It measures 150 × 65 × 102 mm, the format sought by anyone replacing a 7 Ah battery in power wheelchairs and mobility scooters. - Standard replacement format for wheelchairs and scooters. - Thousands of useful cycles over its lifetime. - Designed to be discharged and recharged daily without losing capacity. - AGM technology: absorbed electrolyte, no spills, can be mounted at an angle. ### What the MK Powered ES7-12SA is for The MK Powered ES7-12SA is the usual replacement in power wheelchairs, mobility scooters and light electric vehicles. Recharge after each use and avoid leaving it discharged for days. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 2.20 kg and F1 / F2 terminals. ### The MK Powered ES7-12SA: Mk AGM range and AGM technology The **Mk AGM** is the MK Powered range the ES7-12SA 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. ### Will it fit your current battery tray? The MK Powered ES7-12SA is made in the 150 × 65 × 102 mm format and weighs 2.20 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. ### 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. We guarantee that every MK Powered arrives new, charged and with the manufacturer's full warranty. ### Care and maintenance 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. ### Official warranty The MK Powered ES7-12SA 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. ### When you get it and how to return it Same-day dispatch from our warehouse for in-stock orders placed **before [[ks:cutoff]]**: 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 **[[ks:return_days]] days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email. ## Frequently asked questions ### Is the ES7-12SA model AGM? What does this technology offer? Yes. The ES7-12SA from MK Powered uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for devices with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions. ### How do I fit the ES7-12SA model in my device? In most devices it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on this page. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On devices with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile. ### What is the service life of the ES7-12SA model? Expected lifespan of the MK Powered ES7-12SA is 5 to 8 years in mild-climate device use with Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured. ### What are the measurements of the ES7-12SA model? Dimensions (length × width × height) are 151×65×102 mm — also written as 151x65x102 mm — following the European DIN standard. Always measure the space in your device before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals. ### Which batteries are equivalent to the MK Powered ES7-12SA? Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop devices. See the "Equivalents" section to view recommended options at the same performance level. ## Equivalent batteries - [KRONOBAT 12V7Ah](https://baterias.com/gb/battery-12v-7ah-agm) - [KRONOBAT ES7-12](https://baterias.com/gb/best-price-battery-12v-7ah-agm-es7-12) ## Reviews - **Average rating**: 4.77 / 5 (28 reviews) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — over 25 years of experience validating automotive batteries. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-09-28*
