Why Terra Supreme
Forget almost everything you think you know about Group 31 lead-acid batteries. With over 30 years in the industry—bringing advanced battery monitoring to market, launching AGM technology, and delivering mission-critical systems for emergency services and the military—We can say with confidence that traditional assumptions simply don’t apply here.
Externally, Terra’s battery is designed to drop-in like a conventional unit, requiring no charging system changes and allowing easy series or parallel configurations. Internally, it’s entirely different: horizontally oriented plates, no internal busbars, and an embedded Bluetooth monitor that delivers real-time battery data.
A NEW Standard for G31 Batteries!
Designed for both high-power engine starting and deep-cycle use, Terra Supreme Batteries deliver the strongest cranking performance in its Group 31 class, surpassing both AGM and lithium competitors in CCA, MCA, and PHCA output. With 240 minutes of reserve capacity and 4,000 cycles at 60% depth of discharge, it exceeds lead-acid longevity and matches lithium-level durability under comparable conditions.
Bipolar Lead-Acid Offers:
- Higher Power/Energy Density: More efficient current path, more active material utilization, lighter weight.
- Deeper Discharge: Can handle partial state-of-charge better than traditional lead-acid.
- Longer Life: Improved performance often leads to longer lifespan.
- Higher Efficiency: Bipolar design offers more direct electron flow, improving power.
- Less Weight: Bipolar batteries are significantly lighter due to integrated plates.
- More Usable Capacity: Bipolar handles deeper discharges better than standard lead-acid.
- Better Cost vs. Performance: Bipolar aims for lithium-like performance (lightweight, deep cycle) at a lower manufacturing cost than lithium, but higher than traditional lead-acid.
Key Battery Features
High Energy Output
Compared with conventional AGM batteries TSB’s higher energy density (15-30% increase) provides longer run times with lighter batteries.
Built-In BMS
Equipped with a Battery Monitoring System that monitors overcharge, over-discharge, over-current, short circuits, and high temperatures. It also features bluetooth communication of battery condition with owner-operator.
Direct Group 31 Drop-In
Directly replace heavier, less powerful lead-acid batteries for superior performance. Often up to 70% lighter, longer life (4000+ cycles), and faster charging.
Advanced Composite Materials
Pure lead reinforced with glass fiber 10x stronger than steel is used to fabricate dimensionally stable composite grids. Such material eliminates active material shedding.
5-Year Warranty
Limited 5-year replacement period from start-of-use date. Covers defects in materials and workmanship, with proof of purchase and proper charging mechanisms. *See owners Warranty.
