>About VRLA battery (AGM & GEL)

What is VRLA battery?

VRLA(Valve Regulated Lead Acid) battery is sealed lead -acid battery. liclides GEL type and AGM type, both have the following characteristics:

*is sealed using special pressure valves and should never be opened.

*is completely maintenance-free,needn't topping in service life.

*all of its electrolyte are immobilized (absorbed in AGM or fixed in Gel structure).

*uses recombination reaction to prevent the escape of hydrogen and oxygen gases which normally lost in flooded lead- acid battery.

*is non-spillable, and therefore can be operated in virtually any position(except upside down). 

What is GEL battery?

Besides the characteristics of VRL A, GEL battery has :

*using thixotropic gelled electrolyte, it is in a solid state between the plates and separators.

*not like traditional  AGM electrolyte "starve" design, GEL battery has more 15~25%electrolyte volume than AGM type.

*different type of separator, such as PE, PVC etc .

Differences between GEL batteries and absorbed glass mat(AGM) batteries?

*Both are sealed recombinant batteries. Both are sealed valve-regulated lead-acid (VRLA). 

 AGM batteries and GEL batteries are both considered "acid-starved" and the electrolyte does not flow like  a normal liquid.

*The gel electrolyte has the consistency and appearance of petroleum jelly. Like gelled electrolyte batteries, 

 AGM batteries are also considered non-spillable - all of the liquid electrolyte is trapped in the sponge-like matted glass fiber separator material.

*Due to the physical properties of the gelled electrolyte, gel battery has higher internal resistance. Thus AGM batteries has excellent 

  performance for high current/power discharge and GEL excels in high/lower temperature stability and lower current/power discharge applications.

*AGM batteries has higher specific energy density than GEL batteries. But GEL batteries has longer service life.

What is the difference between VRLA batteries and traditional wet/flooded batteries? 

*Wet batteries do not have special pressurized sealing vents, as they do not work on the recombination principle(gases escaped inside the battery during charging).

*It contains liquid electrolyte that can spill/flow and cause corrosion if tipped or punctured. Therefore, they are not air transportable without special containers.

*It can only be installed "upright" and "acid protection" must be maintained at the same time.

*As the wet batteries will lose gases during charging ,it is need maintenance(topping) periodically. 

*As the electrolyte can flow , "stratification" will occur and need more overcharge to mix.
