Wes says he has his batteries on a lower float voltage. The extra amount of 
charge you get per 0.1V is small once you're above 12.6V for the battery. Sure 
if you're counting on getting the last minute of power out of your UPS, then 
maybe. But if you're only handing power bumps lasting seconds, like I'm doing*, 
then I'd rather have 10 years on a battery, than 2 year. In that case the float 
voltage shouldn't be much above 13.2V/battery.

you there.
