How does the PSoC resilience benefit commercial truck and marine users?

A1 SolarStore

PSoC (Partial State of Charge) resilience is a game-changer for real-world use. In commercial trucks, drivers often use hotel loads (TV, microwave, HVAC) overnight without fully recharging the battery before the next trip. In boats, you might run trolling motors all day without getting a full recharge between fishing sessions. Standard AGM batteries suffer from sulfation when operated this way, losing capacity quickly and failing in 1-2 years. The OverDrive AES-31's carbon additive technology prevents this sulfation, allowing it to operate in partially charged states for extended periods without damage. This means the battery maintains its 104Ah capacity and delivers its full 1,200-cycle lifespan even with irregular charging—which is exactly how trucks, RVs, and boats are actually used. You get reliable performance without babying the battery or following strict charging protocols.PSoC (Partial State of Charge) resilience is a game-changer for real-world use.

Can this battery be used for both starting and deep-cycle applications?

A1 SolarStore

Yes, the OverDrive AES-31 is a dual-purpose battery that excels at both. With 540 Cold Cranking Amps (CCA), it provides reliable engine starting power, while its 104Ah capacity and 1,200-cycle rating make it excellent for deep-cycle house loads. This makes it perfect for commercial trucks with sleeper cabs (starting the engine + powering appliances), RVs (starting + running lights, fans, water pumps), and boats (starting + trolling motors and electronics). Unlike traditional batteries that compromise performance when trying to do both jobs, the OverDrive's AES technology maintains strong performance in both roles, eliminating the need for separate starting and house batteries in many applications.

What makes the OverDrive series different from the Solar SAES or Motive series?

A1 SolarStore

While all use Trojan's AES technology with 3x cycle life and PSoC resilience, each series is optimized for different applications. The OverDrive series includes starting capability (540 CCA) and is designed for transportation, marine, and RV use where you need both engine starting and deep-cycle power. The Solar SAES series (like SAES-12-105, SAES-12-205) is optimized purely for deep-cycle solar storage with no starting capability. The Motive series (24-AES, J185-AES, L16-AES) is designed for industrial equipment like floor scrubbers and forklifts. Choose OverDrive if you need a dual-purpose battery for vehicles or boats. Choose Solar SAES for stationary solar systems. Choose Motive for industrial equipment.

About product

Trojan OverDrive™ AES-31 Deep-Cycle Battery

Heavy-Duty Power for Transportation, Marine & High-Demand Applications

The Trojan OverDrive™ AES-31 is a 12V deep-cycle battery specifically engineered for heavy-duty transportation and high-demand marine/RV applications. Part of Trojan's Advanced Energy Storage (AES) line, the OverDrive series utilizes specialized carbon additive technology to overcome the traditional weaknesses of standard AGM batteries, particularly in Partial State of Charge (PSoC) conditions where conventional batteries fail prematurely.

Ideal For

Heavy-Duty Transportation – Engineered to handle high electrical loads in commercial trucks and sleeper cabs, powering liftgates and hoteling loads reliably
Marine & RV Applications – High-performance "house" battery for sailing, trolling motors, and motorhomes with frequent deep discharge cycles
Renewable Energy Systems – Powers remote solar installations, street lights, and micro-grids where solar input may be inconsistent
Industrial Equipment – Reliable power for floor scrubbers and material handling equipment requiring long runtimes and quick recovery

Superior Performance Features

✓ 3x the Life of Standard AGM – Validated to deliver 1,200 cycles at 100% Depth of Discharge, compared to ~400 cycles typical of standard AGM batteries

✓ PSoC Resilience – Unlike conventional lead-acid batteries, designed to operate in partial state of charge without suffering from sulfation-induced premature failure

✓ Extreme Temperature Tolerance – Operates effectively in harsh environments from -40°F to 140°F (-40°C to 60°C)

✓ Maintenance-Free & Sealed – Non-spillable VRLA design requires no watering and can be safely mounted horizontally in tight compartments
