[Glowing Bits!]

I've heard of the Ross brand but never came across any of their batteries, it's a bit before my time, the perspex lid was primarily for Ni-Cd batteries incase they exploded during charging, it's not needed for other types.
Years ago, I bought a Uniross charger with auto shut-off primarily to charge D cells for an airbed inflator, the said airbed did have a few uses at rock gigs.
The pic below is of said charger, it now only sees occasional use when charging solar garden light batteries.
