it for a several hours. Thanks for helping 😃

The original battery is of questionable origin (the battery was very cheap afterall) and probably very low capacity so I didnt want to risk it swelling or heating up just for a small increase in capacity.

If you buy the raw cells from a reputable seller/site like batteryspace you will get much more bang for your buck.

"To the Interwebs!"

If you are using a used battery that is two years old or more then be aware that it might have lost capacity due to age and use depending on many factors such as temperature, charge/discharge cycles, discharge state, storage conditions, etc. Another thing is have you let the battery now in the psp run till it shuts off and then fully charge? This should calibrate the controller and also I've noticed since putting a 2,500mAh battery inside the psp 1,200mAh one that the psp still thinks it is the smaller capacity one. So I run it for 4 hours and the battery meter shows that it is almost empty but I am able to run it for another 10 or so with only 1 bar left. I've heard about a way of soldering some pads on some chinese battery boards that will tell the psp the correct battery capacity but have yet to confirm this for myself.

thanks for the answer, It may be true of your statement, bcause the weirdness happens on my psp, if I play with 50 or 60% battery left then I leave the psp for several hours, the battery will rise itself up to 95 to 100% (usage back to 2 to 3 hours). WTH this :D I suspect maybe the original 1200mAh circuit boards limit the mAh more, I do not have a spare battery for my tests. If there is a way to remove this limit please let me know, and create a nice video. Thanks.

It should be alright, just tell your son to keep an eye on the temperature around the battery while he is playing just in case it starts getting hot due to the battery shorting. Sounds like the psp just isn't detecting a voltage even though it detects the chip so it's giving a warning. If your son is comfortable, the safest thing would be to open it and wrap tape around the disconnected battery wires.

Thanks. Will ask him to do the same. He is ten years, never had the chance to play snes,gameboys but he likes them now. Thanks to your mod, my old psp got a new life. Hopefully I will resolder everything. Appreciate ur help.

The original battery protection board is used and the psp regulates the battery so this is no more dangerous than an oem battery so long as you insulate exposed wiring before closing it up.

Lipo (though either will work, generally there's more of a variety of lipo sizes so it's easier to find one in the right size)

@@sjm4306 thanks man this is really helpful, now i have a bigger range than what i was looking at heh. I hope you make more PSP vids in the future :)

When you say you bought a new one do you mean a new battery? The symptoms you are describing kind of sounds like a dead or damaged battery.

@@sjm4306 yes a battery. i went to the technician and he said its the problem of all the psp 3000 models and that, so even if i buy a new battery again it would still not work. i mean, that isn't true right? thanks for replying by the way. nice channel got the notifications on.

I don't really understand what the technician means when he said its a problem with all 3000 models (I have a 3000 and it charges the battery perfectly). One thing to check that gave me a similar issue once is there are three contacts between the psp and battery: positive, battery data and negative. On one of my psps that stopped charging a good battery the middle contact in the battery was loose so I had to carefully open it and bend the metal fingers inwards a bit so it made better contact. It started working after that, since the psp needs to read the data from the battery to even charge or use it (sony's attempt I guess to prevent aftermarket batteries or to have different capacities which the psp could read to estimate remaining life).

sjm4306 i think what he meant is 3000 models has battery issues like that. thanks for the quick response. anyways do you have plans in your mind in making a portable ps2?

I've always wanted to make a portable ps2. I'd definitely want to get an early 7xxx model though that can be wired to an ide hdd so I could remove the optical drive completely.

If you are running custom firmware just disable the switch in the vsh menu.

@@sjm4306 which one is it? I am new to this

Here's a tutorial to install the cfw to hack the psp first off: wololo.net/installing-pro-cfw-on-a-psp-3000-psp-brite/ Then you'll have to install and enable a plugin called noUMD (a google search will get you the file and I believe I even made a quick follow up video after this one to show generally how to use the plugin). In general to access the vsh menu I believe from the home menu you press either start or select (I forget which one, haven't used my psps in awhile since I upgraded to a vita). From there you can select installed plugins and turn them on or off.

@@sjm4306 i already got cfw. Im just missing the noumd. Cheers mate

If you have a multimeter check with the beep mode (with no battery attached) or visually to make sure the pads are electrically connected. Pretty sure if they have the same label they are connected though.

Help I'm charging a clone battery , after plugged the orange light comes on for a bit and minute later turns green then later will shutdown along with psp. When I replugged the psp same thing happens. Battery information says external, shows 3 bar battery icon on the top right. however if I try to play a game then check the icon with the home button, the battery icon is flashing (appear , disappear) this time it is the battery that is filling animation.

