*This battery reconditioning program exceeded my presumptions. It worked on any drill battery, several AA and AAA batteries, **batery.repair** and any camera battery. The steps are simple and the act itself is exciting to do. No matter what type of battery you`ve got, it is sure to function again!*
MSP Redgrave They make the core of most computers. True, they almost never sponsor because either you like it or not your computer most likely has intel in it... intel or amd
***** you can dim down the light on the controller to help improve battery life. Even on the lowest setting its still very bright. And making it shut off after ten min for long hours of netflix sessions helps too. But the controller lasts a long time for long gaming sessions on a full charge
*Graphene!* Please make an episode about whats stopping it!? Is it just a myth? Its been over a decade since its (re)discovered, and we all heard about super-batteries, insane water filters,..even space elevators, but yet, not a single graphene product is yet produced.
the positive to negative concept is called conventional current, basically when the first scientists like Volta discovered electricity they didn't understand it properly and deduced the +ve to -ve theory; these days even though we know better scientists and engineers are too stubborn to change their ways so they just refer to it as conventional current since its not the true current but more like something that's the convention
+sadman hoque It really isn't a problem untill you switch from big systems to electronic systems where you must be very careful to know what an electrical current (the direction) actualy is :D
+100Hasake electrons are also attracted to other atoms that have free space for another electron. The negative side of the battery is like an overpopulated town of electrons that all want to find open housing so they move over to the positive side that has plenty of rooms available. you are right about negative electrons repelling each other, the same is true for positive ones. that is why when you rub a balloon on your head your hair stands on end and spread out. the charge of the atoms in your hair are trying to avoid you and each other.
ph stands for the potential of hydrogen, not, the power of hydrogen. its a reference to the function and quantity of the hydrogen ion not the "power" of it
@@IJoeAceJRI AA sized li-ion batteries are called 14500, but since their voltage i much higher (4.2 V) they cannot directly replace normal AA batteries (1.5 V). 18650 are larger li-ion batteries, which is 18 mm. in diameter, and 65.0 mm. in length (therefore the name 18650).
When I was a kid I thought maybe we could recharge batteries by plugging them But it didn't worked Then I had a DC motor I was playing with it using batteries I thought maybe plug into the socket and it will be faster and more fun Luckily I was a kid so was too short So I had to get a chair Put the motor on fridge and then went down the chair and switched on And boom Fridge got black from above
Here is a more simple explanation for batteries. The electrons in the anode want to go to the cathode (positive side with less electrons), but they are blocked by a barrier. So, they are forced to go through the circuit. Here's a analogy. Let's say you want to go to a room, but there is a wall. Then, a door opens. You can get to that room, but that means you will have to run the distance of the circuit, which slows you down, but you finally get to the room.
The lithium button battery shown in the "high drain" example (3:34) is a computer "CMOS" battery. It maintains data stored the computer's internal memory while the computer is turned off, such as the date and time. This is actually an extreme "low drain" example. That tiny battery is not rechargeable and lasts for many years. The rechargeable battery that powers the computer while the computer is being used is a "high drain" example, but that's not what's shown in the video.
A dry cell alkaline battery is charged because the battery was created with chemicals that hold a charge. Once that initial charge is spent the battery loses a huge amount of efficiency. A typical alkaline battery can omly be recharged a few times. NiCa batteries are easier to recharge and hold weak charges for extended periods of time. Nickel metal hydride batteries are commonly used now and can be recharged but will not hold a charge as long after being recharged and left to sit unused for extended periods of time. Lithium ion batteries are not considered efficient but can be recharged easily, hold a charge for extended periods after being recharged and left unused and are smaller and lighter. Super capacitors are the possible future of battery tech able to hold a charge for extended periods be small, light and recharge extremely quickly. This is a technology I hypothesized would be needed to power a "cloud freighter". Cloud freighters are very large air barges capable of ferrying hundreds of thousands of tons of cargo across oceans in a few hours instead of a few days.
