Capacity is not everything. You need to take Energy storage in to consideration if you want to compare two different Cell chemistries. In that case: NiMh: 2 x 0.75Ah x 1.2V: 1.8Wh Li-Ion: 0.25Ah x 3.7V: 0.925Wh Also you have to take charge and discharge losses in to account, Li-Ion cells are at something like 99%, I'm not sure how high the losses are for NiMh, but they are way higher. But I agree, it's a stupid idea in that case. Also there is no discharge protection, so that cell will probably die, because the remote probably still works at 1.8V or even lower, which will quickly kill the Li-Ion cell. With some devices, it does make sense (old NiMh Battery powered drill is a prime example were it DOES make sense). But for such lowpower devices, it really doesn't.
Did you know they make rechargeable AA and AAA batteries that work great in things like remote controls? You can even have two of them changing while you use two other ones in the remote and just switch them as needed. Genius is not finding a more complicated solution to an simple problem - it is finding a simple solution to a complex problem.
A genius would add a coil to a capacitor and have a magnet that moved freely within the coil. A quick shake would charge the capacitor and provide enough power to use the remote. But don't let anybody know about this...
I totally agree and do that myself, but there is one advantage to being able to recharge the battery without having to swap out for freshly recharged ones. Invariably after weeks of use, the batteries conk out at a critical moment when I'm using the remote, and this would allow me to plug in to the phone charger I always have handy at my TV chair and keep going without getting up or interrupting my watching. After all, the whole point of a remote control is to avoid getting up out of your chair, right? 😉 I actually have one old universal remote that has a (gasp!) replaceable rechargeable Li-Ion battery and a charging dock, but most don't. None of my Logitech Harmony remotes are rechargeable, and with their LCD displays they run through batteries much quicker than most remotes. I think I'll need a bigger battery than the one used in this video, though.
@@awo1fman Your remotes batteries never fail instantly to the extent where you would need to get up and get new batteries immediately. Failing batteries will take many weeks to completely stop working. The trick to keeping them alive for longer is knowing that the batteries and the contacts will oxidise over time. When they start to lose power, simply shake the remote, which will slightly move the batteries, which will clean a little bit of the oxide from the contacts allowing the reduced power to be enough, as you're reducing the resistance in the circuit. After a few weeks this will become less effective, but you can then open the remote and give the batteries a half rotation and this will improve the contact and you'll get a few more weeks of power, in which time you can replace at your leisure and convenience. I once got 3 extra months out of some failing remotes batteries.
They're already out. I think it's called Nickel cadmium. Something like that. I had them when I had RC cars back in the day. Came with a charger but the charger didn't keep the charger like what's out now.
@@pedrorodriguez8942 Yes they were the ones like on the old Dennis the menace show when Mr Wilson kept trying to figure out why his remote wouldn't work. They were huge and made a loud click noise changing the channel and had to wait like 10 seconds for the signal to catch up with the TV 😂
Take a walk through a factory and you’ll notice that they’re fairly complicated operations. This guy came up with a great idea that manufacturing companies should implement. The issue is that the battery companies probably have a stake in the controller/battery powered industry 🤷🏾♂️ Why phase yourself out of a market? If batteries aren’t included with the device, I’d bet that a deal couldn’t be made with the battery company to supply batteries to ship with the device. Just my 2 cents.
@@riffdex _Surely_ he could have disassembled a cordless drill, used the gearbox and motor as a generator, rigged it up to a stationary bike, and used _that_ to power his remote control? Rube Goldberg is alive and well in the Third World -- and he's getting by via YooToob monetization payments!
a couple of rechargeable AAA will require you to take them out every time you need to charge ... but this silly idea allows you to just plug in your phone charger
Lithium batteries have a charge and discharge amperage rating, and the charging circuitry is ideally matched so as not to exceed capacity and cause a fire. This video recommends substituting a charge circuit for a battery that is likely well over the capacity of the recommended battery being used (as no specifications were given for the original battery but it is obviously physically much larger).
shut up and make a video ya nerd. it pointless anyway, why not just use rechargeable batteries in the first place. jimdavis blah blah blah i know everything and want to warn you of the dangers, eh let the low make H/S mistakes thats the joy of life. stop spoiling fun for others
@@CraigAHaskell Yes, I'm aware of petty much all battery chemistry voltages, so when I saw "ORIGINAL" battery voltages, I figured he meant the batteries they come with, alkaline batteries, which I'm sure you know can be as high as 1.6 Volts, but are pretty much dead at 1.2V. So no biggy, just a misunderstanding. I use LiPo battery's with my Radio Control Aircraft. Using rechargables on a remote control is actually a hassle and a waste of energy, since a set of alkalines can last 2 years. But I bet you know that too. : )
And there's me thinking that he'd somehow managed to channel 'thought' to power the remote. Instead.. " I think I'll use a more expensive Battery to replace a cheaper one" - Einstein would be proud of this..