This is a common problem. The three metal contacts that connect the battery to the psp are loose. You need to very carefully bend the contact fingers on the battery pcb inwards so they make better connections. I would advise you desolder the battery first though so you dont accidentally risk shorting something.

I would used wire no thinner than about 18-20 gauge.

@@sjm4306 Yes! :D thank you for the reply, I can't start doing this because I have no idea of what wire to use. :)

Another question can you clarify what dimmension of the battery needed? :) the dimmesions on the description doesn't have label of (w×h×thickness). :)

65mm Width, 73mm Length, 10mm Thickness

Thank you sir again for the reply. :)

The disc mechanism definitely needs to be removed to fit the battery I cboose and while you may be able to get it out without taking out the door it'll be more difficult. Of course once the battery is installed the door can be reassembled and the mod looks stock from the outside.

what Xiaomi battery exactly? can you give us a link please? thanks a lot!

What battery dpes you mean? Give pls name

Make sure the contacts between the battery protection pcb and the psp are making good contact. I found the cheap chinese replacement battery contacts are pretty loose and may need to be bent slightly to make better contact.

I would check your wiring and the pcb pin connections to the psp. Also if you used a chinese battery some of the boards have solder links to change the capacity reported to the psp.

I've looted the battery board from original PSP 2000 1200mha battery made by Sony. It's weird that when I mute its speaker then there's no problem. But when I turn the speaker on, it eventually goes off in any time. I couldn't solder the wires to the battery because the solder don't really stick to the board. The solder makes droplet shape and never stick to the board.

It'd be a lot easier to figure out if you could link a picture of your wiring.

i found it in someone webste "the labels where you can solder are B+ and B-, sometime it is called LD1 and LD2 but LD1 is the positive side generally." www.instructables.com/id/How-to-Fix-a-Psp-Battery/

One of the wires/connector spade terminals isn't contacting reliably. I had this exact problem and it turned out the middle contact between the psp and the battery was very loose so the psp couldn't detect the battery properly. Carefully triple check all points of contact and you will find the weak point.

I checked the pcb and the negative one is loose, can you tell me what did you use to tighten the spade terminals.

I used a needle to very carefully bend both sides of the metal fingers on the female battery connector inwards (just be super careful no to accidentally short anything). Don't overdo it, just enough to give a firm grasp of the psp battery contacts on the pcb.

Thanks, I'll unsolder the wires to be safe.

Also, what was the powerbank that you gutted? :P

Robin2win14 Yep this will work for any psp model so long as the battery physically fits. I don't know the battery bank specifics as I got it as a gift from a company I was visiting during some testing for work.

Alright no worries I'll make sure I stay under the size limit. Thanks for a great and detailed video.

Kartowl Salad If it is a semi-modern phone then it's either a lithium ion or lithium polymer so either way the termination voltage will be 4.1-4.2v irrespective of what the label says. It will not harm the psp either way since the input goes to a switching converter regulator. It would be really silly if Sony designed the psp to self destruct just because your battery is 0.2v higher than the nominal voltage.

sjm4306 its from I guess 2015, redmi note 3, so that means the battery stops working at these voltages you mentioned?

Kartowl Salad All lithium rechargeables when fully charged are around 4.2v and considered dead when they drop below around 3v. If the battery voltage gets charged/discharged beyond this range you get an increased risk of battery fires/venting like you see in the news.

and how about dropping the output voltage with a Trim Pot? it still could be charged normally because they charge with 5v input am I right? because I really want to use this battery because of its high capacity, or can I just use it with its 4.4 volts max output in the PSP without lowering the voltage, because the PSP takes 5v in for charge and to keep it on without a battery.

Kartowl Salad There must be some sort of mislabelling then as no lithium rechargeable battery chemistry exists that has a termination voltage of 4.4V (in fact charging currently available batteries to that high will likely make them swell, burst, and ingnite). Just wire it as I've shown in the video and the psp charging circuitry will safely charge it to 4.2V. No complicated inefficient stepping down or anything else to worry about.

I didnt trust the original battery as it was a dirt cheap impulse buy off ebay. I'd much rather have a solid 2500mAh battery than a 2500mAh plus possibly 300mAh battery that may or may not swell or catch fire.

okay. :) I subscribed to you, I am also a gamer and computer engineer. :) I like your content

Andrei Passioukov I'll have to check that and get back to you.

