What is GEL battery? 


Besides the characteristics of VRLA, 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 .

What is VRLA battery? 


VRLA(Valve Regulated Lead Acid) battery is sealed lead-acid battery. It includes 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).

2V 1000Ah Gel Battery Features:


•  Long design life (25 °C)20 years for 2V 

Low self-discharge rate:no bigger than 3 % per month 

High sealed reaction efficiency : bigger than 98% 

Grid: patent primary and secondary grid structure design; 

Positive plate: Pasted flat type, high temperature and humidity formation technics: 

Separator: high porosity PE separator with glass fibre good cyclic characteristics and lower resistance: 

Battery container: High strength ABS(UL94-HB) and UL94-VO is optional; 

Post sealing: patent double layer post sealing 

Safety Valve: narrow operate pressure range and equipped with explosion-proof arrester and acid filter.

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.
