The MK Powered ES3-12R: Mk AGM range and AGM technology

The Mk AGM is the MK Powered range the ES3-12R 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 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.

MK Powered: the maker behind the ES3-12R

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.

Official warranty

The MK Powered ES3-12R 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

Use the original charger or one compatible with the battery technology (AGM/GEL) and always replace both batteries in the set together. Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity.
