What the Sonnenschein GF12033YG2 is for
The Sonnenschein GF12033YG2 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 14.60 kg and G-M6 terminals.
Technology inside the Sonnenschein GF12033YG2
Within the Sonnenschein catalogue, the GF12033YG2 is the 38 Ah model designed for this application.
A GEL battery is the choice when cycle resistance and safety matter most: no gases, no liquid and thousands of partial discharges in its lifetime.
Will it fit your current battery tray?
The Sonnenschein GF12033YG2 is made in the 210 × 175 × 175 mm format and weighs 14.60 kg. It uses G-M6 terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.
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.
Care and maintenance
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 GF12033YG2 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.
Shipping, delivery and returns
Order before 6:00 pm with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have 14 days to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email.

Frequently asked questions
Is the Sonnenschein GF12033YG2 a GEL battery? What is GEL used for?
Yes, this model is a GEL battery: sealed lead-acid where the electrolyte is in gel form. It tolerates deep discharges very well and is ideal for cyclic use (solar, motorhomes, electric wheelchairs, motorcycles). Requires a GEL-specific smart charger — max charge voltage ~14.1 V (vs 14.4-14.7 V for AGM). Lifespan 6-10 years.
How do I fit the GF12033YG2 model in my device?
In most devices it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on our blog. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On devices with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.
How long does the Sonnenschein GF12033YG2 battery last?
Expected lifespan of the Sonnenschein GF12033YG2 is 6 to 10 years in cyclic use (marine, caravan, solar) with controlled discharges. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured.
What are the dimensions of the Sonnenschein GF12033YG2 battery?
Dimensions (length × width × height) are 210×175×175 mm — also written as 210x175x175 mm and correspond to the European LB1 case size — following the European DIN standard. Always measure the space in your device before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.
What are the equivalents of the GF12033YG2 model?
Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop devices. See the "Equivalents" section to view recommended options at the same performance level.
