Product Description

>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 system

2.EPS and UPS battery backup

3.Signal system , emergency lighting system , security system

4.Telecommunication Equipment

5.Power source for portable devices or tools

>Main Features

1.Using oxygen recombination technology: maintenance-free
2.PbCaSn alloy for plate grids: less gassing, less self-discharging
3.High quality AGM separator: extend cycle life and prevent micro short circuit
4.ABS material: increase the strength of battery container. (Flame-retardant ABS is optional);
5.High purity raw material: ensure low self discharge rate
6.Silver-coated copper terminals (T1, T2 terminal), brass insert terminals and lead terminals improve the electric conductivity

Q6.What is your warranty time for VRLA battery ?
A6: It depends on battery capacity, depth of discharge, and battery usage. Please kindly contact us for accurate information based on detailed requirements.
 
Q7. Why battery has different capacity at different hour rate?
A7: The capacity of a battery, in Ahs, is a dynamic number that is dependent on the discharge current. For example, a battery that is discharged at 10A will give you more capacity than a battery that is discharged at 100A. With the 20-hr rate, the battery is able to deliver more Ahs than with the 2-hr rate because the 20-hr rate uses a lower discharge current than the 2-hr rate.
