joeargy: I luckily stumbled into dis thread, are u sure an apc 650 ups can charge a 100ah battery? If it will, how many hours wil it take to fully charge?
I asked a battery charger and he said its imposible, i know u are more educated than he is but what of experience? Can u pls explain. Wont it over heat the apc 650va ups and set my face2face room on fire while i'm not at home? Pls reply
Thanks

Hello, it won't overheat the inverter but it will take a very long period of time to charge the battery to its full capacity.
on the issue of how long it will take, that depends on the charging current of the UPS, which is relatively low.
It may take a typical650va UPS more than 4 days to charge up a 100ah battery back to it's full capacity and the ugly part of it is that it will might take just 4 hours to discharge the same battery capacity.
