Product Description

Generally Features:
1. GEL Technology
The success of DG batteries comes from the internationally superior Gel technology. It is ideal for standby or frequent cyclic discharge applications under extreme environments
2. Long Life Time
Specially designed for telecommunication use with 10+ years of design life in float service. By combining the newly developed paste formula with up-to-date AGM structures, this range features 12 years of design life. By using strong grids, high-purity lead, and patented Gel electrolyte, the DGseries offers excellent recovery after deep discharge under frequent cyclic discharge use and can deliver 400 cycles at 100% DOD.
3. Excellent Recovery from Deep Cycle
Unique technical processes are used in the grid alloy and electrolyte additive, in this case, the battery can be recharged after being over-discharged.

Battery Use and Maintenance:
1. Please use constant-voltage charge.2. In floating charge, the voltage is 2.23 to 2.27 per unit cell.
3. In cycle use, the voltage is 2.35 to 2.45 per unit cell, the max. Current is no more than 25%° C
4. Please do tighten the bolts to avoid sparkle and poor contact when the battery is in use.
5. Please do not use it near the heat source and open flame.
6. Please keep it at low temperature. Please change it while there is liquid leaking or damage.

Production Process

FGET is a Lead Acid Battery Manufacturer, and the following is FGET Lead Acid Battery Production Process

More Details Click here 

(1) Lead powder and cast alloy grid:The lead powder is the primary raw material for making battery plate active material. The qualified lead bars are cut into lead pellets filled in the ball mill, and through the rotating drum, the lead balls fall under the action of their gravity, collide with each other, and rub into powder. The grid is the skeleton of the plate, the carrier of current conduction, and the adhesion of active substances so that the current passing through the plate is evenly distributed.

 

(2) Mixing: The combined paste is a paste-like substance formed by mixing lead powder, water, sulfuric acid solution, and additives uniformly by mechanical stirring. A mixture of basic lead sulfate, oxide, and free lead is produced in a certain shape and proportion. The quality of the paste directly affects the capacity and life of the battery. Apply the mixed lead paste on the alloy grid, compact, and pour acid. After the dry surface, make the grid and the lead paste tightly combined, and the surface is free of defects and cracks. After this step, the wet unformed plate is formed.

 

(3) Plate formation:The curing principle is to make the wet raw plate after drying on the surface, under the conditions of controlling relative temperature, humidity, and time, to make the wet raw plate lose moisture. The unformed plate is fully oxidized and corroded to form a plastic active substance, condensed into a solid substance with uniform pores.

 

(4) Polish&cutting:Divide the large scale into plates of the shape and size required by the process by cutting

 

(5) Plate wrapping:This is a process of energy distribution, which is a process of combining positive plates, negative plates, and separators into a plate separator body according to the specified number of leaves and the order of the plate direction.

 

(6) Equipment: Connect the positive and negative plate of the grid plate by casting and welding, respectively. After launching and welding, the semi-finished battery with a protective mesh is placed on the top of each single-grid plate group, and a certain amount of epoxy is placed upside down. In the middle cover groove of the resin, adhere the battery bottom case to the central cover, weld the terminals, and apply colored glue to distinguish the positive and negative plate.

 

(7) Add acid: Add a rated amount of electrolyte to each battery cell by vacuum negative pressure.

 

(8) Battery inner formation is the process of turning unformed plates into mature plates. The acid solution reacts with the plates to identify the quality of the battery. Connect the specified number of batteries in series, charge, and discharge according to the process, activate the battery, and make the positive and negative active materials form a certain amount of lead dioxide and spongy lead.

 

(9) Packaging: Print the trademark of the charged battery and pack it in a box.
