Trojan OverDrive AES-31 104Ah 12V AGM Deep-Cycle Battery for Trucks, Marine & RV Auxiliary Power

Trojan OverDrive AES‑31 is a premium 12V 104Ah AGM deep‑cycle battery designed for demanding auxiliary power and motive applications. It delivers reliable, long‑duration power for vehicles and equipment that frequently operate under deep‑cycle and partial state of charge conditions, making it ideal where standard batteries fail prematurely.

Product overview

Trojan’s OverDrive AES‑31 combines Advanced Energy Storage (AES) technology with rugged AGM construction to provide exceptional cycle life, strong PSoC tolerance, and stable voltage under heavy loads. This maintenance‑free, sealed design is optimized for applications that require consistent, deep‑cycle performance in harsh environments with vibration and temperature extremes.

Key applications

• Trucking sleeper cabs and hotel loads powering HVAC, inverters, and onboard electronics while the engine is off.
• Commercial vehicles and auxiliary power systems that rely on deep‑cycle batteries for lifts, pumps, and work lights.
• Marine house banks supporting navigation, lighting, and comfort loads on boats and yachts.
• RV house systems providing off‑grid power for appliances, lighting, and electronics in motorhomes and camper vans.

Design & construction

• Advanced AGM deep‑cycle design engineered for repeated deep discharges and rapid recovery.
• AES technology improves tolerance to partial state of charge use, reducing damage when full recharge is not always possible.
• Sealed, non‑spillable construction with high vibration resistance for reliable performance in mobile and harsh operating conditions.
