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

Designed for power wheelchairs, mobility scooters and light electric vehicles, the MK Powered ES20-12FR HR 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.

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

Dimensions, polarity and mounting

In terms of format, the MK Powered ES20-12FR HR 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 ES20-12FR HR is for

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

The ES20-12FR HR is part of the MK Powered Mk AGM range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.

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.

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

Official warranty

The MK Powered ES20-12FR HR 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.

Usage and maintenance tips

Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity.
