What the MK Powered ES9-12 is for

The MK Powered ES9-12 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 2.69 kg and F2 terminals.

Size, terminals and hold-down of the MK Powered ES9-12

In terms of format, the MK Powered ES9-12 measures 150 × 65 × 102 mm (length × width × height) and weighs 2.69 kg. It uses F2 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 ES9-12

MK Battery (MK Powered) is the US specialist in AGM and GEL batteries for mobility: power wheelchairs, scooters and medical equipment rely on its batteries for safety and cycle life. We guarantee that every MK Powered arrives new, charged and with the manufacturer's full warranty.

The MK Powered ES9-12: Mk AGM range and AGM technology

The Mk AGM is the MK Powered range the ES9-12 belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle.

AGM (Absorbent Glass Mat) technology seals the electrolyte in glass microfibre. The result is a maintenance-free battery that is highly vibration-resistant and able to withstand deep discharges that would ruin a classic lead-acid battery.

How to make it last longer

Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. Use the original charger or one compatible with the battery technology (AGM/GEL) and always replace both batteries in the set together.

Official warranty

The MK Powered ES9-12 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.
