Heavy-Duty & Commercial Vehicles
- The Terra Supreme Group 31 batteries are a standard, widely accepted battery size in commercial trucking due to their balance of size, power, and compatibility with truck electrical systems. They are a one-to-one drop-in for semi-trucks, delivery vehicles, and fleets.
- Our bi-polar Group 31 battery focuses on a premium segment of that established market because fleets already trust Group 31 as a baseline battery choice.
Performance & Reliability Improvements
Our group 31 batteries have characteristics trucking operations value. Terra Supreme bi-polar battery architecture can deliver these robust for truck applications vs. traditional lead-acid cells:
- High cold-cranking amps (CCA) — reliable starting power for large diesel engines even in cold climates.
- High reserve capacity — they can power auxiliary systems while engines are off.
- Vibration resistance & durability — essential for trucks on the road.
These traits directly address uptime and reliability — two core purchasing criteria for fleets.
Compatibility with Electric & Hybrid Trucks
- While heavy electric trucks typically use large traction battery packs for propulsion, Terra Supreme Group 31 batteries still remain important for auxiliary 12V / 24V power (lighting, control systems, HVAC, infotainment, telematics).
- Our Group 31 designs that offer better cycle life and charge acceptance are especially compelling for electric trucks’ accessory power, where reliability matters as much as in diesel vehicles.
- Safer and easier to manufacture, the lower upfront cost than lithium-ion offers improved performance over conventional lead-acid.
