MK Powered: the maker behind the M22NF SLD A
MK batteries are the standard in the electric mobility sector: sealed, approved for air transport and with the consistency that wheelchair manufacturers demand as original equipment. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.
The MK Powered M22NF SLD A: Mk AGM range and AGM technology
Within the MK Powered catalogue, the Mk AGM series groups the references designed for this use. The M22NF SLD A is the 55 Ah model of that family, with the same performance as its siblings in other sizes.
AGM means the acid is held in a glass mat instead of floating free. That is why the battery can be installed in the cabin without gases, survives more cycles and recovers its charge quickly.
Usage and maintenance tips
Use the original charger or one compatible with the battery technology (AGM/GEL) and always replace both batteries in the set together. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators.
Manufacturer's warranty
The MK Powered M22NF SLD A comes with the manufacturer's official warranty against manufacturing defects. If it fails through a defect within the warranty period, we replace it at no cost to you.
Shipping, delivery and returns

Frequently asked questions
Is the M22NF SLD A model AGM? What does this technology offer?
Yes. The M22NF SLD A from MK Powered uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for devices with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions.
How do I fit the M22NF SLD A model in my device?
In most devices it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on our blog. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On devices with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.
How long does the MK Powered M22NF SLD A battery last?
Expected lifespan of the MK Powered M22NF SLD A is 5 to 8 years in mild-climate device use with Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured.
What are the dimensions of the MK Powered M22NF SLD A battery?
Dimensions (length × width × height) are 244×139×235 mm — also written as 244x139x235 mm — following the European DIN standard. Always measure the space in your device before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.
What are the equivalents of the M22NF SLD A model?
Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop devices. See the "Equivalents" section to view recommended options at the same performance level.
