Killer Amps
I want to pull ten amps out of a little 35 ah battery for one hour and then fully recharge. Will this heavy draw destroy the battery? I know it is a small battery.

at this battery size I ahve to ask if it's a AGM or liquid. (LIquid would be like a garden tractor battery or motor cycle, though if I had a cycle that is one place I'd use AGM)
I woudl say try it. draw your 10 amps for an hour (10 amp horus) let it sit for like 20 mintues and measure voltage.. If it's too low add more battery
if it's still at say 70% recharge
NOTE: for batteries other than DEEP CYCLE 70% is too low. DEEP CYCLE (Golf car mostly) can go to 50%, but Starting batteries and MARINE/Deep cycle should never drop below 75-85% depending on the battery so you are likely doing damage .
You can also google the Effect (purket? Someone mentioned it above) and find some calculators that may help you find your discharge level.
actually a trojan GC will give hundreds of cycles discharged to 25% SOC (75%DOD) spec's say it, and my experience confirms it. 10years life on a set with well over 100 discharges to near 25% SOC. I suspect most other decent GC will do similar.
