Trojan Solar SAES-12-105 LT 107Ah 12V AGM Deep Cycle Off-Grid Solar & Backup Power Battery

Trojan's Solar SAES-12-105 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. The "S" in SAES stands for Solar—this compact 12V 107Ah maintenance-free sealed AGM battery is specifically engineered to handle the unpredictable charging patterns that solar and wind systems create. It excels in Partial State of Charge (PSoC) conditions when cloudy weather prevents full daily recharging or when systems experience deep overnight discharges—the daily reality of solar installations. The sealed VRLA AGM construction requires zero maintenance—no watering, no hassle—making it ideal for remote off-grid installations where service access is impractical. Its non-spillable design allows horizontal mounting in challenging locations and confined spaces, while the compact BCI Group 31 footprint (12.80" × 6.81" × 9.34") fits standard solar battery enclosures and equipment. The rugged design absorbs vibration and shock for reliable operation in harsh environments, and with low internal resistance (1.28 mΩ) for superior charge acceptance and energy transfer, the SAES-12-105 provides 1.26 kWh energy storage with proven reliability. Operating from -40°F to 140°F and backed by IEC 61427 certification with 8 year life rating, this battery delivers maximum energy storage, extended cycle life, and proven reliability for residential off-grid solar systems, commercial renewable energy storage, backup power systems, rural electrification, unreliable grid applications, marine vessels, RVs, and telecommunications requiring compact 12V deep-cycle capability with minimal maintenance.
