Darn, the van needs a new battery.

This vehicle tends to see long periods (months) of not being used. I don't always remember to plug in a maintainer. So I replace a comprehensively dead battery every 2-3 years. Irritating.

I'm thinking of getting a deep cycle battery (RV/Marine) this time. Idea being it will survive being left to discharge for six months.

Good/bad idea?

Vanagon. Group 41 battery. Mild climate, always starts instantly.
