    Batteries

    What's the difference between a series 31 AGM and series 34 AGM? Is it just the physical size of the battery? TIA

    No. The 34 has lesser specs, in particular, the Reserve Capacity.

    A 34 is just a little bigger than a lawn mower battery. It’s the smallest marine battery made. 31 is the biggest commonly sold to consumers. Capacity is directly related to physical size.
