Maximum performance for demanding cyclic applications

The MK M22NFSLDG was specifically designed for tough, cyclic daily use. Its main area of application is demanding rehabilitation technology, where it supplies power wheelchairs and electric vehicles with long-lasting and reliable energy. As a storage battery in stand-alone solar systems and independent power supplies, it proves its reliability. In addition, it is an excellent energy source for industrial cleaning machines, lifting platforms and marine applications.

Advanced and proven gel technology

Unlike conventional wet or AGM batteries, a gel battery has the electrolyte thickened in a silica gel. This completely prevents leakage and eliminates the need to top up with water. The gel technology offers excellent resistance to vibrations, very low self-discharge and above all outstanding tolerance to deep discharges. This makes them the safest and most durable choice for intensive supply applications.

Longevity and economy in focus

The MK gel battery is an investment in longevity and operational reliability. Its ability to withstand hundreds of deep charge and discharge cycles reduces the need for premature replacement and therefore significantly lowers the total operating costs of your equipment. High-quality workmanship and the use of high-purity materials ensure constant power output and reliable performance over the entire long service life.
 

Characteristics

FAQs about the MK Gel Battery M22NFSLDG

What does "Deep Cycle" mean?

"Deep Cycle" means that the battery is designed to regularly discharge a large part of its stored energy (deep discharge) and then be fully recharged without rapidly losing capacity. This is crucial for supply applications, as opposed to starter batteries, which only deliver high currents briefly.

What is the main difference between gel and AGM batteries?

Both are maintenance-free non-woven batteries. In gel batteries, however, the electrolyte is thickened to a gel consistency, whereas in AGM batteries it is bound as a liquid in a glass fibre mat. Gel batteries generally offer even higher cycle stability and better tolerance to deep discharges, making them the premium solution for the most demanding supply applications.

Which charger do I need for this gel battery?

You need a modern, microprocessor-controlled charger that has a special charging characteristic for gel batteries. The charging voltage for gel batteries is usually somewhat lower than for AGM or wet batteries. Using the wrong charger can significantly shorten the service life of the battery.

Can I connect two of these batteries in series to get 24V?

Yes, this is a very common application, especially in electric vehicles, wheelchairs or for 24V solar systems. To ensure optimum performance and service life, always use two identical batteries (same model, same capacity) which ideally come from the same production batch and have the same state of charge.

How must this lead battery be disposed of?

Lead batteries contain environmentally harmful substances and must not be disposed of in household waste. You can return your old battery to any retailer selling new batteries or to local recycling centres free of charge to ensure proper recycling.
