Description

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.