I love DNews. Until I see you guys doing a video on a topic I actually know something about and then realize how sloppy this video is. If you're funded by Intel, please take the time to at least run your script by an expert. I'm sure there are plenty of people on the internet who're willing to look over it for you. Here are the bigger corrections: The battery is made of an anode, *electrolyte* (not electrode), and cathode. In a battery (galvanic cell), the anode provides electrons to the *circuit* (not the electrolyte) and the cathode takes electrons from the circuit. You can get Lithium AA cells like the ones Energizer makes, which has an organic electrolyte and is not an alkaline cell. An alkaline battery has an alkaline electrolyte, not an acidic electrolyte. (Come on! It's in the name!) Hydrogen is actually generated in all aqueous cells during charging, but Ni-MH is able to scavenge it to slow down the pressure increase. You don't see AA sized Li-ion batteries because the voltage is different. This is because the chemistry dictates the voltage of a cell. It has nothing to do with how expensive it is. You can get cylindrical Li-ion batteries (18650). Lithium is not expensive, but the cobalt in Li-ion batteries are. Ni-Cd is basically out of use because it uses Cd, while Ni-MH is getting phased out due to cheap Li-ion. When was the last time you saw a battery like the Ni-Cd battery shown in the video? That's obselete. Cameras have generally used Li-ion for like, the last 10 years.
I don’t know enough about this topic to be sure but you seem to know what you’re talking about. I did not like this video or find it very informative myself.
God! You totally dropped the ball on educating people about NiMH batteries! They perform better than Alkalines (except self discharge for applications like smoke detectors) and are cheaper, safer (don't corrode electronics), store more energy, can deliver more energy, and are "greener" Please! Be responsible with your information.
I am going to buy a Energizer charger that comes with 4 AA NiMH 1300mAh Rechargeable batteries, will this charger also be able to charge my other 4 NiMH AA batteries that are 2800mAh, 1300mAh to 2800mAh is a big increase.
You do see AA sized Lithium Ion batteries. Quite often actually. Ultimate Lithiums are my favorite and we've used them in the film industry for over 10 years now.
Seems like physics, specifically kinetic energy and maybe inertia, should allow for mechanical features in cars/vehicles specifically...possibly buildings if using gravity...to stoke the drawing of electrons, likely via magnets, possibly friction heat...to power multiple small electric motors, that can then fabricate piston engines, with air burst intake devices...However with chemical batteries it is surprising there isn't more anti corrosive additives possible...maybe even gmo'd bacteria to stop corrosion...Or a device that would use rf's or frequencies to stop corrosion...at least in cars or big machinery. Scientists know chromium is anti corrosive, so it's interesting two symbiotic bacteria cultures can't work in chemical batteries.
03:17.. so you're saying that the reason is simply that the primary cell has lower cost materials? That's far away from science.. chemical reactions don't think of the cost of the materials when it happens.. so let's not say that primary cells are not chargeable because it has lower cost materials like Zinc and Magnesium.
Electrons don't pass through the electrolyte, that would render the whole battery useless. Instead, they pass through the outer circuit, powering stuff.
0:45. why cathode called positive and anode negative. an anode is the electrode in a polarized electrical device through which current flows in from an outside circuit. Cathodes get their name from cations (positively charged ions) and anodes from anions (negatively charged ions).In a device that uses electricity, the cathode is the negatively charged electrode. Such devices include diodes, vacuum tubes, cathode ray tubes, oscilloscopes, electrolytic cells in hydrogen production and secondary battery cells in rechargeable batteries. However, in a device that produces power the cathode is the positive terminal, due to the flow of electrons being reversed. Such devices include galvanic cells and primary cell non-rechargeable batteries, as well as secondary battery cells (rechargeable) when the energy within the battery is being consumed.
NOT all batteries you see today are alkaline cells! We have alkalines, but of the ones I have to deal with are mostly NiMH, all AAA, AA or 9V. We have some things that use lithium button batteries and have just started to keep extras around. Our household has nothing that uses C or D cells. There are a lot of different battery chemistry today. Please don't say that the batteries you see a lot are all alkaline batteries!
I think you're wrong. Power flows from the negative to positive terminal. This means the anode is getting reduced and turns into its usually positive ions inside the electrolyte. The positive terminal is oxidized, this means dissolved ions well collect onto the cathode. The circuit is completed through the salt bridge where something like KNO3 well split into K+ and NO3-, and the NO3- well be attracted to the positive ions in the anode's electrolyte. And when you were talking about pH you recognize that a lower pH has more of concentration of H+ ? You're talking about OH- which has a high pH. Seriously Dnews, do any of you people even have science related degrees?
a simple curious question if you can kindly answer please. Given scenario: lets say I'm standing on the ground with a ball in my hand, when I throw the ball about 6 inches up in the air, the ball falls back into my hand due to gravity (and angle) now lets say I'm seated in a cart that is moving at the speed of 50 km per hour and I perform the same maneuver, by throwing the ball a few inches in the air (on a 90 degree angle) why doesn't the ball fall where it was first lifted, how does it travel 50 km in the air to fall back into my hand, should the ball not fall on the ground 50 km behind?
