The Duracell Ultra Group 31M 12V 110Ah AGM battery is a sealed lead-acid deep-cycle battery designed for high-demand applications like marine, RV, and solar systems. Its absorbent glass mat (AGM) technology ensures spill-proof operation, vibration resistance, and maintenance-free performance. With 110Ah capacity, it supports sustained power delivery and deep discharges while maintaining longevity—ideal for trolling motors, off-grid energy storage, or backup power systems.

What applications suit the Group 31M 12V 110Ah AGM?
This battery excels in deep-cycle scenarios requiring stable 12V power. From marine trolling motors to RV house banks, its 110Ah capacity sustains multiday use. Pro Tip: Pair with a 20–30A charger to avoid undercharging—AGM cells need full saturation to prevent sulfation.
For example, a 31M powers a 50W RV fridge for ~26 hours. Transitionally, its vibration resistance makes it reliable for rough terrain. However, always monitor depth of discharge (DoD)—keeping it above 50% extends cycle life from 500 to 1,000 cycles. Beyond mobility uses, solar setups benefit from its low self-discharge (3% monthly), reducing maintenance. But what if you need higher voltage? Series configurations require matched batteries and a compatible inverter.

How does AGM technology enhance performance?
AGM construction traps electrolyte in fiberglass mats, enabling spill-proof operation and faster recharge than flooded batteries. With 200–300A max discharge rates, it outperforms gel cells in cold cranking amps (CCA). Pro Tip: Never expose AGM batteries to temperatures above 113°F—thermal runaway risks increase.
