And that was with manufacturers not doing anything very stupid, Th but something just a little bit wrong. Thanks for the warning. I've never had any success reviving dead Li batteries so the advice to be very careful is gladly accepted. hi, Do you know, what is the relation between charging time, voltage , capacity, charging current in lithium ion rechargeable battery. suppose how much time it will take 6000mah battery charging with 100mA with 4.2 volts. |
