Re: APC Batteries.

<idiot alert!>
I modded a 700 to use 2x 12v car batteries, in series, and got great
run time (over 2 hours, on my rack), but the first really deep cycle
killed both the batts.

The APC 700s are pretty smart, and learn the charging profile of the
batts, but it'll still let them discharge fully - which in my case was
too much.

Gel cells don't mind deep-cycle, so this should work perfectly.  and
you don't need any baking powder :-) [don't ask!]
