It measures 228 Γ— 138 Γ— 210 mm, the format sought by anyone replacing a 48.4 Ah battery in power wheelchairs and mobility scooters. - Designed to be discharged and recharged daily without losing capacity. - AGM technology: absorbed electrolyte, no spills, can be mounted at an angle. - Standard replacement format for wheelchairs and scooters. - Thousands of useful cycles over its lifetime. ### What the MK Powered M22NF-HC is for The MK Powered M22NF-HC is designed for power wheelchairs, mobility scooters and light electric vehicles. Wheelchairs and scooters normally use two identical batteries in series: replace them together. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 18.14 kg. ### The MK Powered M22NF-HC: Mk AGM range and AGM technology Within the MK Powered catalogue, the **Mk AGM** series groups the references designed for this use. The M22NF-HC is the 48.4 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. ### Will it fit your current battery tray? The MK Powered M22NF-HC is made in the 228 Γ— 138 Γ— 210 mm format and weighs 18.14 kg. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### MK Powered: the maker behind the M22NF-HC 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. ### Usage and maintenance tips Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity. ### Manufacturer's warranty The MK Powered M22NF-HC 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. ### Delivery times and returns Same-day dispatch from our warehouse for in-stock orders placed **before [[ks:cutoff]]**: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for **[[ks:return_days]] days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email. ## Frequently asked questions ### Is the M22NF-HC model AGM? What does this technology offer? Yes. The M22NF-HC 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-HC 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 this page. 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 (βˆ’) 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 β€” match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (βˆ’). 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-HC battery last? Expected lifespan of the MK Powered M22NF-HC 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-HC battery? Dimensions (length Γ— width Γ— height) are 228Γ—139Γ—210 mm β€” also written as 228x139x210 mm β€” 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-HC 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 β€” 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. ## Reviews - **Average rating**: 4.7 / 5 (43 reviews) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team β€” over 25 years of experience validating automotive batteries. β†’ https://baterias.com/gb/technical-team --- *baterias.com β€” Automotive batteries Β· 2026-09-30*
