The 12 V, 18 Ah MK Powered M17-12 SLD M from the Mk AGM range with AGM technology is the standard replacement for power wheelchairs, mobility scooters and light electric vehicles. Measuring 181 × 75 × 166 mm, it is the direct replacement for power wheelchairs and mobility scooters fitted from the factory with a 18 Ah battery of this format.

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

What the MK Powered M17-12 SLD M is for

The MK Powered M17-12 SLD M 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 5.85 kg.

Dimensions, polarity and mounting

It has external dimensions of 181 × 75 × 166 mm and weighs 5.85 kg. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a 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. We guarantee that every MK Powered arrives new, charged and with the manufacturer's full warranty.

The MK Powered M17-12 SLD M: Mk AGM range and AGM technology

The Mk AGM is the MK Powered range the M17-12 SLD M 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.

Care and maintenance

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.

Warranty and coverage

The MK Powered M17-12 SLD M 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.
