I have a customer who wants to buy twelve 12.0 volt 8.0 AH gel cells from
me. He uses these in his fire alarm panels and wants to keep a quantity in
stock for when one of these panels goes down for battery failure. I've
explained to him about the need for trickle charging these while they're
sitting on the shelf, and rather than sell him 12 individual trickle
chargers I was wondering if anyone knows of a cost effective series charger
whereby I could put perhaps 6 in series and charge them all at the same
time. I would probably not want to go above 6 and I would not do this with
anything other than new batteries all of the same type and rating. Thanks,
Lenny

Gel cells should all be charged in parallel from a constant voltage source.
Usually about 13.8 to 14,0 volts. You might install a fuse in each leg of
the summing point just to be safe.
