I'd try Googling the battery model number and see if anyone is selling
them on Amazon or eBay.
So far as I know, the only rechargeable battery packs that can't be
rebuilt with new cells are Li-Ion battery packs. Apparantly, each
Li-Ion battery pack has it's own circuit board inside it that monitors
the voltage of the pack and will shut it down before the voltage gets so
low that the circuit board forgets it's own programming. You can't
rebuild these battery packs without removing the power to the circuit
board, and thereby causing it to lose it's programming so that even with
new cells, the rebuilt battery pack is useless.
An alternative might be to just buy yourself a corded trimmer and chalk
this one up to experience.
