Gel Batteries

Advanced design / manufacturing, including IPF® technology†, combine to make MK Battery's Sealed Gel Batteries; the standard by which all other gel batteries are measured.

Gel batteries are classified as a valve regulated lead acid batteries (VRLA) which are maintenance free lead acid batteries. Gel batteries are pre-sealed; and water checking is not required on regular interval.

  • Gel batteries are maintenance free, there is no need to check the level of the electrolyte
  • Gel batteries are leak proof.
  • For Gel batteries additional safety gear not required
  • Easy operation in most temperatures - Gel batteries can operate in a variety of temperatures from very high to low.
  • Gel batteries don't leak or produce spills or corrosion
  • Gel does not flow out of the battery, even if they are cut open.
  • Gel batteries are not known to evaporate.
  • Gel batteries have a better resistance to extreme temperature changes and are more vibration resistant and shock resistant.

MK Gel Sealed.

The Mobility Industry Standard.

When you think quality Deep Cycle batteries, think of MK Battery. Our premium gel sealed battery 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 1100 cycles for atypical HME user.
  • Gelled/Suspended electrolyte - No liquid of any kind battery is completely sealed. Safe in any position.
  • 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

  • Sealed construction eliminated periodic watering, corrosive acid fumes and spills.
  • Electrolyte will not stratify, no equalization charging required. Allows faster recharge.
  • Increases durability and deep cycle ability for heavy demand applications.
  • Less than 2% per month stand loss means little deterioration during transport and storage.
  • Individual plate formation (IPF) technology optimizes power capacity, cell consistency, and long-term reliability.
  • Transports easily and safely by air.
  • Quality construction ensures reliable performance.

AGM Batteries

AGM (Absorbed Matt Glass) batteries, or dry cell batteries are the newest type of battery, that can be substituted for wet cell batteries. AGM batteries are sealed, lead-filled batteries designed to prevent leakage. These batteries charge approximately five times faster than other most of the batteries and have a high resistance to vibrations. AGM batteries are safe and more durable when being moved from place to place, but AGM batteries can be ruined during the charging process.
