phew, 120 lbs. how much?

i note right under the 153-5710 PHO is a similar sized VRLA (SLA), this
would be a better choice albeit probably significantly more expensive.
Since its NOT a vrla, it has vents even if there are no removable vent
caps, so this battery MUST be mounted in a ventilated battery box and
not used or charged in a confined space like a car trunk.

I was about to ask what the AH rating is, but I found the PDF with the
full specs http://www.cat.com/cda/files/192183/7/PEHJ0073.pdf

200AH at a 20 hour discharge rate (which would be 10 amps)... While
this doesn't scale linearly for lower discharge rates, its close
enough. thats a lotta pookah ! Something like 2400 watt hours... so
it would run a 100 watts of stuff for 24 hours straight (in theory... of
course in reality, there are various losses).
