MK-M17 Sealed GEL Battery

1 Pair

Replacement batteries for many Invacare Scooters and portable power wheelchairs. Sealed GEL Batteries.

Battery technology has changed tremendously in just the past few years. In fact, size-for-size, MK's advanced gel/sealed batteries deliver more power and more consistent performance than other types and brands of mobility batteries. Better still, and contrary to popular belief, MK's performance proven gel/sealed designs.

Although a wet/acid design is initially less expensive and can provided about 10% more running time per charge than a gel/sealed battery of equal size, a wet lead/acid battery has a much shorter service life, requires regular maintenance and poses a much higher safety risk because of potential battery acid contact and/or explosion.

An MK gel/sealed battery, instead provides an inherently safer, truly maintenance-free design. MK batteries provide a significantly longer life-averaging 1 to 2 years or longer when properly maintained - and are available in models approved by major airlines and other public transportation providers.

Batteries for my wheel chair.
I attempted to get the batteries from another source prior to contacting PHC. After a significant waiting period (almost two weeks, and many, many, many phone calls and hang ups, )I cancelled the order from them and found your web site. Within three days of contacting PHC, I had the batteries in hand. My wheel chair worked perfectly and your staff were a 100% helpful! Thank you. Elke Maxwel
