When seeking the highest quality Deep Cycle batteries, look to MK Battery. 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.

Please note that most mobility products are 24 Volt systems and therefore require 2 batteries.  Batteries should always be replaced in pairs.

  • Genuine Gel Technology: In compliance with international standards that define Gel batteries, the electrolyte is completely immobilized in a highly viscous gelling agent in order to prevent spillage. 
  • Increased Durability:  MK Genuine Gel batteries can deliver 2 to 3 times the cycle life of AGM batteries in Complex Rehab Technology (CRT) and other high-demand, deep-cycle applications.
  • Gelled/Suspended Electrolyte: No liquid of any kind; battery is completely sealed. Safe in any position (except upside down).
  • Deep Cycle: Premium Sealed VRLA batteries capable of over 1000 cycles (50% DOD) as fully tested by independent laboratories.
  • Travel & Ship Easily: FAA, IATA, DOT and UPS approved. Others may not be.
  • Safety: MK Sealed VRLA batteries have a special re-sealing vent system that prevents excessive internal pressure, thus minimizing risk of explosion under normal conditions.
  • Sealed Construction for Maintenance-Free Use: Eliminates periodic watering, corrosive acid fumes and spills.
  • Electrolyte Will Not Stratify: No equalization charging required.  Allows faster recharge.
  • 10% More Electrolyte: Longer life and minimal dry out over extended use.
  • Less Than 2% Per Month Self-Discharge: Little deterioration during transport and storage.
  • Individual Plate Formation (IPF®) Technology: Optimizes power capacity, cell consistency, and long-term reliability.
  • Quality Construction: Ensures consistent and reliable performance for long-term dependability.
  • Flame Arresting, Low Pressure, Self-Sealing Valves: All 100% factory tested.
  • Forged Terminals and Bushings: Assures no leakage.
  • Over 250 Quality Control Checks: Certified to ISO 9001.
  • UL Recognized Component.
  • Made in USA With U.S. and Imported Materials.
