What the Sonnenschein GF12040Y is for

The Sonnenschein GF12040Y is the usual replacement in power wheelchairs, mobility scooters and light electric vehicles. Recharge after each use and avoid leaving it discharged for days. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 17.50 kg and A-Terminal terminals.

Will it fit your current battery tray?

It has external dimensions of 242 × 175 × 190 mm and weighs 17.50 kg. It uses A-Terminal terminals, the system that anchors and connects it in the vehicle. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.

Technology inside the Sonnenschein GF12040Y

Within the Sonnenschein catalogue, the GF12040Y is the 48 Ah model designed for this application.

In a GEL battery the electrolyte is gelled with silica: it is fully sealed, cannot spill and tolerates deep discharge very well. It is the preferred technology in electric mobility, marine service and heavy-cycling applications.

Care and maintenance

Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity. Use the original charger or one compatible with the battery technology (AGM/GEL) and always replace both batteries in the set together.

Official warranty

The Sonnenschein GF12040Y comes with the manufacturer's official warranty against manufacturing defects. If it fails through a defect within the warranty period, we replace it at no cost to you.
