Thank you Skipbee. I am considering AGM's for my next bank of batteries and have one of the best chargers that will babysit them properly.
My only concern is the lower AH rating that AGM's seem to carry when comparing.
I do want faster charging and longer lasting capacity when batteries are sitting idle.
Can a couple DEKA's in parallel handle running the furnace all night?
I assume you mean a propane furnace with a 12V fan? The fan would draw less than 4 or 5 amps, which would be 40 or 50 amp-hours over a 10 hour night. Almost any battery could handle that.
