>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.  >Applications 1.Solar and wind energy storage system2.EPS and UPS battery backup3.Signal system , emergency lighting system , security system4.Telecommunication Equipment5.Power source for portable devices or tools>Main Features1.Using oxygen recombination technology: maintenance-free2.PbCaSn alloy for plate grids: less gassing, less self-discharging3.High quality AGM separator: extend cycle life and prevent micro short circuit4.ABS material: increase the strength of battery container.
