So when it comes time to replace your batteries, what are most of you buying?

In my situation, our a Formula 270 BR lives in a valet marina and the batteries go inconsistent periods of time without a charge and its undercover so a solar charger will not work.

Worse yet, it is stored all winter with no charger,,,

Clearly this is the worst situation you can subject a battery to, so whatever I choose needs to be super resilient.

Thanks!
