What the MK Powered 8G27 is for

The MK Powered 8G27 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 28.12 kg and DT terminals.

Technology inside the MK Powered 8G27

MK Powered builds the 8G27 to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position.

A GEL battery is the choice when cycle resistance and safety matter most: no gases, no liquid and thousands of partial discharges in its lifetime.

Dimensions, polarity and mounting

It has external dimensions of 326 × 167 × 241 mm and weighs 28.12 kg. It uses DT 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.
