Frequently asked questions
Is the MK Powered 8G31 a GEL battery? What is GEL used for?
Yes, this model is a GEL battery: sealed lead-acid with the electrolyte in gel form. 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 are the dimensions of the MK Powered 8G31 battery?
It measures 328×171×237 mm in length × width × height, with the terminals included in the height. Measure the battery tray before ordering: a one-millimetre difference is enough for the hold-down clamp not to close.
