It uses F1 terminals, the system that anchors and connects it in the vehicle. 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 ES3-6 is for The MK Powered ES3-6 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 0.67 kg and F1 terminals. ### The MK Powered ES3-6: Mk AGM range and AGM technology Within the MK Powered catalogue, the **Mk AGM** series groups the references designed for this use. The ES3-6 is the 3 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 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. All the MK Powered batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Manufacturer's warranty The MK Powered ES3-6 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. ### Care and maintenance Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. Use the original charger or one compatible with the battery technology (AGM/GEL) and always replace both batteries in the set together. ### When you get it and how to return it 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. ## Frequently asked questions ### Is the ES3-6 model AGM? What does this technology offer? Yes: the ES3-6 from MK Powered uses AGM (Absorbent Glass Mat) technology, a sealed lead-acid battery whose electrolyte soaks a glass-fibre mat. It tolerates heat better and handles more cycles than a conventional battery. ### What size is this battery? It measures 134×34×65 mm in length × width × height, with the terminals included in the height. Measure the battery tray before ordering: a one-millimetre difference is enough for the hold-down clamp not to close. ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2012. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-11-12*
