MK Battery M34 Sealed GEL Battery, Pair

MK Battery M34 Sealed GEL Battery, Pair

SEALED VRLA GENUINE GEL BATTERIES

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.

• 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.

Gel Battery Benefits

• 4 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.
• Last longer than comparable wet lead/acid and marine batteries.
• Are approved for airline and public transportation.
• Do not need to be fully discharged before recharging.
• Do not develop a "memory" that limits their recharging.
• Do not need to be recharged with lower amps than wet lead/acid batteries.
• Will not automatically discharge if put on concrete.

Dimensions:

• Weight: 42 lbs each
• Length: 10.2"
• Width: 6.65"
  
• Height: 7.05"

GEL vs. AGM Sealed Batteries

AGM (absorbed glass mat) is a special design glass mat designed to wick the battery electrolyte between the battery plates. AGM batteries contain only enough liquid to keep the mat wet with the electrolyte and if the battery is broken no free liquid is available to leak out.

Gel Cell batteries contain a silica type gel that the battery electrolyte is suspended in, this thick paste like material allows electrons to flow between plates but will not leak from the battery if the case is broken.

More often than not an AGM Batteries are mistakenly identified as a Gel Cell Batteries. Both batteries have similar traits; such as being non spillable, deep cycle, may be mounted in any position, low self discharge, safe for use in limited ventilation areas, and may be transported via Air or Ground safely without special handling.

AGM Batteries outsell Gel Cell by at least a 100 to 1. AGM is preferred when a high burst of amps may be required. In most cases recharge can be accomplished by using a good quality standard battery charger or engine alternator. The life expectancy; measured as cycle life or years remains excellent in most AGM batteries if the batteries are not discharged more than 60% between recharge.

Gel Cell Batteries are typically a bit more costly and do not offer the same power capacity as do the same physical size AGM battery. The Gel Cell excels in slow discharge rates and slightly higher ambient operating temperatures. One big issue with Gel Batteries that must be addressing is the CHARGE PROFILE. Gel Cell Batteries must be recharged correctly or the battery will suffer premature failure. The battery charger being uséd to recharge the battery(s) must be designed or adjustable for Gel Cell Batteries. If you are using an alternator to recharge a true Gel Cell a special regulator must be installed.
