Gel/Sealed Lead Acid Batteries
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 1000 cycles (50% DOD) as fully tested by independent laboratories.
Gelled/Suspended Electrolyte: No
liquid of any kind; battery is completely sealed. Safe in any position
(except upside down).
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 of an Advanced Sealed Gel or
AGM Battery
Battery technology has changed tremendously in just the past few years.
In fact, size-for-size, MK's advanced sealed Gel and AGM batteries
deliver more power and more consistent performance than other types and
brands of batteries used for mobility. MK's performance-proven sealed
Gel and AGM designs:
Can last longer than other batteries due to high
quality manufacturing standards.
Are A-67 DOT/FAA-IATA Standard approved for airline and
public transportation.
Do not need to be fully discharged before recharging.
Do not develop a "memory" that limits their recharging.
Will not automatically discharge if put on concrete.
