Maximum performance for rehabilitation and leisure applications

The Sonnenschein GF 12 052 Y is the specialist for mobile, electric-powered vehicles in the rehabilitation and leisure sector. Its main areas of use are electric wheelchairs, scooters for seniors, golf caddies, and mobile lifting systems. Wherever vehicles need to operate reliably and maintenance-free every day, this battery delivers the necessary energy and endurance.

Proven Dryfit® gel technology

The Dryfit® gel technology invented and perfected by Sonnenschein binds the electrolyte in a thixotropic silica gel. This makes the battery not only absolutely leak-proof and installable in any position, but also provides excellent cycle stability and very low self-discharge. In contrast to conventional wet batteries, acid stratification is prevented, significantly extending service life in tough cycling operation.

Developed for durability and cost-effectiveness

The GF-Y series has been designed for maximum economy and minimum downtime in professional use. The high cycle life reduces the need for premature replacement and thus lowers the total cost of ownership (TCO) of your equipment. Absolute maintenance freedom eliminates the time and cost involved in regularly refilling water and ensures the highest level of occupational safety.

FAQs about the Sonnenschein GF 12 052 Y lead-gel battery

What does "traction battery" mean?

A traction battery (or drive battery) is specially designed to supply electric motors with energy over a longer period of time. It is extremely cycle-stable, meaning that it can be regularly deeply discharged and recharged, as is the case with daily use in, for example, electric wheelchairs. This differentiates it from a starter battery.

What is the main advantage of Dryfit® gel technology in mobile use?

The crucial advantage is absolute maintenance freedom. In mobile devices, the time-consuming and error-prone checking and refilling of water is eliminated. Furthermore, the batteries are leak-proof, even when tilted or exposed to strong vibrations, which significantly increases operational safety in mobile use.

What do the capacity specifications C5 and C20 mean?

The capacity of a battery depends on how quickly it is discharged. The C-rate indicates the discharge current. C5 (discharge over 5 hours) is the standard for traction applications because high currents flow here. C20 (discharge over 20 hours) is a common comparative value, with the nominal capacity being higher.

How must this lead battery be disposed of?

Lead batteries contain environmentally harmful substances and must not be disposed of in household waste. You can return your old battery free of charge to any retailer who sells new batteries or at municipal recycling centres to ensure proper recycling.
