The laptop cells are 3.7v. I decided to charge the two cells that were only 2v at 50 ma rate. Well they are up to 3.65v and holding. I'm slowly charging the other pairs of cells at a slow rate too. Voltage is increasing too.
I don't fully understand the electronic chargers inside battery, but I'm guessing my cells are good, just a screw up with the electronic charging system. If I had another laptop battery, I would be tempted to make an 18v battery for my dewalt tools and make a charger to slow charge them, say 100 ma.
BYW, my cells show no signs of getting warm. Been charging for a few days, no fires.
From what I've read, Li batteries catch fire when discharging, thermal runaway.
What do you think?
