The Odyssey ODP-AGM34M is a 12 volt AGM battery from the Performance Marine Series, rated at 810 CCA and fitted with SAE/marine terminals. The maker lists it as lead acid with AGM-TPPL technology. The case measures 10.9 x 6.8 x 7.2 inches (275 x 172 x 187 mm) and the battery weighs 47 lb (21.5 kg).
Our take
The ODP-AGM34M is rated at 810 CCA and weighs 47 lb in a case 10.9 inches long, so measure your tray and hold-down against that footprint and plan how you will lift it into place.
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.
