What the MK Powered 8G22NF is for
The MK Powered 8G22NF is the usual replacement in power wheelchairs, mobility scooters and light electric vehicles. Recharge after each use and avoid leaving it discharged for days. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 17.01 kg.
Will it fit your current battery tray?
The MK Powered 8G22NF is made in the 228 × 138 × 235 mm format and weighs 17.01 kg. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.
The MK Powered 8G22NF: Mk GEL range and GEL technology
Within the MK Powered catalogue, the Mk GEL series groups the references designed for this use. The 8G22NF is the 51 Ah model of that family, with the same performance as its siblings in other sizes.
In a GEL battery the electrolyte is gelled with silica: it is fully sealed, cannot spill and tolerates deep discharge very well. It is the preferred technology in electric mobility, marine service and heavy-cycling applications.
What MK Powered does differently
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. We guarantee that every MK Powered arrives new, charged and with the manufacturer's full warranty.
Official warranty
The MK Powered 8G22NF 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.
How to make it last longer
Use the original charger or one compatible with the battery technology (AGM/GEL) and always replace both batteries in the set together. GEL batteries need lower charging voltages: always use a charger with a GEL mode so as not to damage the electrolyte.

Frequently asked questions
Is the MK Powered 8G22NF a GEL battery? What is GEL used for?
Yes, this model is a GEL battery: sealed lead-acid where the electrolyte is in gel form. It tolerates deep discharges very well and is ideal for cyclic use (solar, motorhomes, electric wheelchairs, motorcycles). Requires a GEL-specific smart charger — max charge voltage ~14.1 V (vs 14.4-14.7 V for AGM). Lifespan 6-10 years.
What are the dimensions of the MK Powered 8G22NF battery?
Dimensions (length × width × height) are 228×139×235 mm — also written as 228x139x235 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.
MK Powered 8G22NF or MK Powered M22NF SLD G: which one to choose?
It has the same dimensions, voltage and technology as the 8G22NF, although it is not a manufacturer-approved equivalent. Compared with the 8G22NF it has 210 A of cold cranking more. It costs €197.80 more. Check the positive terminal side and the original capacity before ordering; otherwise it is a straight swap.
