I understand that BW, but does it recharge batteries or is it a power
supply for a spark generator. I would think the latter rather than the

is not good for the battery.

I've not known any that use a rechargeable battery. After all, in the
event of a mains failure you could use a match...

Might have a back up battery if there's a clock/timer, though, but then
again I doubt it.
