Trojan T-105 6V 225Ah Battery Pack of 4 for Golf Cart (4x6V)
Swapped these into my club car last week and the difference is night and day. The cart has way more pep on the hills now. Trojan really is the gold standard for a reason.

They aren't the top-of-the-line Signature series, but for the money, you can't beat them.

Bought these for my off-grid cabin solar bank and they've been working great so far. They're a more budget-friendly version of the standard T-105s but still seem to have that Trojan build quality. Very happy with the runtime.

These Gel units are perfect since they don't leak and I don't have to worry about maintenance. They’ve been reliable through daily charging for three months now.

Have a 48V solar array using these 8-volters and the internal resistance is consistently low across the string. They handle the summer heat here in Arizona surprisingly well.

make sure you have the height clearance in your battery box before buying! though they’re intended for industrial stuff, the capacity gives me way more boondocking time than the standard group 24s

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 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.

Technical specifications
