Mobility battery Sonnenschein GF12065Y 78Ah 12V

Its 353 × 175 × 190 mm make it the exact replacement for the 78 Ah battery fitted as standard to many power wheelchairs and mobility scooters.

• Sealed AGM/GEL: safe indoors and in transport.
• GEL: excellent resistance to deep discharge and long cycle life.
• Approved for air and sea transport (VRLA).
• No maintenance, no water top-ups.

What the Sonnenschein GF12065Y is for

The Sonnenschein GF12065Y is designed for power wheelchairs, mobility scooters and light electric vehicles. Wheelchairs and scooters normally use two identical batteries in series: replace them together. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 27 kg and AP terminals.

Size, terminals and hold-down of the Sonnenschein GF12065Y

In terms of format, the Sonnenschein GF12065Y measures 353 × 175 × 190 mm (length × width × height) and weighs 27 kg. It uses AP terminals, the system that anchors and connects it in the vehicle. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters.
