Sealed VRLA Gel Batteries 
When you think quality Deep Cycle batteries, think of MK Battery. Our premium Gel products have been the number one choice for years by the leading wheelchair manufacturers. When it comes to performance and quality, the MK Gel is the standard.

 Deep Cycle: Premium sealed batteries capable of up to 1000 cycles (50% DOD) as fully tested by independent laboratories.
 Gelled/Suspended Electrolyte: No liquid of any kind; battery is completely sealed. Safe in any position (except upside down).   
 Maintenance Free: Water is never added; low liability 
 Travel & Ship Easily: MK batteries are F.A.A, IATA, and UPS approved. Others may not be. 
 Safety: Sealed batteries have a special re-sealing vent system that prevents excessive internal pressure; thus they cannot explode under normal conditions.

Benefits of an Advanced Sealed VRLA Gel or AGM Battery 
Battery technology has changed tremendously in just the past few years. In fact, size-for-size, MK's advanced Sealed VRLA Gel and AGM batteries deliver more power and more consistent performance than other types and brands of batteries used for mobility. MK's performance-proven Gel and AGM designs:

 Can last longer than other batteries due to high quality manufacturing standards. 
 Are A-67 DOT/FAA-IATA Standard approved for airline and public transportation. 
 Do not need to be fully discharged before recharging.
 Do not develop a "memory" that limits their recharging. 
 Will not automatically discharge if put on concrete.

You'll Cover More Ground with an MK Battery. Like a good set of radial tires for your car, MK Sealed VRLA Gel and AGM batteries, designed to enhance performance and safety, last longer and provide more cost efficient reliability. 

An MK Sealed VRLA Gel battery features an inherently safer, truly maintenance-free design. MK Gel batteries have provided years of proven performance and significantly longer life - averaging 1 to 2 years or longer when properly maintained.

MK Battery also offers a line of AGM (absorbed glass mat) batteries for lighter duty mobility use. Although AGM batteries will not match the cycle-life performance of our 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.
