If you buy a farm rated battery and you treat it well, it should last for at least 8 years. Treating it properly: 1. keep it charged while sitting. This may be accomplished with a battery maintainer or by periodic toppoff with a 2A trickle charger. 2. Make sure you are not overcharging with the generator. I use a voltage regulator on my generator, works perfect. 3. Make sure you have clean electrical connections and heavy enough cables, Also a good idea to run a ground strap from ground on battery to the engine block. If you have to replace your battery more often, you've got a problem somewhere in those three things. Yes, you may have gotten a bad battery, but not likely more than one.
