What the MK Powered 8G4D is for

The MK Powered 8G4D 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 57.83 kg and EAPT terminals.

Will it fit your current battery tray?

In terms of format, the MK Powered 8G4D measures 527 × 214 × 250 mm (length × width × height) and weighs 57.83 kg. It uses EAPT terminals, the system that anchors and connects it in the vehicle. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters.

MK Powered: the maker behind the 8G4D

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. All the MK Powered batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

The MK Powered 8G4D: Mk GEL range and GEL technology

Within the MK Powered catalogue, the Mk GEL series groups the references designed for this use. The 8G4D is the 183 Ah model of that family, with the same performance as its siblings in other sizes.

GEL technology fixes the acid in a solid gel. That removes maintenance and leaks and gives very long cycle life, in exchange for slightly slower recharging and lower peak current than an AGM.

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. GEL batteries need lower charging voltages: always use a charger with a GEL mode so as not to damage the electrolyte.

Manufacturer's warranty

The MK Powered 8G4D 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.
