Marine Batteries

Tucker,

For those of us who do trailer our boats you make some excellent points with regards to readily potential availability of replacement. Few, if any of us use significant current between engine operations so the deep cycle and AGM advantages are not generally fully utilized. Further, generally speaking, the lead/acid type battery delivers higher usable amperage for cranking engines than the other designs. The also recover faster and are replenished more quickly than their other design counterparts.

On larger boats with more electrical demands when at rest (refrigerators, TV's, A/C, etc.) deep-cycle and AGM designs become more practical design for those applications. Further, most of our boats depend on our propulsion engine for our electricity generation and it is not ideal to mix battery types for simultaneous unregulated charging purposes. Mixed battery type configurations are optimal when a charging regulator is appropriately sized and installed in these situations.
