I like electronics but I basically don't know anything about it (electricity is too complex), the thing is that I've opened a battery from an old laptop that reads "10.8 V 4300 mAh Li-ion"
The battery-pack contains other 6 batteries and a circuit inside, I suppose that the circuit is just for showing battery info in the computer, charge indicator and for preventing 'overcharge'. Batteries shows 2x 0.0 V, 2x 3.11 V and 2x 3.17 V (with a tester), but that's just their current charge, there's no info on them more than a serial number so...
There's a way to SAFELY recharge them? I'm not in a hurry so time is not a problem.
I thought about put them 0.5 V higher than they currently have over and over until they don't get any higher voltage, but I'm not sure if that will work nor if that will even recharge them.
PS: I thought that Li-Ion batteries didn't contain a pack of standard batteries inside...
