Re: Stow away 105 amp hour battery...how long will it last?
From my understanding about batteries, you may get 500-700 cycles, depending on temp, discharge/charging profiles. More if you equalize the cells appropriately. Also, you should be planning on a budget of about 50-55 actual A/hrs from the battery. Also, you may have better performance/longevity from a true deep-cycle battery as opposed to a duel-purpose battery that can double as a starting battery.
