Here we are, I got the big 400 amp hour Surrette battery's out of storage and after almost 5 months of non use, they are exactly at 80% full. You just gotta love a great battery like that. Your not gonna do that with your T105 golf cart battery's - they are gonna be toast. Just to be extra careful while running the test I also hooked in a 10 amp fuse and a Anderson connector as I will be gone for a few hours when it's hot - but will still check in with my security system. I'm hoping for a 20 deg temp drop & Bruce is hoping for 25 deg - I hope he wins.