Would have been much better to store the cell up higher in the remote and enclose the little charge board completely inside the compartment. Just open to charge.
Living in your home ,must be like living in an ideal home exhibition supplement . Worrying over scratching furniture or the odd snag in fabric, you big girls blouse .
@@maskedavenger2578 So, my critique of his design, saying he should have taken a moment to consider making it better, makes you judgemental about me and my home? That's interesting. Are you going to point out the other people who've mentioned the voltage of the rechargeable battery being higher than what the remote is designed for, possibly causing it to fail sooner? Perhaps I should have phrased my design comment differently, but I'd hardly call this a "genius" idea. It does a good job of showing an idea, but hopefully so people can learn from it and do a better job. Read the other comments and see, people are doing just that.
@@bobblum5973I don’t know who is worse him for fussing around with a controller ,that only needs a battery every blue moon ,or you fussing about over possible scratches or fabric pulls in furniture ,you both sound a right pair of molls .
@@maskedavenger2578 spoken like a single guy, using a milk crate as a coffee table. While I appreciate the idea, I’ll just replace the $1 batteries every 2 years.
@@EnriqueThiele My couch ends up swallowing my remotes. I have to fight the beast to get it back before it evolves into a monster that then tries swallowing my dogs.
Ours outlast the remotes... those things grow legs and feet and get up and walk off in our house. Only reason the TV's don't is because they are typically mounted up on the wall, too high for our 8 year old to do anything to them. The ones that haven't been before have ended up in our sub basement, his closet, our basement hidden under a table while he was suppose to be cleaning up a huge mess he made... so, yea... I feel ya!
This an excellent idea if you have NO money & are unemployed & have all the time in the world & you live in the middle of nowhere & your only local shop has never even heard of the word Battery.
If you're going to put a cord on it just use a 3v AC/DC adapter... And it will keep the remote from getting lost... Can always glue it to the table too
Pro tip: Test the circuit first before making it incredibly difficult to disassemble by gluing it all together. Or just use rechargable batteries and avoid this whole mess.
Yup I just got 4 lithium AAA 1200.mAh batteries and charger for $10 ....uses any 5 volt transformer .... since my Buzz TV remote uses batteries fast (every 3-4 weeks) now instead of replacing I (R&R) Remove & Recharge batteries instead.....gonna do the same with my AA toothbrush batt's since the same charger will recharge them
At first sight, one might think that the idea is of the same caliber as replacing the television with a large exterior window, but in fact, no! It can be a kind of training challenge because there are already rechargeable batteries! When you install wireless charging on the remote control and wireless charger on a side (or bedside) table, I definitely give you a thumbs up !
I use semi depleted batteries in my tv’s remote. They no longer work in flashlights or other electronics, but still have enough juice to work in your tv remote. Check it out.
And the best bit is that you leave it on charge plugged into where ever your charger is and you can always find it!! Brilliant. No more hunt the remote! And further more you can put the charger next to your TV seat and so don't have to argue who can have it. You are in control! Genius! Why don't they make them like this when they sell the tele?
I plug my microwave into my neighbors outside outlet. Now it doesn't cost me anything to cook my oatmeal in the morning. The only problem their house is 600 yards away from mine, so I had to buy a $800 heavy duty extension cord. Then I bought a $50,000 backhoe to dig a trench so I could bury the cable. That way they would not see the cable. Now that I think about it. I could have saved $52,800 and used my own outlet. I guess sometimes things can get a little complicated.
Because it is useless hack. Alkaline batteries in remote would last 2+ years easily. The time and effort to replace batteries in remote is too low. Same with clocks as most clock batteries last 2+ years. These kind of rechargeable batteries are needed only in intensive appliances like cameras, speakers etc
You could always use rechargeable batteries . You just changed the format of how it was charging and what kind of batteries it took to operate the remote.
