AGM battery is the least I will buy for anything, I even have AGM batteries in my car, truck, tractor, jeep, wife's car, lawn mower, garden tractor.
If anything, don't have to deal with the corosion on the terminals that you will have to deal with on a normal battery.

I have a good battery supply store close by, that is all the sell batteries and chargers, and repair chargers and batteries.
Prices are always alot better there for the same product than chain stores.
