Makes me feel better now) Stupid question dept: Are we SURE they are 12v ?? I didn't verify them - I went off the experience of the Batteries Plus tech. I did have a set of batteries on my old UPS that were the same physical size BUT they were 6 Volts! Use the assumption rule - Just double check that the batteries are in fact 12v before you charge a 6v battery on 12v charger. Messy things can happen otherwise. If they are in fact 12v, they could work up to 650va UPS's). *** On Another Subject *** I will not be there next week <frown> I have my a daughter both nights.
