What the Sonnenschein GF12033YG1 is for

The Sonnenschein GF12033YG1 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 15 kg and F4 terminals.

Technology inside the Sonnenschein GF12033YG1

The GF12033YG1 is one of the Sonnenschein references for this type of use; it shares the same manufacturing and quality-control criteria as the rest of the brand's catalogue.

GEL technology fixes the acid in a solid gel. That removes maintenance and leaks and gives very long cycle life, in exchange for slightly slower recharging and lower peak current than an AGM.

Dimensions, polarity and mounting

It has external dimensions of 210 × 175 × 175 mm and weighs 15 kg. It uses F4 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.

What Sonnenschein does differently

Sonnenschein (EnerSys) invented the dryfit® GEL battery: the world reference in gel batteries for electric mobility, light traction and applications that demand safety and intensive cycling. We guarantee that every Sonnenschein arrives new, charged and with the manufacturer's full warranty.

How to make it last longer

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

Warranty and coverage

The Sonnenschein GF12033YG1 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.
