What vehicles use a Group 31 battery?

Group 31 batteries are common in heavy-duty trucks, commercial vehicles, RVs, marine vessels, and equipment with high electrical demands. Check your vehicle's owner manual or existing battery group size to confirm compatibility.

Does the AGM design make a difference over a standard flooded battery?

AGM batteries seal the electrolyte in fiberglass mats, so there is no free liquid to spill. This makes them more resistant to vibration, faster to recharge, and better suited for deep-cycle applications. DEKA rates this battery at twice the cycle life of a conventional flooded battery.

What type of terminal posts does this battery have?

The 9A31 uses 3/8-inch by 16 stainless steel stud posts. Make sure your cable ends match this stud configuration, or use appropriate adapters if your cables have top-post clamps.

Product Details

Inside the box you get a Group 31 AGM battery from DEKA's Intimidator line, rated at 925 cold cranking amps and 1,060 cranking amps. The 190-minute reserve capacity at 25 amps means there is substantial backup power if the alternator drops out, and the 100 amp-hour rating at a 20-hour discharge rate suits vehicles with heavy accessory loads.

Absorbed Glass Mat construction makes this a sealed, maintenance-free battery. There is no water to check and no acid to spill, which matters in commercial trucks, RVs, and marine applications where the battery gets bounced around. DEKA rates the Intimidator for 20 times more vibration resistance than conventional flooded batteries, along with faster recharging and twice the cycle life. The gold cover and gray case house 3/8-inch by 16 stainless steel stud posts, and a carry handle makes positioning the 67-pound battery in tight battery trays easier.

Dimensions come in at 12.99 inches long, 6.73 inches wide, and 9.49 inches tall. Verify your battery tray measurements and terminal configuration before ordering, especially on commercial or marine applications where Group 31 trays can vary slightly.
