Maximum performance for rehab and leisure applications

The Sonnenschein GF 12 040 Y is the specialist for mobile, electrically powered vehicles in the rehabilitation and leisure sector. Its main areas of application are electric wheelchairs, scooters for seniors, golf caddies, mobile lifting systems and electric boats. 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.

Developed for durability and cost-effectiveness

The GF-Y series was developed for maximum cost-effectiveness and minimal downtime in professional use. The high cycle life reduces the need for premature replacement and thus lowers the total operating costs (TCO) of your devices. The absolute maintenance-free operation eliminates the time and cost required for regular topping up with water and ensures the highest level of occupational safety.

FAQs about the Sonnenschein GF 12 040 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 longer period of time. It is extremely cycle-resistant, i.e. it can regularly be deeply discharged and recharged, which is the case in the daily use of, for example, electric wheelchairs. This distinguishes it from a starter battery.

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

The main advantage is the absolute maintenance-free operation. With mobile devices, the time-consuming and error-prone checking and topping up of water is not required. In addition, these batteries are leak-proof, even when tilted or exposed to severe 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, as high currents flow here. C20 (discharge over 20 hours) is a common comparison value, where the nominal capacity is higher.

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