MK Gel battery E31 SLD G 12V 108Ah

The MK E31 SLD G is an ultra-modern and absolutely maintenance-free deep-cycle gel battery that has been developed to meet the highest demands for cycle stability, safety and durability. With a nominal voltage of 12 V and a high capacity of 108 Ah (C100), this accumulator offers outstanding performance in demanding cyclic use. The advanced gel technology makes it the first choice for critical applications in rehabilitation technology, for solar systems and in all areas where maximum reliability and a long service life are required.

Highlights at a glance

• Superior gel technology: The electrolyte bound in gel ensures maximum cycle stability and a very long service life.
• Genuine deep-cycle performance: Developed for deep and regular discharge cycles without loss of capacity.
• Absolutely maintenance-free and leak-proof: Sealed construction allows installation in any position and indoors.
• Excellent discharge recovery: Recovers reliably even after deep discharges.
• Versatile in use: Ideal for electric vehicles, solar systems, cleaning machines and marine applications.

Maximum performance for demanding cyclic applications

The MK E31 SLD G was specifically developed for tough, cyclic everyday use. Its main area of application is in demanding rehabilitation technology, where it supplies electric vehicles and electric wheelchairs with long-lasting energy. It proves its reliability as a storage battery in off-grid solar systems and in self-sufficient power supplies. It is also the perfect energy source for industrial cleaning machines, lifting platforms and marine applications that require a robust and cycle-resistant battery.

Advanced and proven gel technology

In contrast to conventional wet or AGM batteries, the electrolyte in a gel battery is 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 it 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 safety. Its ability to withstand hundreds of deep charge and discharge cycles reduces the need for premature replacement and thus significantly lowers the overall operating costs of your equipment. The high-quality workmanship and the use of high-purity materials ensure constant power delivery and reliable operation throughout the entire, long service life.
 

Characteristics

FAQs about the MK Gel Battery E31 SLD G

What does "Deep Cycle" mean?

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

What is the main difference between gel and AGM batteries?

Both are maintenance-free non-woven batteries. However, in gel batteries the electrolyte is thickened into a gel, while in AGM batteries it is bound in a liquid form 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 accumulators is usually somewhat lower than for AGM or wet batteries. Using the wrong charger can significantly shorten the 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, you should always use two identical batteries (same model, same capacity), ideally from the same production batch and with the same state of charge.

How must this lead-acid 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 free of charge to any dealer who sells new batteries or to municipal recycling centres to ensure proper recycling.