"When it comes to computers and other devices that use batteries" Nearly all phones/tablets/handhelds use ARM, and while I admit I am a bit of an outlier, my PC is AMD.
actually lithium ion cells can get as many as 3000 (and possibly beyond) cycles depending on what voltage you charge them to and the temperature you keep them at the reason your phone or laptop battery is practically useless after a few hundred cycles is because the OEM wants to kill it as fast as possible so you have to buy another one and therefore they can make more money out of you they do this in a many ways but here are the 4 most common ways they rip you off OVERCHARGING for devices that use a single 3.6/3.7V cell as the battery they deliberately program the charging circuit to charge it to the highest voltage they can get away with in order to rapidly degrade the battery (usually around 4.4V is the safe limit however some OEMs have been known to push the 5V mark) that is one of the reasons why a certain samdung phone got banned by the TSA because it catches fire randomly CELL DEBALANCING for devices that use multiple 3.6/3.7V cells in series (always used to ensure laptop battery death) they program the balancing circuit to stop balancing the cell voltages after a pre programmed number of cycles (usually 300-400) to give the illusion of a dead battery pack after about a year or two most OEMs also place the battery near the CPU or heat exchanger to speed this process along by overheating the battery the device will turn off when any one cell gets to around 3.2V and the battery stops charging when any one cell gets to 4.1V with laptops the issue arrises when one cell is fully charged at 4.1V while another cell is only at 3.6V for example then when you unplug the computer the battery will disconnect power when the low cell hits 3.2V that is why a major sign of a dead battery pack is the battery meter going from near 100% down to 5% in an instant or the computer just switches off (sometimes without shutting down first) then when you plug it back in the battery meter will often show a full or near full battery OVERHEATING THE BATTERY they may simply place the battery near the CPU or some other heat generating component in order to overheat the cells and degrade the batterys longevity sometimes to catastrophic effect (exploding dell laptops anyone?) UNDERSIZED BATTERY PACKS another thing that can rapidly degrade a batterys longevity is by overloading it Alienware is particularly fond of this method (they also use the cell debalancing and cell overheating methods) ever noticed that sexy new gaming laptop with 2 GTX1080s and a core i7 only has a 6 or (if you are extra lucky) 9 cell battery? its not just to give you less runtime so you use your OEM allocated cycles faster (though that was likely the original plan) when a battery is overloaded (delivering more current than it was designed to) the cells heat up internally and that causes the cells to very rapidly degrade (hence why cells used for vaping dont last very long before dying or catching fire if they are not specifically designed for vaping) my laptop which is an Alienware 14 2015 edition and it has a 6 cell battery gaming power draw from the wall socket while running crysis 3 at max settings is 120W minus about 20% for ineficiencies in the charger that leaves us with a load of 96W being drawn from the battery when unplugged (estimated since i cant measure the battery) the cells in the Alienwares battery pack are generic no name brand cells which in my tests cant handle more than around 2.5A of continuous load before they start to get hot (yes i canibalized a brand new Alienware battery pack to test this) 96W at 11.1V equals 8.64A which is higher than the 5A rating for 2 cells in parallel (the battery is in a 3S 2P configuration) Please note that Alienware is not the only shark in this pool Razer do it with their laptops MSI have started doing it with theirs ASUS have always done it with their ROG laptops Apple have always done it with their iPhones and their iWatch those are just a few OEMs that use undersized battery packs to force you to buy a new battery sooner than you should need to (dont you just love capitalistic corporate greed) as a consumer it pays to be in the know about how companies try to suck more money out of you than they deserve
omfg Chase, jump ship while you still can. I can't stand the level of advertising attached to "knowledge" here. Doesn't it feel dirty when those words come out of your mouth , an opinion paid for by Intel, with Emblem and all. Unsubscribed.
Pretty sure there are some Lithium ION batteries that come in the standard sizes. Also showing a BIOS battery for a lithium battery and high draw that's incorrect. The BIOS battery has perhaps a couple milliamps of draw, all this battery does is to keep the BIOS settings saved in a sort of RAM and keeps the system clock accurate. The reason I think these are lithium is either because that is the best way to get the needed 3V, or because they don't leak. These batteries can easily last like 8-15 years in a computer. Every computer has something like this laptops, desktops. Most use a CR2032 coin cell, some used odd custom ones or rechargeables, but that's uncommon. Phones, tablets I think use memory that don't need this, or maybe super capacitors, it's possible too that since these things are generally simpler there may just be something in the hardware firmware that acts like BIOS but is under many layers.
