Maximum performance for demanding traction applications

The Sonnenschein GF 12 090 V is the specialist for mobile, electrically powered machines and vehicles. Its main areas of application are industrial floor cleaning machines, electric lifting and working platforms, driverless transport systems (AGVs), electric pallet trucks and golf carts. Wherever machines have to work reliably and maintenance-free on a daily basis, this battery provides the necessary energy.

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 maintenance-free, but also ensures excellent cycle stability and very low self-discharge. In contrast to conventional wet batteries, acid stratification is prevented, which significantly extends the service life in hard cycle operation.

Developed for longevity and economy

The GF-V series was developed to maximise efficiency and minimise downtime in professional applications. The long cycle life reduces the need for premature replacement and thus lowers the total cost of ownership (TCO) of your fleet. Completely maintenance-free, it eliminates the time and expense of regular water refilling and ensures maximum work safety.

FAQs about the Sonnenschein GF 12 090 V lead-gel battery

What does "traction battery" mean?

A traction battery (or traction battery) is specially designed to supply electric motors with energy over a longer period of time. It is extremely cycle-resistant, i.e. it can be deeply discharged and recharged regularly, which is the case in the daily use of cleaning machines, for example. This distinguishes it from a starter battery.

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

The decisive advantage is the absolute freedom from maintenance. For a fleet of cleaning machines or lifting platforms, the time-consuming and error-prone checking and topping up of water is no longer necessary. The batteries are also leak-proof and more resistant to vibrations, which increases operational safety 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-acid battery be disposed of?

Lead-acid batteries contain environmentally harmful substances and must not be disposed of with household waste. You can return your old battery to any retailer that sells new batteries or to municipal recycling centres free of charge to ensure that it is recycled properly.
