## Quick description

**Sonnenschein GF12052YO 12V 60Ah** is a deep-cycle battery optimised for repeated discharges down to 80 % DOD and thousands of life cycles. Ideal when the battery discharges and recharges daily rather than just cranking the engine (mobility scooters, backup systems, golf, pallet trucks).

## Why this deep-cycle battery?

- **Daily cycling without wear** handles deep discharges without losing capacity
- **Sealed AGM/GEL** no maintenance, no risk of spills
- **Thousands of useful cycles** over its full lifetime

The **12 V**, **60 Ah** **Sonnenschein GF12052YO** with GEL technology is the standard replacement for power wheelchairs, mobility scooters and light electric vehicles. It replaces the original battery without adaptation in power wheelchairs and mobility scooters with a 261 × 170 × 178 mm format: same 60 Ah capacity.
- Thousands of useful cycles over its lifetime.
- Standard replacement format for wheelchairs and scooters.
- GEL technology: gelled electrolyte, fully sealed and maintenance-free.
- Designed to be discharged and recharged daily without losing capacity.

### Will it fit your current battery tray?

In terms of format, the Sonnenschein GF12052YO measures 261 × 170 × 178 mm (length × width × height) and weighs 20 kg. It uses 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 the Sonnenschein GF12052YO is for

The Sonnenschein GF12052YO 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 20 kg and M6 terminals.

### Technology inside the Sonnenschein GF12052YO

Within the Sonnenschein catalogue, the GF12052YO is the 60 Ah model designed for this application.
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.

### Sonnenschein: the maker behind the GF12052YO

Sonnenschein batteries with dryfit® technology have equipped power wheelchairs, cleaning machines and industrial vehicles for decades thanks to their reliability and cycle life. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

### Warranty and coverage

The Sonnenschein GF12052YO 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.

### Usage and maintenance tips

GEL batteries need lower charging voltages: always use a charger with a GEL mode so as not to damage the electrolyte. Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity.

### Delivery times and returns

Orders placed **before 6:00 pm** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have **14 days** to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships.

## Frequently asked questions

### Is the Sonnenschein GF12052YO 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 GF12052YO 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 many years does this battery last?

Expected lifespan of the Sonnenschein GF12052YO 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 GF12052YO battery?

Dimensions (length × width × height) are 261×170×178 mm — also written as 261x170x178 mm — 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 GF12052YO 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.
