Our take on the Duracell Ultra BCI Group 27M 12V 100AH 620CCA AGM Deep Cycle Marine RV Battery

The Duracell Ultra Group 27M is a sealed AGM dual-purpose battery for boats and RVs. It is rated 100Ah and 620 cold cranking amps, so it can run a trolling motor or accessories and still start an engine. AGM construction is spill-resistant and needs no water checks, which suits owners who want low maintenance. Against flooded Group 27 batteries it costs more but handles deeper discharges and vibration better; dedicated deep-cycle AGMs trade cranking power for longer cycle life.

Questions and answers

Is this a starting battery or a deep-cycle battery?
Both. Duracell rates it as a dual-purpose AGM: 620 CCA for starting and 100Ah for running accessories. It is not a pure deep-cycle battery, so expect fewer deep cycles than a dedicated one.
Does it fit a standard Group 27 tray?
Yes. It uses the BCI Group 27 case size, so it drops into most Group 27 trays and boxes. Check your holder's height clearance, since AGM cases can be taller than some flooded batteries.
Can I charge it with my regular battery charger?
Only if the charger has an AGM setting. AGM batteries want a slightly lower absorption voltage than flooded ones. A standard flooded-only charger can shorten its life.
Does it need maintenance?
No watering. It is sealed and maintenance-free. Keep the terminals clean and tighten the connections, and recharge it after each trip rather than letting it sit discharged.
Can it be mounted on its side?
AGM batteries are spill-resistant and can be mounted in more positions than flooded batteries, but check Duracell's mounting instructions. Avoid upside-down installation and secure it against vibration.
How does it compare with a flooded Group 27?
It costs more but is sealed, vibration-resistant and needs no water checks. A flooded battery is cheaper and can be equalized, but it vents gas and needs regular topping up.
Where is the Duracell Ultra BCI Group 27M 12V 100AH 620CCA AGM Deep Cycle Marine RV Battery cheapest?
At Batteries Plus, for $299.99, as of our latest check.
