The Interstate 34M-AGM is a Group 34M dual purpose AGM battery for marine and RV use. It is meant to do two jobs, cranking the engine and powering a trolling motor. It is rated at 800 cold cranking amps with 62 Ah and a reserve capacity figure of 125. Interstate says its service life should run twice that of a conventional alloy AGM battery, and that it recharges faster.
Our take
Rated at 800 CCA and 62 Ah, this battery is built to both crank the engine and run a trolling motor, so one unit covers both jobs. The maker also expects its service life to run twice that of a conventional alloy AGM.
From our buying guide
A starting battery delivers a short burst of strong power, a deep-cycle battery a low, steady level for longer, and a dual-purpose battery a balance of the two. Buy for the job it will do.
Check before you buy:
- You've measured the tray against the maker's real dimensions, since a BCI group gives maximum sizes and some batteries sold as a drop-in run longer.
- You're comparing the same rating. Cold cranking amps are tested at 0°F and cranking amps at 32°F, so the second number is higher.
- If it's lithium, the maker says whether it may start an engine, and NMMA advises contacting your boat's manufacturer or a certified technician before replacing lead-acid.
