Maximum performance for rehab and leisure applications

The Sonnenschein GF 12 072 Y is the specialist for mobile, electrically powered vehicles in the rehab and leisure sector. Its main areas of application are electric wheelchairs, scooters for seniors, golf caddies, mobile lifting systems and small cleaning machines. Wherever vehicles must work reliably and maintenance-free on a daily basis, this battery delivers the required energy and endurance.

Proven Dryfit® Gel Technology

The Dryfit® Gel technology invented and perfected by Sonnenschein binds the electrolyte within a thixotropic silica gel. This makes the battery absolutely leak-proof and installable in any position, as well as ensuring excellent cycle resistance and very low self-discharge. Unlike conventional wet batteries, acid stratification is prevented, which significantly extends the service life in tough cycling operation.

Developed for longevity and economy

The GF-Y series has been developed for maximum economy and minimal downtime in professional use. The long cycle life reduces the need for premature replacement and thus lowers the total cost of ownership (TCO) of your devices. The absolute maintenance-free design eliminates the time and cost for regular water refilling and ensures maximum operational safety.

FAQs about the Sonnenschein GF 12 072 Y lead-gel battery

What does "traction battery" mean?

A traction battery (or drive battery) is specifically designed to supply electric motors with energy over a long period of time. It is extremely cycle-resistant, meaning it can be regularly deeply discharged and recharged, as is the case with daily use such as electric wheelchairs. This distinguishes it from a starter battery.

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

The key advantage is its absolute maintenance-free design. With mobile devices, the time-consuming and error-prone checking and refilling of water is eliminated. In addition, the batteries are leak-proof even when tilted or exposed 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 high currents flow here. C20 (discharge over 20 hours) is a common comparative value in which the rated capacity is higher.

How should this lead battery be disposed of?

Lead batteries contain environmentally harmful substances and must not be disposed of with 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.
