Maximum Performance for Rehabilitation and Leisure Applications

The Sonnenschein GF 12 033 Y1 is the expert for mobile, electric-powered vehicles in rehabilitation and leisure. Its main applications are 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 supplies 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 absolutely leak-proof and usable in any position, and also assures excellent cycle stability and very low self-discharge. Unlike conventional wet batteries, acid stratification is prevented, which significantly extends service life under heavy cycling use.

Engineered for Longevity and Cost Efficiency

The GF-Y series was designed for maximum cost effectiveness and minimal downtime in professional applications. Its long cycle life reduces the need for premature replacement, thereby lowering the total cost of ownership (TCO) of your equipment. The absolute maintenance-free operation eliminates the time and cost for regular water topping-up and ensures maximum safety at work.

FAQs about the Sonnenschein GF 12 033 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 long periods. It is extremely cycle-resistant, meaning it can be deeply discharged and recharged repeatedly, as is the case with daily use in, e.g., electric wheelchairs. This distinguishes it from a starter battery.

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

The crucial advantage is complete maintenance freedom. For mobile devices, the time-consuming and error-prone checking and refilling of water is eliminated. Additionally, the batteries are leak-proof, even when inclined or with strong vibrations, significantly increasing 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 defines the discharge current. C5 (discharge over 5 hours) is the standard for traction applications as higher currents are drawn. C20 (discharge over 20 hours) is a common comparative value resulting in a higher nominal capacity.

How should this lead battery be disposed of?

Lead batteries contain environmentally harmful substances and must not be disposed of with household rubbish. You can return your old battery free of charge at any retailer selling new batteries, or at municipal collection points, to ensure proper recycling.
