It has external dimensions of 328 × 171 × 247 mm and weighs 31.07 kg. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### What the MK Powered M31 SLD G is for The MK Powered M31 SLD G 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 31.07 kg. ### The MK Powered M31 SLD G: Mk GEL range and GEL technology The M31 SLD G is part of the MK Powered **Mk GEL** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family. GEL technology fixes the acid in a solid gel. That removes maintenance and leaks and gives very long cycle life, in exchange for slightly slower recharging and lower peak current than an AGM. ### 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. ### Manufacturer's warranty The MK Powered M31 SLD G 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 GEL batteries need lower charging voltages: always use a charger with a GEL mode so as not to damage the electrolyte. Use the original charger or one compatible with the battery technology (AGM/GEL) and always replace both batteries in the set together. ### When you get it and how to return it Orders placed **before 6:00 pm** with the battery in stock ship the same day.

We email you the tracking number as soon as the parcel ships. ## Frequently asked questions ### Is the M31 SLD G model a gel battery? Where is it used? Yes. The MK Powered M31 SLD G is GEL: sealed lead-acid in which the electrolyte is a gel. Its maximum charge voltage is lower than an AGM's, so a GEL-specific smart charger is needed. Deep discharges are its strong point, so it suits cyclic use: solar, motorhomes, electric wheelchairs or motorcycles. ### What size is this battery? Measure the battery tray before ordering: a one-millimetre difference is enough for the hold-down clamp not to close. It measures 328×171×248 mm in length × width × height, with the terminals included in the height. ### MK Powered M31 SLD G or MK Powered E31 SLD G: which one to choose? It has the same dimensions, voltage and technology as the M31 SLD G, although it is not a manufacturer-approved equivalent. Compared with the M31 SLD G it has 450 A of cold cranking more. It costs €361.40 more. Check the positive terminal side and the original capacity before ordering; otherwise it is a straight swap. ## Compatible vehicles This battery fits 2 vehicles.
