I have some old batteries from a notebook computer. some are flat type, and some are round.
The flat one are at 3.73 volts, and the long round ones are 4.15 volts.
Are they both Li-ion batteries ? thats what it said on the battery cover.
However, I don't understand why are they in different voltage ! Is it normal to have 4.15 volts Li-ion batteries ?
Any idea ?
