Quote from iplay1515:
I purchased the battery for $20.00 in Lake City, CO from a camper who was rebuilding his solar system. He switched to a gel battery system.
These CAT batteries seem to last quite a long time if a charger is used that can remove the sulfation from the plates and they are rejuvenated two or three times a year.
Be sure to use the proper size wire and either a fuse or circuit breaker between the auxiliary battery and the internal UPS battery.
The only reason I keep my internal battery in place is so I will have a system that functions when I'm doing maintenance on the CAT battery. I just turn the circuit breaker off and connect the charger to the CAT battery. The internal charger in the UPS keeps a float charge on both batteries.
If the power is restored via battery or generator, is it likely that trading is still disrupted as verizon fios is down for the same reason the brought down the electricity?
