    UPS batteries in series or parallel? ME-1000-BK Mecer 1000VA OFF-LINE UPS

    Hi My old Mecer ME-1000-BK offline UPS takes 2 small 12V (7Ah) batteries. I'm not sure whether the UPS runs off 24V or 12V when on battery power, and hence whether to wire up the 2 12V batteries in series (24V) or parallel (12V)? Can't find any docs online... Does anyone know please...
