Advanced Energy Storage (AES) Technology

PSoC (Partial State of Charge) Tolerance Designed to handle Partial State of Charge operation, preventing internal damage that occurs when batteries aren't recharged to 100% daily. Revolutionary for solar systems and applications with inconsistent charging patterns where conventional batteries fail rapidly.

Extreme Longevity - 1,200 Cycle Rating Rated for up to 1,200 cycles at 100% Depth of Discharge—approximately triple the lifespan of standard AGM batteries. Delivers exceptional long-term value despite premium initial investment.

Temperature Resilience Maintains performance in extreme environments ranging from -40°F to 140°F (-40°C to 60°C). Suitable for applications where temperature extremes would destroy conventional batteries.

Maintenance-Free AGM Construction Completely sealed design requires zero watering and eliminates all routine maintenance. Absorbed Glass Mat technology allows flexible mounting positions including horizontal installation.

Non-Spillable & Vibration-Resistant AGM construction absorbs electrolyte in glass mat separators, preventing spills even if case is damaged. Superior vibration resistance ideal for mobile equipment and demanding industrial environments.

M8 Threaded Terminal Connections 8mm threaded insert terminals provide secure, vibration-proof connections with low electrical resistance. Professional installation with consistent torque specifications ensures reliable performance.

Why Choose the 31-AES?

The 31-AES represents premium maintenance-free deep-cycle performance in the versatile Group 31 format. AES technology delivers revolutionary PSoC tolerance—thriving in applications where inconsistent charging destroys conventional batteries. With 1,200-cycle longevity (3x standard AGM), extreme temperature capability (-40°F to 140°F), and zero maintenance requirements, the 31-AES provides superior total cost of ownership. For solar installations, heavy-duty industrial equipment, trucking auxiliary power, and professional applications where reliability and longevity justify premium investment, the 31-AES delivers unmatched value.

31-AES vs. Flooded Batteries

The 31-AES offers 102Ah maintenance-free AGM capacity with zero watering requirements, PSoC resilience, non-spillable construction, and 1,200-cycle life rating. Flooded batteries require regular watering, must remain upright, struggle in partial charge conditions, and typically last 400-500 cycles. AGM design allows flexible mounting orientations and operates in extreme temperatures from -40°F to 140°F. Choose 31-AES for maintenance-free operation, inconsistent charging applications (solar, auxiliary power), extreme environments, or installations where battery access is difficult. Select flooded alternatives only when lower initial cost outweighs maintenance burden and PSoC limitations.

Shipping & Installation Considerations

Weight & Handling: At approximately 69 lbs per battery, proper lifting techniques and equipment are essential. Professional installation recommended for safe handling and proper connection of M8 terminals.

Freight Coordination: Substantial weight requires careful delivery planning and coordination to avoid costly redelivery charges. Clear communication of delivery requirements essential.

AGM Charger Required: Verify charging equipment has AGM-specific settings. Using flooded battery charger profiles will damage AGM batteries. Professional installation ensures proper charger configuration.
