Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family. 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. ### 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. ### Official warranty The MK Powered ES17-12 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. ### 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. ### When you get it and how to return it Orders placed **before 6:00 pm** with the battery in stock ship the same day.

Compared with a conventional battery it withstands more charge/discharge cycles and handles heat better. ### What size is this battery? Check the room available in your device, because a single millimetre too much can stop the clamp from closing. Its dimensions are 181×76×167 mm, also written 181x76x167 mm; the height already includes the terminals. ### MK Powered ES17-12 or MK Powered ES22-12: which one to choose?
