Trojan Motive 31-AES DT 102Ah 12V AGM Deep Cycle Marine, RV & Floor Scrubber Battery

Trojan's 31-AES DT features proprietary Advanced Energy Storage (AES) technology delivering up to 3x the cycle life of standard AGM batteries—validated at 1,200 cycles at 100% depth of discharge versus 400 cycles for conventional AGM. This compact 12V 102Ah maintenance-free sealed AGM battery is specifically engineered for demanding motive power and auxiliary applications requiring reliable deep-cycle performance in the popular BCI Group 31 footprint. The "DT" designation indicates Dual Terminal configuration with M8 terminals for flexible connection options and secure high-current delivery in commercial equipment and marine systems. It excels in Partial State of Charge (PSoC) conditions when irregular charging patterns prevent full daily recharging—the reality of floor scrubbers, boats, RVs, and solar installations. The sealed VRLA AGM construction requires zero maintenance—no watering, no hassle—making it ideal for marine vessels, recreational vehicles, and commercial equipment where service access is impractical. Its non-spillable design allows horizontal or vertical mounting in confined spaces and meets regulatory requirements for airports, healthcare facilities, shopping centers, and educational institutions. The rugged polypropylene case provides superior impact, shock, and vibration resistance for mobile equipment, while low internal resistance (4.8 mΩ) delivers higher discharge current and charging efficiency. With operating temperature range from -40°F to 140°F and proven AES chemistry optimized for daily deep cycling, the 31-AES DT delivers maximum energy storage, extended cycle life, and proven reliability for floor scrubbers, marine house banks, RVs, aerial lifts, golf carts, telecommunications, and off-grid solar systems requiring compact 12V deep-cycle capability with minimal maintenance.
