Hi.
I got a 9.6V battery-pack from a cordless Bosch that's in a "funny state". It doesn't seem to be very old but it wont charge to more than 4.7V. It can deliver some 2A at ~4V for 10-15 minutes and it can be used to drill small holes.
This leads me to thinking that only half the cells are good and that the rest are somehow shorted?
I've read about people "flashing" battery packs with a big cap charged to 50-100V? Any hints on this?
Do i perform the "defibrillation" once ore what?
What's "a big cap"? (10mF, 100mF, 1F?)
Thanks in advance.
Regards TroelsM