Yes, you can have two in the remote and change them out if or when they go flat, two minute job and you can use the remote again , with this you have to find a power bank or if you do not have one you have to plug it into an outlet and wait for it to charge . Dumbest idea ever
In some languages rechargeable batteries are not called "batteries" e.g. some use word like "accumulator". In Polish, for example, for "battery" we call the one that is not rechargeable.
They should design a tv with buttons on it that change the channel and control the volume etc, eliminate the remote all together. That, is a genius idea.
Guest: "Oh, what happened to your remote?" Unemployed electrician: "I modified it so I don't have to change the b.. " Guest feat Skrillex: "CALL 911 NOOW!!"
A 1s lipo is running at a max of 4.2v fully charged. So You're running at a max of 1.2v over. I highly doubt it's going to hurt anything. It might prematurely kill the electronics, but honestly, I doubt it. Electronics are usually rated at a couple volt give or take, so it'll work while the batteries are draining. I think this is a pretty good idea. I would just make it cleaner, and drill a hole in the bottom and hide everything.
Nice idea, but it needs a little tweaking with the terminal sticking out. The control needs a new body design, cause that one gets dropped and ...c'est la vie "its broken".
Great concept for any device that uses 3-4 V, add the longest capacity (mAh) lithium flat possible with a charge protection circuit (like in device he dismantled) and USB recharge very convenient. I've been using rechargeable NiMH Batts for years in some products (headphones, smart deadbolts, flashlights, etc), last almost as long as alkaline (most devices), less likely to leak. (Panasonic Eneloop #1) But they only max out 1.3-1.4 V freshly charged), not enuff V for some products, either to work properly or show accurate %charge left. Lithium rechargeables provide full 1.5+ V , last moderate duration, then nothing (per design, protect lithium cells), but still $$$ and higher failure rate.
I've done the same, but de-solder the USB output off that board to make it way smaller, and you could probably fit it all under the unmodified battery cover. The just remove the cover for charging. But I just buy the boards that are way smaller and are usually under $1.
Honestly, it is kind of a cool idea, I mean who doesn't secretly enjoy plugging things in to charge. He did do something which I would not advise, which was use the battery wires as his output wires. Instead, he should have used the output from the big USB port. This is safer as the charging voltage will not damage the circuit board
I put a 50 watt solar panel in my front window and ran a wire from that to the remote , so every night while I sleep it recharges the remote and the batteries seem to always work without even having to change them
The traditional batteries last way longer than rechargeable ones especially in remote controls that don't take a lot of energy. the rechargeable battery will also loose some charge over time without using it so not worth the hassle, also considering the fact that you will need to put the remote on charge in this case and wait for it but with replaceable batteries you can just put new ones and they will last for at least 1 year
I bought some cheap solar garden lights from the dollar store and discovered that their batteries were AA size. I bought a butt load more of them and use the batteries in other various low power items. Once they run out of juice, I just put them back into the solar lamps and set them outside.
I personally like this idea. And anyone can get free electricity you just need to use your head it won’t B high volts but it could recharge a 3.7 battery!
@max marrero A remote uses only 5-10mA current and that too only when buttons are pressed. So, a typical alkaline battery in a TV remote will last 2 years easily
If the battery he took the pack from and the flat pack battery that he used are different chemistries, voltages, and amperages, than that battery management board might not stop the battery charge/discharge and the thing might start a fire.
Rechargeable lithium batteries already come in AA and AAA sizes already. For a remote, a super capacitor that can be recharged with shaking is a better option though, since you never need to charge or replace the super capacitor.
I can't see the point, AA/AAA nimh batteries are already inherently a suitable voltage, and readily available including high quality ones like eneloop. The extra bit of charge lithium can hold is pretty meaningless for something that uses a tiny amount of power like most remotes.
