When it comes to dependable power storage for heavy-duty vehicles, RVs, marine equipment, and off-grid energy systems, the Group 31 battery is one of the industry's most trusted sizes. Known for its excellent capacity and rugged construction, it comes in several chemistries: FLA, AGM, Gel, and LiFePO4.
A Group 31 battery is a standardized size established by the Battery Council International (BCI). The designation refers to physical dimensions, terminal configuration, and general performance characteristics rather than internal chemistry.
Because of their large capacity and robust construction, Group 31 batteries deliver reliable starting power while supporting deep-cycle operation, making them exceptionally versatile across diverse industries.
Traditional and most affordable option. Contains liquid electrolyte and requires regular maintenance.
Seals electrolyte inside fiberglass mats, creating a durable, maintenance-free design.
Suspends electrolyte in silica gel. Ideal for deep discharge and extreme vibration environment.
Lightweight technology with integrated Battery Management System (BMS) for protection against extreme temp, short circuits, and overcharging.
