Cheers, Jon,
Just what I was looking for. Most of the links here sell batteries, but no mention of chargers. I'll phone 'em tomorrow morning.
My battery might be charging okay with my US E-Bay charger, but since there's no LED light on it; I'm not sure if it is or not.
I'll go to work with it, and if it conks out, I'll get my trusty ladders out and try not to fall off 'em.
