Maximum performance for rehab and leisure applications

The Sonnenschein GF 12 051 YG1 is the specialist for mobile, electrically powered vehicles in the rehabilitation and leisure sector. Its main areas of application are electric wheelchairs, scooters for senior citizens, golf caddies and mobile lifting systems. Wherever vehicles need to work reliably and maintenance-free on a daily basis, this battery provides 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 not only makes the battery absolutely leak-proof and installable in any position, but also ensures excellent cycle stability and very low self-discharge. In contrast to conventional wet batteries, acid stratification is prevented, which considerably extends the service life in hard cycling operation.

H2: Developed for longevity and economy

The GF-Y series was developed for maximum economy and minimum downtime in professional use. The long cycle life reduces the need for premature replacement and therefore lowers the total cost of ownership (TCO) of your devices. Completely maintenance-free, it eliminates the time and expense of regular water refilling and ensures maximum work safety.

FAQs about the Sonnenschein GF 12 051 YG1 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 long period of time. It is extremely cycle-resistant, i.e. it can be regularly deeply discharged and recharged, which is the case with daily use, for example in electric wheelchairs. This distinguishes it from a starter battery.

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

The decisive advantage is the absolute maintenance-free operation. In mobile devices, time-consuming and error-prone checking and topping up of water is no longer necessary. In addition, the batteries are leak-proof, even when tilted or subjected to heavy vibrations, which significantly increases operational safety when used in mobile applications.

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, as high currents flow here. C20 (discharge over 20 hours) is a common comparative value, where the nominal capacity is higher.

How should 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 dealer who sells new batteries or to municipal recycling centres to ensure proper recycling.
