The Gruber 58EGPS-12-35-P is a high-capacity 12V 35Ah AGM (VRLA) battery engineered for power wheelchairs, mobility scooters, patient lifts, medical carts, and other equipment where dependable runtime and consistent power delivery are essential. Its combination of substantial energy capacity, low internal resistance, and rugged sealed construction makes it well suited for repeated discharge and recharge cycles as well as demanding backup-power applications.
Most 24V power wheelchairs and mobility scooters use two 12V batteries connected in series, while some 36V and 48V systems use three or four batteries. With its compact U1-style footprint and T6 bolt-on terminals, this battery fits many mobility applications originally equipped with 33Ah, 34Ah, 35Ah, or similarly sized AGM batteries.
Advanced Absorbent Glass Mat (AGM) technology securely retains the electrolyte within the separator material, creating a sealed, maintenance-free, non-spillable battery. The design provides reliable cyclic performance while maintaining strong high-rate output for acceleration, inclines, motor startup, and other conditions that place heavier electrical demands on the battery.
