My Belkin 400 watt UPS has dead batteries. It turns out they are 2 small12 v batteries in series. I took two motorcycle batteries, wired them in series and connected them to the old battery outputs (disconnecting the old batteries). Seems to work great. There is still a trickle charge going into the motorcycle batteries. They maintain the output nicely when I unplug the UPS. I just now have more objects on the floor than before. I wire tied the two batteries together, drilled a hole in the UPS and have a wire pair going from the batteries to the UPS. Any known issues in doing this?
