Any lead acid battery lasts longer (lifespan) if you don't discharge it down to a small percentage of its capacity. Many recommend a limit of 50%. If you usually draw off only 10-20% of capacity and keep it on a quality charger the rest of the time it will usually last for many years.

My point here: Buy as much capacity as you can afford and fit, to avoid draining it down far.

Ask California98Civic. His small (16AH?) single, high quality AGM failed after maybe six months of regular deep draining.
