I would like to take this topic one step further. now that we know
what to do and use for battery backup ... what are the
recommendations for a solar setup? Where you use the batteries as
your power source. Deepcycle batteries? UPS batteries?

You will only have the opportunity to deep discharge them maybe 4 to 5
times. Wet electroyte
deep cycle batteries are an option at a reasonable price as long as you
don't mind the acid.

The sealed lead acid cells have a much better deep cycle capacity. Just
don't overcharge them.

Do a Google search and you will find an education in backup
battery scienceI found the GE supply wont properly charge my
sealed lead/acids,so I use an additional float charger with an
equalization switch and equalize them monthly.Makes a HUGE
difference in capacity and battery life.Car

Given that batteries used in backup service rarely get cycled at all,
wouldn't car batteries be a more cost-effective choice? (assuming the gel

This battery has worked beautifully in my situation.
YMMV.

Got a small question, I have recently been given a pair of 12 v BAT_0103
batteries. These are sealed lead acid cell (UPS) and are 75 amp hr. I am
currently using a pair of car batteries as battery back-up. Are the sealed
ones better to use or does it make no difference. The GE power supply will
