Trojan Solar SAES-12-135 135Ah 12V AGM Battery

Reliable 12V Energy Storage for Off-Grid Living and Critical Backup Power

The Trojan Solar SAES-12-135 delivers maintenance-free reliability for renewable energy systems and off-grid applications where standard batteries fall short. This 135Ah 12V battery combines Advanced Energy Storage (AES) technology with rugged construction to provide dependable power in the challenging conditions that define real-world solar and backup power systems.

Engineered for Irregular Charging Patterns

Advanced Energy Storage Technology

Unlike conventional batteries that degrade rapidly when left partially charged, the SAES-12-135 thrives in Partial State of Charge (PSoC) conditions. Cloudy weather that prevents full daily recharging won't damage this battery—it's specifically designed to handle the irregular charging cycles that destroy standard lead-acid batteries. This resilience is critical for off-grid solar systems, remote installations, and backup power applications where perfect charging conditions aren't guaranteed.

Proven Longevity

With validation for 1,200 cycles at 100% depth of discharge, this battery delivers triple the lifespan of standard deep-cycle AGM batteries. That translates to years of dependable service in applications where battery replacement is inconvenient, expensive, or simply impractical.

Built for Demanding Environments

• 1,200 cycles at 100% DOD — 3x longer lifespan than standard AGM batteries
• Extreme temperature tolerance (-40°F to 140°F) for harsh outdoor installations
• Completely maintenance-free — sealed VRLA design requires zero watering
• Vibration-resistant construction — safe for mobile and remote applications
• Non-spillable design — horizontal mounting capability for flexible installation

Where the SAES-12-135 Excels

Off-Grid Solar Systems

Power remote cabins, tiny homes, and residential solar installations with confidence. The SAES-12-135 stores daytime solar energy to power lights, electronics, and appliances throughout the night, handling the deep discharge cycles that off-grid living demands. The 135Ah capacity at 12V provides 1.62kWh of energy storage—substantial power for small to medium off-grid applications.

Remote Monitoring & Infrastructure

Telecommunications towers, oil and gas monitoring equipment, solar-powered traffic signals, and remote data collection systems depend on batteries that operate reliably between infrequent service visits. The SAES-12-135's partial charge tolerance and extreme temperature resilience ensure continuous operation in locations where maintenance is difficult or expensive.

Emergency Backup Power

Keep critical systems running during grid outages. The SAES-12-135 serves as a dependable UPS (Uninterruptible Power Supply) for home internet, security systems, emergency lighting, and essential medical equipment. Its partial charge tolerance means the battery stays healthy even during extended periods between power failures, ensuring readiness when you need it most.

Marine & RV House Banks

Serious cruisers and off-grid RVers demand maintenance-free reliability. The sealed AGM construction eliminates gassing concerns in living spaces, while the non-spillable design allows safe operation during travel. The 135Ah capacity provides ample house power for extended adventures—running refrigeration, electronics, lighting, and entertainment systems without constant recharging.

Premium Features, Professional Results

The 12V configuration simplifies system design for applications requiring standard 12V power or 24V systems (using two batteries in series). This versatility makes the SAES-12-135 ideal for retrofitting existing 12V systems or building new installations where simplicity and compatibility matter.

As a sealed Valve Regulated Lead Acid (VRLA) battery, the SAES-12-135 requires absolutely no maintenance. No watering schedules, no acid spills, no electrolyte monitoring—just reliable, consistent performance year after year. The vibration-resistant construction ensures durability in mobile applications like RVs and boats, as well as remote installations subject to environmental stress.

The extreme temperature tolerance (-40°F to 140°F) makes this battery suitable for uninsulated outdoor battery enclosures, from arctic research stations to desert solar installations, powering equipment in conditions that would cripple conventional batteries.

The Smart Choice for 12V Systems

The Trojan Solar SAES-12-135 is your worry-free solution for reliable 12V power. Whether you're building an off-grid homestead, equipping a remote monitoring station, backing up critical infrastructure, or powering mobile living spaces, this battery delivers the resilience and longevity your application demands at a voltage that simplifies system design.
