Its 97 × 24 × 56 mm make it the exact replacement for the 1.2 Ah battery fitted as standard to many power wheelchairs and mobility scooters. - Approved for air and sea transport (VRLA). - No maintenance, no water top-ups. - Sealed AGM/GEL: safe indoors and in transport. - AGM: faster recharging and better cycle resistance than a conventional battery. ### Dimensions, polarity and mounting It has external dimensions of 97 × 24 × 56 mm and weighs 0.29 kg. It uses F1 terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### What the MK Powered ES1.2-6 is for The MK Powered ES1.2-6 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 0.29 kg and F1 terminals. ### The MK Powered ES1.2-6: Mk AGM range and AGM technology The ES1.2-6 is part of the MK Powered **Mk AGM** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family. 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. ### Why choose MK Powered batteries 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. ### Manufacturer's warranty The MK Powered ES1.2-6 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 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. ### Shipping, delivery and returns Orders placed **before [[ks:cutoff]]** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have **[[ks:return_days]] days** to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships. ## Frequently asked questions ### Is the MK Powered ES1.2-6 an AGM battery and what are the benefits of AGM? Yes. The ES1.2-6 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 ES1.2-6 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 our blog. 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. ### How long does the MK Powered ES1.2-6 battery last? Expected lifespan of the MK Powered ES1.2-6 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 ES1.2-6 model? Dimensions (length × width × height) are 97×25×57 mm — also written as 97x25x57 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 interchangeable batteries are there for this one? 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. ## 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 · 2026-10-20*
