I zapped my Bosch drill battery without removing the casing and successfully revived it. You do NOT have to buy a new $50 battery.

For a 12 V battery pack, which has 3 cells, the voltages will be more like: Micah, I agree that directly applying an uncontrolled charge voltage to a Li-ion cell can be disastrous, and that charging above 4.2 V per cell is definitely bad, probably dangerous, BUT, the whole idea, as shown here, does not involve continuous application of the charge, it does not bypass the thermal protection, it does not connect directly to the cells, and the wires are definitely not “designed” to connect continuously to the contacts…moreover, Karen specifically suggested short pulses, and continuous monitoring of the pack voltage, and only providing enough voltage level to “turn off” the UVLO circuitry…if one ignores every part of this process, and connects directly to the points shown, this is still at a point where the primary safety mechanisms of the pack are functional. – In this case, any AC adapter with a rated voltage about 6 VDC should provide about 8 V with no load, which should be “good to go” to re-energize a 12 V battery pack. Another of your brilliant ‘stuff’ I can steal. If the charger that’s designed for the pack isn’t working, there’s probably a reason for it. Thank you :).

A 18 v battery poses almost no danger at all. ;) ~ karen! I really don’t know how much experience you have at this technology, but this level of rhetoric is well beyond what is appropriate… maybe, something like:”not following the recommended procedure, or connecting voltages to points other than suggested, can result in damage to the battery pack, and danger of the battery pack catching fire”, Hi Karen – you’re fantastic – I read almost every one of your posts, and the great comments as well.

I was stationed in Newfoundland with the United States Navy back in the late 60s…and I did find the locals ‘industrious’ as you state. Normally, the battery pack protection circuits will shut off the battery at about 2.7 V to 3 V per cell (13.5 – 15 V for your 18/20 V pack of 5 cells), and allow charging, BUT, when the cells discharge to about 2.3 V each, the battery control system will shut them off, internally, to avoid further discharge from totally “killing” the cells; at that point, the tiny voltage that you see on your multimeter is from the tiny amount of “leakage current” getting through the “kill switch” circuit. If you have any issues locating items, please contact us at 1-888-909-6757.
