It seems that because the AGM batteries can cycle 1000 times versus the 300 times (at 50% dod) for flood cells the AGM are 1/2 the lifetime cost of the Trojans even though they cost twice as much.Īlso, I ran the numbers for an Exide Nautilus gold and came up with a Cost / 10000 ah of $79.42. In looking at all my options I ended up back at the batteries. I started looking into solar to 1) extend past 4 days and 2) use more power. My wife likes the stove fan on when she's boiling water. BUT it's getting colder and we'll want to run the furnace. If I assume a 50% dod over 4 days that means I consume 13.6 ah / day. As a rough estimate the current batteries have about 108 ah - TOTAL. ![]() ![]() Right now I have 2 interstate batteries - one came with the trailer the other I picked up from WalMart. ![]() Hi All - I've been reading for a while and gleaned some great knowledge here.
