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. We guarantee that every MK Powered arrives new, charged and with the manufacturer's full warranty. ### Official warranty The MK Powered ES5-12SA 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. ### 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. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. ### 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.

You will receive tracking by email. ## Frequently asked questions ### Is the MK Powered ES5-12SA an AGM battery and what are the benefits of AGM? Yes, it is AGM. In an AGM battery such as the ES5-12SA, the electrolyte is not free but absorbed in a glass-fibre mat inside a sealed lead-acid battery. It tolerates heat better and handles more cycles than a conventional battery. ### What are the dimensions of the MK Powered ES5-12SA battery? Its dimensions are 90×70×107 mm, also written 90x70x107 mm; the height already includes the terminals. Check the room available in your device, because a single millimetre too much can stop the clamp from closing. ### MK Powered ES5-12SA or MK Powered ES5-12: which one to choose?
