RE: Viper 500 info
Druce,
Ditto........
I use 6 v 700 milliampe AAA Nimah also. Works great. The Fuel tank compartment is tight but it will fit. Some guys will use the round bladder type fuel tank which can be set further back in the fuse which give you more room for the battery. Depends on your fuel set-up, either way this size battery is good.
Good Luck
