Mobility battery MK Powered ES9-4 Mk AGM 9Ah 4V

The MK Powered ES9-4 with AGM technology delivers 9 Ah at 4 V with the cycle life that power wheelchairs, mobility scooters and light electric vehicles demand. Measuring 101 × 43 × 102 mm, it is the direct replacement for power wheelchairs and mobility scooters fitted from the factory with a 9 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 ES9-4 is for

With 9 Ah, the MK Powered ES9-4 offers the daily range that power wheelchairs, mobility scooters and light electric vehicles need, with a sealed construction that is safe indoors. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 1.18 kg.

Will it fit your current battery tray?

In terms of format, the MK Powered ES9-4 measures 101 × 43 × 102 mm (length × width × height) and weighs 1.18 kg. 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.

The MK Powered ES9-4: Mk AGM range and AGM technology

Within the MK Powered catalogue, the Mk AGM series groups the references designed for this use. The ES9-4 is the 9 Ah model of that family, with the same performance as its siblings in other sizes.

AGM means the acid is held in a glass mat instead of floating free. That is why the battery can be installed in the cabin without gases, survives more cycles and recovers its charge quickly.

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.

Warranty and coverage

The MK Powered ES9-4 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.

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. Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity.

Delivery times and returns

Order before 6:00 pm with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have 14 days to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email.
