What the MK Powered M40-12 SLD G is for

The MK Powered M40-12 SLD G is the usual replacement in power wheelchairs, mobility scooters and light electric vehicles. Recharge after each use and avoid leaving it discharged for days. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 14.29 kg and C (INSERT) terminals.

Dimensions, polarity and mounting

The MK Powered M40-12 SLD G is made in the 197 × 168 × 174 mm format and weighs 14.29 kg. It uses C (INSERT) terminals, the system that anchors and connects it in the vehicle. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.

Why choose MK Powered batteries

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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

The MK Powered M40-12 SLD G: Mk GEL range and GEL technology

The M40-12 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.

Care and maintenance

Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity. GEL batteries need lower charging voltages: always use a charger with a GEL mode so as not to damage the electrolyte.

Manufacturer's warranty

The MK Powered M40-12 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.
