U1 Replacement Batteries

MK-U1, GEL Battery, 31AH, 1 Pair
Model: MU-1 SLD G
Rated non-spillable by ICAO, IATA and DOT

The U1 Battery size is the most popular battery used in Powered Mobility devices and is generally used in pairs.

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.

Sold in Pairs only.
  • Last longer than comparable wet lead/acid and marine batteries
  • approved for airline and public transportation
  • Do not need to be fully discharged before recharging
  • Sold in Pairs
  • 13 month warranty
