24DC vs 27DC Marine Battery – What’s the Difference?

24DC batteries are a smaller size, lighter weight and slightly lower capacity.  27DC batteries are a larger size, have higher amp hour capacity and a longer runtime. If space is limited in your battery compartment, Group 24 is often the preferred choice.

Can I use a 24DC battery for a trolling motor?

A 12V trolling motor system can use a Group 24 deep cycle battery however, we usually recommend a battery with higher Ah such as our 31DC. Verify your motor’s amp draw and runtime requirements before purchase.  See our Trolling Motor Battery Guide for more details.
