You need special 12V batteries with liquid gel electrolite
like the ones used on sailboats and marine industry
rather than standard liquid acid car batteries. The gel
ones are more expensive but they can be totally drained
and recharged, they are more durable that car batteries,
they do not leak fumes, do not require refills, work in any
position and can tolerate much more abuse. When I lived on
a sailboat, I used a 12 v --> 110/220 v marine inverter and one
12 v battery was enough for 3 hours of computing or 2 hours
of watching tv until the battery was drained below acceptable
level.
