I just was given two 36 volt Dewalt drill batteries that would not
take a charge. I opened them up and found what looks like the charger
unit built right into the battery pack. These batteries are about the
size of C batteries but a little bigger. They measure about 3.2 volts
apiece. I know that these are li-on cells because there are 8 monitor
wires going into the charger unit. One pack has one bad battery and
the other has several bad ones. I also have a set of these type of
batteries that came out of a laptop. The shame of it is I really can't
do anything with any of these good cells because I have no way to
recharge any of these. Does anyone know of a generic charger for li-on
cells or some way that I can recharge these? Thanks, Lenny
