Hi
I am ripping my first batch of laptop batteries and have come across a few anomalies.
A fully working laptop battery Dell FV993 11.1V 97WH with 9x 18650 model Samsung ICR18650-30B and all cells are testing at 6.04-6.45V each.
I thought that my Voltmeter may be faulty so I tested a rechargeable 1.5V AAA battery and that returned 1.7V. Also opened another laptop battery and tested the cells - all around 3.4V
The third battery pack with 3 cells Samsung ICR18650-30B also 1st cell 1.82V and the remaining two 5.46V and 5.48V
Is Voltage above 4.2 possible for 18650 and what should I do about the 5V+ ones?
Thanks
