Well, at a 1 amp draw, the amp hour rating will be higher of course. Kinda
like specifying 40 mpg on a car with an asterisk (*@25 mph).
For backup where the commercial power is pretty good, and if you can put them
in an environmentally controlled place, they should do OK. I am building a
cheap and dirty backup for the office. Cheap 2500 (5000 peak) watt chinese sine
wave inverter. Valere/Eltek used rack mount rectifier off of Ebay.
Gonna try to run it 100% on inverter with an inverter powered relay that will
allow it to fail over to commercial power.

The weight is consistent with 100ah batteries I've bought in the past. That
would put it closer to 7.2 cents per watt/hr....still decent.

Anything that has a label on it with cranking amps is not designed to be used
in cyclic applications... Very different internal plate design versus an
Outback 106RE or similar.
Lead acid batteries designed for cyclic use (PV/wind) or telecom/float use
will have a datasheet with 1 hour and 20 Hour discharge rates. Nowhere on the
datasheet will you see "cranking amps" or CCA.

Doesn't come much cheaper than that.
