Cyclic deep-cycle applications demand a battery that can withstand repeated discharge and recharge without degradation – the Sonnenschein GF12051Y1 is engineered precisely for this duty. Part of the GF-Y (dryfit? A500 Cyclic) range, this 12V 56Ah gel battery is designed for the leisure and mobility sector, where reliable, sustained energy delivery is critical across applications including electric boats, golf carts, powered wheelchairs, and mobility scooters.
Built on Sonnenschein's proven dryfit? technology, the GF12051Y1 uses VRLA (valve regulated lead acid) construction with the electrolyte immobilised in a gel matrix. This eliminates free acid, prevents stratification, and supports deep-cycle use rated to approximately 450 cycles. The sealed, maintenance-free design requires no electrolyte topping-up throughout its service life, and the valve-regulated construction controls internal pressure safely without venting under normal operating conditions." The battery measures 278mm (L) × 175mm (W) × 190mm (H inc. terminal) and weighs 20.8 kg. It is rated at 56Ah (C20) at 12V. Terminal type is T1 with B00 hold-down configuration and standard polarity (0). No cross-reference codes are confirmed for this SKU; buyers should verify fitment against OEM documentation.