It appears that yours doesnt have that (judging from the second you show the back side of the PCB) but there are D, G, C, R pads on the front... here is a picture of ones with A, B , C - i.imgur.com/SaPe7Bg.png . Supposedly then the capacity etc will show properly.... also if using a legit SONY donor board from a non working sony battery do you know if desoldering the PCB resets any eeprom counters on there? Because it has been shown that official batteries do count number of cycles, so if reusing same board for batteries over the years and counters get into thousands it will be wildly wrong estimates on battery power.... but by definition eeprom is non volatile... so probably not? So it may actually be way better to use Chinese donor boards where we can set our capacity. lastly... the protection circuitry is not on the PCB right? Its in the Li-po cell itself? When using these bought Lipo cells the protection circuitry can stay intact?

Andrei Passioukov Yeah mine has the ABC pads just under the chip and above the battery terminal. I might just solder one and see what it does. Didn't know OEM Sony batteries kept track of charge cycles but I guess that makes sense. Also protection is handled by the board and the cell is raw.

So if using another cell, most of them have built in protection in the cell (you can see wires going to a small chip and then from chip to the battery). Then you would have double protection? One in the PSP donor board, and one in the battery? Can that cause issues? For example this one - imgur.com/a/1CNcT As far as those pads, yeah I think none being shorted is default 1200Mah or whatever, then by shorting additional ones you add to that number, like 1200mAh + 1000mAh etc... some of these chinese boards have a diagram on the back of the PCB with the values.

Andrei Passioukov Having double protection shouldn't really make a difference, just one would happen to trip before the other and the standby drain might be slightly more. As for the ABC pads, I am almost absolutely sure all the clone batteries use the same exact chip with the same firmware so if we can find the pic with the settings we could use it for all boards.

I would have done that if the battery cell that came in the original battery was reliable. This one was from China and of questionable quality (another one of these batteries I bought started to swell after a few months of use) so omitting it increased reliability as a whole.

Hasn't bloated yet (thank god), but runtime is only probably half of what it was when I made the video. The secret to preventing batteries from bloating is to partially charge them a bit every few months even if you don't use them (up to ~80%). They bloat because they deplete too far and when charged up from completely dead after a long time a side reaction that consumes the electrolyte to produce hydrogen gas occurs, permanently damaging the cell.

@@sjm4306 Thanks for the update and the tip :)

Ata Yurt Yep, will work with any battery that the psp recognizes.

Thanks a lot! Cheers

It's usually marked, but there are usually other telltale signs like the negative is usually on a large ground plane and any connection to nearby polarized caps can be used to deduce polarity. The easiest way though is if the battery is still attached to just measure the voltage with a multimeter to find the polarity.

@@sjm4306 um... Slight problem with that. The battery didn't explode per se, but it did expand to an amount that makes it clear the cell is dead. I looked at the cell and there is a positive label, but no negative label. Im making an assumption that the negative lead is the one further from the positive marker, I'm just not entirely sure and don't want to fry the board.

For the connection between psp and battery module, yes the negative is the far opposite pad from the positive and the middle is the digital battery identifier signal.

Wallkar Wallkar I haven't had any major problems besides the graphic indicator being off but then again I use a vsh plugin that displays a voltage and percentage overlay in the corner so I just use that to gauge remaining battery life. Since this video a commenter pointed out that the pads labelled A, B, and C are used to tell the psp different capacities and by referencing a chart I was able to short the correct pads to tell the psp I have a ~2500mAh battery.

Просто руки жопы, поставил на 2к, отлично работает,не выключается, работает больше,7 часов игры, показатель может врать лишь и все

Yep, still use it. Maybe battery life has decreased a bit but I put a good number of hours into replaying ys over xmas break and it held up just fine.

Yes, but make sure the voltages are the same before soldering them in parallel or one will try to rapidly charge the other and could ignite.

@@sjm4306 Thank you. Wasn't sure if the battery control circuitry could handle that.

alphanate75 Thanks. Unfortunately the link is a general affiliate link and not one for the batteries. It is difficult linking to a specific battery because of how quickly stock changes from these Chinese sellers and there is often no easy way to search by battery size other than reading listing descriptions to find out dimensions. I get inundated with requests to constantly update links. So instead I posted the dimensions of the umd bay so that it would be easy enough to check if a battery would fit. I wish I could link the exact battery but I know as soon as I do within a week it would be sold out and I'd be back to square one.

Yep

This mod will work on psp 1000, 2000 and 3000. As for the specific battery to use you will have to search ebay and use the dimensions I posted in the description to find one that will fit.

DRod VFX Yes any lipo or li-ion battery will work so long as it fits.

sjm4306 it's a li-ion battery. So the original charger for psp.. Would charge the battery?

DRod VFX Yep, as far as the psp knows nothing has changed.
