Quote from Catoosa:
I have bought 6 APC units over the years. Four are still in service and 2 have failed. The two that have failed were the smart units. Of the 4 that are still working, 2 are smart 700 units. As for replacement batteries, I have found the cheap replacements from eBay last me as long as the high dollar replacements I bought a few years back. I generally get between 2 and 3 years out of batteries. The last 3 units I bought were used from eBay without batteries and those units have worked as well as new units at a fraction of the cost of new units.
