Hi all, i have a 120 Amp Hour/850MCA deep cycle marine battery lying around, and i was thinking to myself "isn't there a way to hook this thing up to my APC for some insane uptime in a power outtage?" My question is, can i do this? The battery is brand new, but i don't know if it is going to overload my apc or if there are any other problems with doing this? Thanks in advance!
