Re: APC Smart-UPS float voltage experiment

I've got 2 SU1400 backups and I've converted one to run on 2 Deep Cycle batteries. Having been new to this I didn't check the electrolyte levels on the batteries and they boiled dry!

The UPS reports 27.6v battery level but according to my meter it's 28.2v So I'm guessing that's why it boiled both batteries dry in 8 months. And explains why it would go through APC batteries in about 18 months. I tried the software settings to change the voltage [URL="http://www.jjoseph.org/notes/apc_smartups_battery_float_voltage"]http://www.jjoseph.org/notes/apc_smartups_battery_float_voltage[/URL]...
