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.

◆ Excessive electrolyte, the colloid is in sol state when injected, which can fill all the space in the battery. In the case of high temperature and overcharging, the battery is not easy to dry up, the battery has large heat capacity, good heat dissipation, and is not easy to cause thermal runaway.

◆ The gel electrolyte of colloidal battery has a beneficial effect on the crystallization process of the positive electrode and negative electrode active material, so that the battery has a good deep discharge cycle ability, and the anti-sulfation resistance of the negative electrode is enhanced, so that the recovery ability of the battery after over-discharge is greatly improved.

◆ The battery can be used in a wide temperature range (-30℃～50℃), and the self-discharge electrode is low.

Main performance of LEOCH battery:

●Using a unique multi-alloy formula, using imported chip equipment and self-developed grid molds, and through strict temperature control, the grid not only has good thickness and weight uniformity, long floating charge life, and low self-discharge.

●Imported automatic computer-controlled lead powder machine is adopted to ensure the degree of oxidation of lead powder, uniformity and stability of particles with strict automatic control procedures, and at the same time, it is more suitable for the characteristics of high current discharge of batteries.

●Lead paste is the core of battery technology. The unique lead paste formula better meets various performance requirements such as high-power deep-cycle discharge, and is suitable for float charging and other fields. At the same time, the fully automatic paste mixing system and temperature control ensure the characteristics and stability of the lead paste.

●The imported smear machine is transformed with self-developed technology, so that the plates are more uniform and more suitable for the requirements of UPS battery plates.

●Using high temperature and high humidity curing technology, temperature and humidity automatic control technology, and through the perfect wind direction and flow design, the OTP battery not only guarantees the effect of plate curing to the maximum extent, but also ensures the uniformity of the plate at each point. The life is significantly improved compared to conventional curing.

●Using the quantitative acid addition process, the acid addition accuracy reaches 0.1ml, which fully guarantees the uniformity between the cells and between the cells.

At the same time, the unique formulation of the electrolyte enhances the deep cycle capability of the battery. And because of the use of imported epoxy glue, end piece and 0-type map for assembly, the battery is more reliable.

●Multiple charge and discharge cycles that must be passed before leaving the factory make the OTP battery more uniform and reliable. At the same time, the internal resistance, open and closed circuit, and tightness detection further ensure the quality of the factory battery.
