Trojan Solar SAES-12-135 LT 135Ah 12V Off-Grid Solar & Renewable Energy Battery

Trojan's SAES-12-135 features proprietary Advanced Energy Storage (AES) technology delivering up to 3x the cycle life of standard AGM batteries—validated at 1,200 cycles at 100% depth of discharge versus 400 cycles for conventional AGM. This specialized 12V maintenance-free sealed AGM solar battery provides exceptional performance in Partial State of Charge (PSoC) conditions, thriving when cloudy weather prevents full daily recharging—unlike conventional batteries that degrade rapidly when left partially charged. Its non-spillable VRLA construction allows horizontal mounting and operates in extreme temperatures from -40°F to 160°F (-40°C to 71°C). The sealed AGM design eliminates watering requirements, prevents gassing concerns in living spaces, and makes it ideal for off-grid applications where maintenance access is impractical. With 135Ah capacity (115Ah at 10-hour rate) and 1.62 kWh total energy output, the SAES-12-135 delivers proven reliability for remote solar installations, backup power systems, marine house banks, RVs, telecommunications equipment, and agricultural applications where irregular charging patterns are the norm.

Key applications

• Off-grid solar systems – primary energy storage for remote cabins, tiny homes, and residential solar installations requiring deep-cycle power throughout the night.
• Remote monitoring and telecommunications – towers, oil and gas monitoring equipment, solar-powered traffic signals, and data collection systems in locations with infrequent service access.
• Emergency backup power – UPS systems for home internet, security systems, emergency lighting, and essential medical equipment during grid outages.
• Rural electrification – residential and commercial installations providing renewable energy where grid power is unavailable or unreliable.
• Marine house banks – deep-cycle power for boats and yachts requiring sealed, non-spillable batteries in living spaces.
• RV and motorhome systems – house power for refrigeration, electronics, lighting, and entertainment during extended off-grid adventures.
• Agricultural equipment – remote farm installations and equipment requiring reliable solar-powered operation.
• Remote industrial sites – monitoring equipment, pumping systems, and installations requiring dependable renewable energy storage.
