Maximum performance for rehab and leisure applications

The Sonnenschein GF 12 051 Y1 is the specialist for mobile, electrically driven vehicles in the rehabilitation and leisure sector. Its main fields of application include electric wheelchairs, scooters for seniors, golf caddies, and mobile lifting systems. Wherever vehicles need to operate reliably and maintenance-free on a daily basis, this battery provides the required energy and stamina.

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 completely leak-proof and installable in any orientation, but also ensures excellent cycle stability and very low self-discharge. In contrast to conventional wet batteries, acid stratification is prevented, significantly prolonging service life in heavy cycling use.

Designed for longevity and economy

The GF-Y series was developed for maximum cost-efficiency and minimal 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 devices. The complete freedom from maintenance eliminates the time and cost for regular water refilling and provides the highest occupational safety.

FAQs on the Sonnenschein GF 12 051 Y1 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. It is extremely cycle-resistant, that is, it can be deeply discharged and recharged regularly, which is the case for everyday use, e.g., 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 complete maintenance freedom. For mobile devices, time-consuming and error-prone checking and topping up of water is eliminated. In addition, the batteries are leak-proof, even when tilted or subject to strong vibrations, which greatly 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, as there high currents are drawn. C20 (discharge over 20 hours) is a common comparative value, where the specified nominal capacity is higher.

How must this lead battery be disposed of?

Lead batteries contain environmentally hazardous substances and must not be disposed of with household waste. You can return your old battery free of charge to any dealer selling new batteries or at municipal recycling centres to ensure proper recycling.
