If you have a battery pack that is no longer working correctly, then you might want to know how to identify and fix a broken battery pack. Lithium-ion batteries are used all over the world every day to power all of our gadgets and gizmos. Whether it's your smartphone, your laptop, or in some cases, your vehicle, lithium-ion batteries are at the heart of it all. Lithium-ion batteries are great and all, but they aren't perfect. Just like any other battery technology, lithium-ion battery cells eventually break down and begin to no longer function at their specified ratings.
That’s exactly what I was thinking. I worked on electronics 25+ years in the military, so I know a thing or two. Those two terminals that the battery uses to make contact with both the charger and tool are no different than the contacts within the battery. So doing this pulse exercise on those exterior contacts will
This will cause the cell voltage to drop and cause heat to build up within the cell. It also means that your battery will die on its own, even with no load connected to it. So if you see dented cells in a bad battery, it's kind of a good thing. It means that that’s more than likely the only problem and the rest of the cells are good. Don’t just go on looks, though. You should always use a multimeter to check the voltage of any questionable cells.

You have to pull it apart. you need to pulse it at a point before the circuit board. the charger clips are after. I just did 3 batteries each for about 1 minute they all revived. I did see a version where someone drilled thru the case at a point where the contacts are rather than dissemble. but I think that would expose the system to moisture.
So if one goes bad, it's more than likely going to negatively impact the surrounding cells. If left unchecked, a bad lithium-ion battery can overheat and go into thermal runaway, which is never a good thing.
Another aspect to consider is that given Apple reduced its price for iPhone battery replacements so recently, an influx of customers are rushing to take advantage of the deal, which can result in hours-long waits at some stores. Keep in mind that the discount is being offered for an entire year.
You do not need to pay anything until your iPhone is repaired and back in your hands. Once you get it back, you can pay either by cash, card, UPI, Wallet, Online or Bank Transfer, whatever is comfortable and convenient to you.

Well, I will still ask, Maybe someone out there can help. Have a HP DV7 Notebook with a 9C battery. 3 cells died over night. from running normily to zero. Disassembled battery to find 3 cells died. zero Volts. Replace the 3. Now have ~12.6V. Will not charge in windows, Shows 80%. ran Bios battery test. Battery status : Replace (42). was wondering if anyone out there has a way to reload the firmware in the battery charging pcb or edit that data? Many thanks David A.
