How do NiCad and NiMh chargers detect -deltaV to stop charging? (SOLVED)

AJB2K3:
Something that may be of interest (very loosely) is that I was able to revive some Li-on cells that had dropped down to 0.2 volts and wouldn't charge.
PSP 110 Battery Revive. | Ajb2k3's Weblog Not very informative but it did work.

I think Boeing tried that already :wink:

LOL But I don't think Boeing is laughing at the moment, it's costing them a fortune in downtime and whatever rework falls out is bound to be pretty costly as well. Li-po cells are great from a energy density and current capacity point of view, but they do bring along a lot of care and feeding rules to be as safe as past battery types.
