The Mk Powered ES12-12SA in practice

What the MK Powered ES12-12SA is for
The MK Powered ES12-12SA 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 3.74 kg.
Will it fit your current battery tray?
In terms of format, the MK Powered ES12-12SA measures 150 × 98 × 98 mm (length × width × height) and weighs 3.74 kg. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.
MK Powered: the maker behind the ES12-12SA
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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.
The MK Powered ES12-12SA: Mk AGM range and AGM technology
Within the MK Powered catalogue, the Mk AGM series groups the references designed for this use. The ES12-12SA is the 12 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.
Usage and maintenance tips
Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity. Use the original charger or one compatible with the battery technology (AGM/GEL) and always replace both batteries in the set together.
Warranty and coverage
The MK Powered ES12-12SA 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.
Shipping, delivery and returns
Same-day dispatch from our warehouse for in-stock orders placed before 6:00 pm: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for 14 days if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.
