Trojan Motive J305-DT-AES 6V 279Ah AGM Dual Terminal Battery Automotive Post + Stud

Trojan Motive J305-DT-AES 279Ah 6V AGM Deep Cycle Battery - Dual Terminal

Maximum Capacity. Dual Terminals. Zero Maintenance.

The Trojan J305-DT-AES combines heavy-duty industrial performance with unmatched connection flexibility. This premium 6V 279Ah AGM deep-cycle battery features exclusive Dual Terminal (DT) design—offering both automotive posts and threaded studs on the same battery—plus Advanced Energy Storage (AES) technology for up to three times the cycle life of standard AGM batteries.

Dual Terminal Advantage

The innovative DT (Dual Terminal) configuration provides both automotive-style posts and M8 threaded studs, giving you maximum flexibility for connecting different types of equipment, accessories, and charging systems without adapters or modifications.

Perfect for applications requiring:

• Multiple connection types on the same battery
• Standard automotive-style battery cables (top post)
• Ring terminal connections (threaded stud)
• Mixed equipment types (OEM aftermarket accessories)
• Easy integration with existing systems

Engineered for Extreme Performance

Designed for heavy-duty industrial and commercial applications where maintenance is impractical and downtime is costly, the J305-DT-AES delivers uncompromising reliability in the most demanding environments.

Ideal Applications

Industrial Floor Cleaning Equipment Powers ride-on scrubbers, sweepers, and burnishers through extended shifts with high energy density and exceptional daily cycling capability.

Aerial Work Platforms (AWP) The trusted choice for scissor lifts and boom lifts operating in harsh environments where reliability is critical for safety and productivity.

Marine & RV House Power The Dual Terminal design is especially popular in marine and RV applications, allowing easy connection of standard battery cables alongside smaller electronic accessories and charging systems.

Material Handling Equipment Provides dependable energy for electric pallet jacks, order pickers, and small industrial vehicles in warehouse and distribution operations.

Renewable Energy Storage Robust battery bank solution for off-grid solar systems and residential backup power requiring maintenance-free, long-life performance.

Advanced Energy Storage Technology

Triple the Cycle Life Validated to deliver up to 1,200 cycles at 100% depth of discharge—three times longer than standard AGM batteries, dramatically reducing replacement costs and downtime.

Partial State of Charge (PSoC) Resilience Unlike conventional lead-acid batteries that degrade without full recharging, AES technology withstands frequent partial charging without capacity loss—ideal for opportunity charging and variable-use applications.

Extreme Temperature Performance Maintains consistent performance from -40°F to 140°F (-40°C to 60°C), operating reliably in freezing warehouses, hot outdoor environments, and everything in between.

Maintenance-Free Operation Sealed VRLA AGM design eliminates all watering, acid checks, and electrolyte monitoring—reducing labor costs while ensuring peak performance.

Flexible Installation Non-spillable construction allows safe mounting in any position, including horizontal installation in tight compartments where vertical space is limited.

Maximum Capacity With 279Ah at the 20-hour rate, the J305-DT-AES provides extended runtime and maximum energy storage in the proven BCI Group 902/J305 footprint.

Why Choose Dual Terminal (DT)?

Connection Versatility:

• ✅ Automotive posts for standard battery cables (golf carts, floor equipment)
• ✅ Threaded studs for ring terminal connections (solar, marine, accessories)
• ✅ Both terminals on same battery - no adapters needed
• ✅ Easy integration with mixed equipment types
• ✅ Future-proof - accommodates different connection needs

Especially Valuable For:

• Marine installations (house bank accessories charging)
• RV systems (inverter solar 12V accessories)
• Modified equipment (OEM aftermarket components)
• Solar systems (battery cables bus bars monitoring)
• Mixed fleets (standardize on one battery for different equipment)

J305-DT-AES vs. Standard J305-AES

M8 Threaded Insert Only

Choose DT if: You need connection flexibility or use automotive-style cables Choose standard if: Threaded studs meet all your needs (lower cost)
