This Victron Energy AGM deep cycle battery is a 6V, 240 Ah sealed unit from the Super Cycle range. The chemistry is aimed at repeated deep discharge, and it is stated to handle at least three hundred full-depth cycles in the maker's test. It is a sealed, valve regulated lead acid design, and self-discharge is under 2% per month at 20°C, doubling with every 10°C rise. The maker points to occasional full discharge or frequent 60-80% discharge as its intended duty.
Our take
A rating of at least three hundred 100% DoD cycles means this 6V Super Cycle battery tolerates being run flat now and then, and under 2% monthly self-discharge means it holds charge while a boat sits. Warm storage speeds that loss, since it doubles per 10°C.
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.
