Leoch battery performance characteristics:
◆ Silicon gel made of fumed silica and various additives has a three-dimensional porous network structure, which can adsorb sulfuric acid in the gel. At the same time, the capillary cracks in the gel are established for the oxygen precipitated from the positive electrode to reach the negative electrode. A channel is formed to realize the establishment of sealing reaction efficiency, so that the battery is completely sealed, there is no overflow of electrolyte and precipitation of acid mist, and no pollution to the environment and equipment.
 
◆ The electrolyte of the gel battery is in a gel state, without flow or leakage, and can be placed vertically or horizontally.
 
◆ Grid structure: The design of the middle and bottom corners of the tabs is dislocated. The bottom of the 2V series positive plate is covered with a plastic protective film, which can improve the reliability of the battery in operation. The alloy is made of lead-calcium-tin aluminum alloy, and the negative plate has a high hydrogen evolution potential. . The positive plate alloy is a high-tin and low-calcium alloy. Its structure is fine and dense, and its corrosion resistance is good. The battery has the characteristics of long service life.
 
◆ The separator adopts imported corrugated PVC separator for colloidal battery, which has large porosity and low resistance.
 
◆ The battery compartment and cover are made of ABS material and sealed with epoxy resin to ensure no leakage.
 
◆ The pole is made of pure lead material, which has good corrosion resistance. The pole and the battery cover use a pressure ring structure, that is, the pressure ring and the sealing rubber ring to achieve mechanical sealing of the battery pole, and then use resin sealing agent to bond to ensure its reliable sealing. sex.
 
◆ All series of 2V and 12V batteries are equipped with a gas filter and explosion-proof disc device. The outside of the battery will not be detonated when encountering an open flame, and the evolved gas will be filtered to make it non-polluting to the environment.
 
◆ Gel battery electrolyte is gel electrolyte, without acid stratification phenomenon, so that each part of the plate reacts evenly, and enhances the reliability of large battery capacity and service life.