I normally love this pace for utubers but in the case of reviewing big concepts, NOT. I would: first state it for the layman in 2 sentences: this wont work due to X. Then, heres why and show charts slowing that part down a bit. Most people learn visually.
"Alkali battery acids have a high pH" ... No, acids have a low pH.... and the electrolytes in alkali batteries have a low concentration of hydrogen ions... not a high one.
That sponsor plug at the end was worthless lol, next time make it less obvious they that they gave you a script and act like you chose them to sponsor you; not the other way around. see anyone sponsored by audio books for examples. (vertasium, Smarter Every Day, ect.)
Aren't batteries extremely LOW on the PH scale? generally in the 0 - 1 range? Please help if I am incorrect, as I'm here to learn about this, but batteries produce a flourinating acid, right? How is this low in PH scale?
Current flows positive to negative, not viseversa... if you are talking about how the electrons move, its from negative to positive, but current is opposite of electron flow... cmon dNews basic phys 122
I recharged triple a batteries that were not rechargeable and it worked. I did it because they were the only triple a I had. So I kept doing that. I had a headset a pretty nice one actually and I was using the batteries in that and one day I put them back in and my headset made a high pitched noise with a weird sort of leaking crackly noise and I think I broke them... I checked the batteries and they leaked a white stuff. So yeah. You actually can charge them but try not to if you really don't have to. Let's say you going to the store in a couple days and you need some batteries sure charge them up but don't do it a bunch of times like I did.
Hi, im trying to teach year4 about electricity and im confusing myself. we looked at renewable and non renewable energy sources and how electricty is generated, however when we moved onto batteries and mains, they have allsorts of questions about how batteries generate electricty and why some can be charged. because these children are 8 years old i dont want to bog them down too much. is there a really simple way to explain this process
They do make Lithium Iron Phosphate batteries in AA size, I have some. The chemistry is safer than Lithium ion. However, the size means you can fry Electronics intended for 1.5v batteries if you aren't careful.
My phone dies at 85% I'm done and I'm not buying a new smartphone until they create one with a that doesn't completely break after a year and a half. I can't unplug my phone and use it for more than 10 minutes now. At least it lasts all day if I don't touch it.
Wait wait wait. Why isn't lithium practical in some applications? 3:38 ???? Here are the lithium AA batteries you say don't exist: search Amazon for lithium AA
Can you develop a food allergy by eating too much of that certain food? When I was a kid I love mushrooms, but developed an allergy to them. My mother always said it was because I ate too many.
while we wait for this battery , car manufacturers should build gasoline serial hybrid cars with a small turbine generator instead of a piston/cylinder engine for a lower cost higher mpg car, then when this battery get commercialized fit it in the car with the turbine generator range extender.
actually you can recharge primary batteries you just need a specialist charger (mines called a battery genie). its much slower and you only get a handful of charges but i can a sure you it works fine.
why hate batteries? the alternative is cords, those are annoying :D the only batteries I hate are those you can´t change, why have something like a headset which would only be part wireless. there is a reason you buy them wireless in the first place
just finished reading some of the other comments and I feel people need to be slightly more tactful when putting forth their feelings about sponsors. it is possible to not like how something is done and still maintain a modicum of respect for the person doing the video.
I was not expecting the in-video advertisement. That's kind of rare and dirty. I just wanted to learn about batteries, not be advertised at :/ Disgusting sellout.
I am doing engineering still I dont no how an a.c works I know that its work on cycle half +ve and half-ve but how does the polarity changes and still we get max power than same d.c sorce
Wait you have to throw batteries away in a special place... my life is a lie... A good question to answer on dnews is... Why can't you throw away batteries in the trash can?
I would join forces with Darth Vader suck all the energy from the sun with our death star and rule the world. Intel is going to get my first batch of death ray energy!
I wonder if he felt dirty inside after that shameful piece of sucking up to the advertisers. He is probably still in the shower now trying to get clean again.
Your wrongThe anions dont suck the electrons from the anode. The anode is the one that sucks the electrons from it. And then the cations suck the electrons from the cathode
so batteries have intel inside ... and thats why ... aha and cuz water haz electrolytes its good for our plants now all makes sense to me i like money txs dnews
why cant the charger force the electrons to stream backwards into the primary cells? I mean what is it that makes the chemical reactions not reverse efficiently
