Products Description

Long life and high quality Gel Batteries

KG series refer to Nano-gelled Valve Regulated Lead Acid batteries. With special Nano-gelled technology, the insider electrolyte is fixed. The efficient design ensures stronger power and higher capacity density. Leakage-proof design with high capacity density means no layer of liquid and a low self-discharge. Battery's ability in deep discharge is greatly promoted through this way.Gel batteries are reliable and of good performance in both Cycle use and floating charge use.This series Batteries have various types based on the capacity, to meet the diversified need of customers.These batteries also with wide application in emergency lighting, telecommunication, security system and medical equipment as the back up power, and in electronic wheel chair, solar power system, boat and navigation euipment for cycle use.


Gel battery features:

 1.Working temperature: -40°C to 60°C.

 2.Float charging life: 10 years(under a normal condition of 20°C)
 3.Plenty electrolyte, larger heat capacity, good ability to dissipate heat.
 4.Special sealed structure,and no leakage because of the gel electrolyte, so safe and reliable.
 5.Special design of lead and calcium alloy lessens the corrosion of grid,making the using life longer.

Product Parameters:

KG 12-40


Battery construction:

1.Positive plate and negative plate:
Special design of lead and calcium alloy bringd goos resistance to corrosion and a longer service life.

Use imported nano-gelled electrolyte with fumed silica, and density is well distributed. No layer of insider lead acid will happen.

3.ABS plastic battery box:
High-strength ABS plastic box with nice shape and firmness, broke and deformation won't happen.

High quality super-thin absorbed glass mat is used, so the rate of gas recombination is more than 99 percent.

5.Terminal post:
Copper terminal post brings a better currrent-carrying ability and good resistance to corrosion.