Not too long ago I figured out how to transplant the guts of a generic USB SNES controller and put them in a high end SNES controller shell to replace a defective board for minimal cost. Even recorded it for a video
By the way they sell rechargeable AA batteries that can be recharged to go in remotes. If you don’t have a charger for the batteries use an outdoor solar light to charge the battery during the day. Once night falls and the light turns on take it out and put it in the remote😊hope this helps 👊🏾
@@lastotallyawesomebleach204 😃 I like to experiment with different electronics and gadgets,light you name it lol I destroy things on purpose to test the durability. 43 years old and I’m still a big kid😂😂😂
I've been doing this type of mods for many of my appliances that run on batteries. Instead of taking apart a power bank, a much cheaper solution is to buy a lithium battery charging circuit with a built in usb port for less than a dollar (10 for $7). Another nice addition is to use those magnetic USB plugs so the remote will snap to the charging cable when you're done, and you never need to manually plug any cables in.
I started using the magnetic connectors. Worked fine for a couple of months. One by one, my devices would no longer charge. I went back to plug in connectors with no issues.
Like how often do you change remote batteries... once per year? They discharge naturally faster than the remote discharges them. Fitting a small solar panel (like on a solar powered calculator) to keep the battery floating would have been a better idea. Then you would never need to open the battery compartment ever again!
@Digital Sat Pro Charging voltage could be up to 5.2V, Lithium battery terminal voltage can be up to 4.2V. The remote control run on 3V(1.5+1.5). Hope this won't destroy the panel of the remote control from overvoltage. A resistor should be placed between the postive of lithium cell and the positive terminals of the remote board to drop the voltage by ~1.5V. If the remote consumes 0.1A current, R=V/I Resistance=1.5/0.1=15ohms. Use ~15 ohm resistor
Your actually right over time there's a little chip in there that will heat up and it'll stop working all together and then you'll weigh the options that it was better just to switch out the batteries then to destroy the remote all together. Been there you have to put in one of those little things they called resistors I think in order for it not to destroy the remote
Very good he actually knows ohms law now you need to know that ,bad boys rape our young girls but violet gives willingly, get some now. And did you know that pac man was a reformed ohm eater ?
Those rechargeable batteries I bought did the same thing and I didn't have to re-engineer my controller. But good for you showing an alternative and creative way. Thanks mate!
I also made a same thing for my Smart TV air mouse remote. In fact, LiPo battery will drain faster than an Alkaline battery in idle / standby mode because it will self-discharge about 5 to 10% / month meanwhile Alkaline is only lost 2-3%/year.
Doing a project like this it's always good to do an operational check prior to securing everything. Had the battery been bad or the charger wasn't able to charge the battery (for example, an internal protection found the wrong voltage from the battery and refused to charge the battery) he would have to do a complete disassembly to fix it.
You guys think the OP didn't test this before filming it? That remote had been disassembled prior to recording. If you have ever opened up any electronics you would have known that.
If you ever do have to take apart a hot glued mess, remember that alcohol type spirits help loosen those bonds. :) Ethyl acetate, ethanol, isopropanol for example.
You can re-use disposable e-cig batteries, with those li-ion usb chargers available for a couple of dollars each. At least you'll save a power bank, and avoid disposing of a good battery.
I doubt that you would need to charge this thing more than once every 4/5 years so cant see the impact on your energy bill, unless you are talking about the energy that the soldering iron and glue gun uses
@@dantronics1682 There is only impact on our stupidity to watch this video. The batteries on remote controls I replace every 5-7 years!!! And they are so cheap ...
I've been used rechargeable batteries for more than twenty years and last time I bought a pair was like 5 years ago. Even the alkalines that came with controls last years
@@tiffanyfrank3654 sorry, i didn't talk about alkalines no way you can recharged them, I meant that the rechargeable batteries last many years and you can be trusted
This doesn't "Say goodbye" to remote control batteries, it replaces them with a rechargeable battery, which could be achieved by putting two rechargeable batteries in the remote control instead.
None of the replacement batteries ever seem to last as long as the funky Japanese or Chinese batteries that come with the device! Kinda makes you wonder 🤔 can't I just get a case of the funky ones??? They would probably out last me!! Lol 😆 🤣 😂
Good job! I think this is to tell the manufacturer's that they should change their batteries replacement system, and rather manufacture rechargeable remote controls
Yes, replacing dead batteries in a remote control is such a daunting task. If this is a “genius idea,” then I’ve been using the word “genius” incorrectly for my entire life.
Looked like it did the same thing in the beginning as it did in the end. So take out the batteries so you can solder in a rechargeable battery…now I have to find that damn cable in the dark again..
