MK Genuine Gel batteries have provided years of proven performance and significantly longer life - averaging 1 to 2 years or longer when properly maintained. That's why they have been the number one choice for years of the leading wheelchair manufacturers. When it comes to performance and quality, the MK Gel is the standard.

For lighter duty mobility use, MK Battery offers a line of AGM (absorbed glass mat) batteries.  Although AGM batteries will not match the cycle-life performance of our Genuine Gel batteries, they do offer a lower initial cost and will supply sufficient functionality to meet the less critical needs of certain lighter duty mobility applications.  For heavy daily use and traditional rehab applications, continued utilization of our heavy duty Gel batteries is highly recommended.
