Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 1.84 kg and F1 / F2 terminals. ### The MK Powered ES12-6: Mk AGM range and AGM technology The **Mk AGM** is the MK Powered range the ES12-6 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 (Absorbent Glass Mat) technology seals the electrolyte in glass microfibre. The result is a maintenance-free battery that is highly vibration-resistant and able to withstand deep discharges that would ruin a classic lead-acid battery. ### Size, terminals and hold-down of the MK Powered ES12-6 In terms of format, the MK Powered ES12-6 measures 150 × 50 × 99 mm (length × width × height) and weighs 1.84 kg. It uses F1 / F2 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. ### MK Powered: the maker behind the ES12-6 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. ### How to make it last longer Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. ### Official warranty The MK Powered ES12-6 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. ### Delivery times 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.

AGM (Absorbent Glass Mat) technology, 12 Ah and 6 V: sealed lead-acid, with the electrolyte held in glass fibre. Compared with a conventional battery it withstands more charge/discharge cycles and handles heat better. ### What are the dimensions of the MK Powered ES12-6 battery? Length × width × height: 151x50x99 mm. Height is measured to the top of the terminals. Measure your device's battery tray first; if the battery exceeds it by even a millimetre, the hold-down clamp may not close. ### MK Powered ES12-6 or MK Powered ES12-6 T2: which one to choose? Same case and same technology as the ES12-6: an alternative by size, not an official equivalent. Compared with the ES12-6 it has the same Ah and cranking power. It costs the same. If the polarity matches and your equipment had a similar capacity, it works as a replacement; if in doubt, ask us with your model. ### MK Powered ES12-6 or MK Powered ES12-6FR HR: which one to choose? It has the same dimensions, voltage and technology as the ES12-6, although it is not a manufacturer-approved equivalent. Compared with the ES12-6 it has the same Ah and cranking power.
