Mobility battery MK Powered ES20-12C Mk AGM 20Ah 12V

Designed for power wheelchairs, mobility scooters and light electric vehicles, the MK Powered ES20-12C from the Mk AGM range offers 20 Ah of deep-cycle capacity with AGM technology. Its 181 × 75 × 166 mm make it the exact replacement for the 20 Ah battery fitted as standard to many power wheelchairs and mobility scooters.

• Approved for air and sea transport (VRLA).
• No maintenance, no water top-ups.
• Sealed AGM/GEL: safe indoors and in transport.
• AGM: faster recharging and better cycle resistance than a conventional battery.

Will it fit your current battery tray?

In terms of format, the MK Powered ES20-12C measures 181 × 75 × 166 mm (length × width × height) and weighs 5.94 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.

What the MK Powered ES20-12C is for

The MK Powered ES20-12C 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 5.94 kg.

The MK Powered ES20-12C: Mk AGM range and AGM technology

The Mk AGM is the MK Powered range the ES20-12C 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.

In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery.

MK Powered: the maker behind the ES20-12C

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

Warranty and coverage

The MK Powered ES20-12C 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.

Care and maintenance

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.
