Anything less and one cell may have failed, so the charger will simply refuse to charge it because it is ‘probably’ damaged or faulty. So get ready to act accordingly. Second… Maybe it’s time so switch to DeWalt. So after the pulse fix. Its risky to solder wires to any battery, let alone rechargeable ones. I haven’t had an issue with mine since fixing them so I haven’t been able to test it out. Der, you should propose to Karen, cause you could be an exlosive pack of energy together (poor pun intended).

And of course never short or touch plus minus of 2 cells together ever or short them. We are assuming we DON’T have a bad cell, and we are trying to bring up the charge ‘safely’ little by little. Once they heat up, they can melt or deform the insulating layers inside the battery cell causing an internal short, then the battery will ‘run-away’ and completely discharge in seconds generating a huge amount of heat, often it is enough heat to ignite the lithium or the other materials the cells are made of.

The only I saw you didn’t put in was almost electrical devices the listing is rated always by labs and engineers at Max rms is 80% if it’s true 100% to allow the circuits to work. Lithium based batteries, even when almost flat, store a huge amount of energy, not electrical energy, but chemical potential energy. Step 11. So, if the lithium-ion battery in your smartphone has seen better days, there are a few things you can try to bring it back to life before spending the cash to replace it.

But, did you say something about changing the battery of your iPad? If the charger that’s designed for the pack isn’t working, there’s probably a reason for it. Once added up the cost of the replacement cells isn't far off from just buying a new battery, and saves you much frustration and having to try to glue the pack back together not to mention risk of it shorting out while re-assembling.

I realized it was only a 5V charger when it charged the batteries to 5V at the charging leads (which barely registered at 0.2V through the battery circuitry at the normal connections). I have it on good authority that Ryobi doesn’t think so. Just keep repeating the “pulse” boosting and testing the battery until it will finally be recognized by the charger and you get the green light. Correct, but voltage allows current to flow for a given resistance. ~ karen! Thanks for the post, btw. Even if you leave the battery, the charge wonât deteriorate at all. I can only imagine the joy of living with a wife who knows this stuff……. Ha! I’ve stuck with you because you’re helpful and cheer me up. Extreme cold is usually not good for a Bat., but in the case of non-charge holding or a dead cell bat., The cold shrinks all the molecules that make up the battery, including the terminals, squeezes whatever is left out of it....THEN try the USB trick...has worked foe me in the past , especially LAPTOP BATTS....I know it sounds a lil' nutz, but it works.... Like Jan Zelman said, it's not going to work, Li-ion batteries are extremely sensitive to discharges and doing a full discharge will only damage the battery further.
