102450 lipo battery

　　How to repair 102450 lipo battery and what factors affect their lifespan?

　　Repair methods for failed 102450 lipo battery include pulse repair method, strong current repair method, water replenishment repair method, reconfiguration repair method, etc.; in addition, the factors that affect the life span are battery discharge depth, overcharge degree, temperature, and sulfuric acid concentration. Impact, etc., the relevant content will be introduced in detail below.

　　1. Repair method of lead-acid battery

　　1. Pulse repair method

　　A high-frequency positive and negative pulse generator is used to continuously generate high and low variable frequency pulses on the battery, destroying the conditions for the continued growth of large lead sulfate. This method overcomes the limitations of previous repair technologies and is rapid and takes about 8-12 hours. It has the advantages of high repair efficiency, low power consumption, and will not cause the battery to lose water, soften the positive plate, or change the original structure of the electrolyte.

　　2. Strong electricity repair method

　　The strong current repair method is a method of repairing the battery using long-lasting high voltage or large current during charging. It is mostly used when the pulse repair method is not effective.

　　3. Full charge and full discharge repair method

　　The full charge and full discharge repair method is to fully charge the battery and then completely discharge it to repair the battery.

　　4. Hydration and repair method

　　The "water loss" of the battery can be repaired by replenishing water. The purpose is to dilute the sulfuric acid with increased concentration to carry out the electrolysis reaction normally.

　　5. Reconfiguration and repair method

　　Electric vehicle batteries are generally a battery pack composed of several batteries connected in series. Battery damage can occur in many ways.

　　2. Factors affecting the life of 102450 lipo battery

　　1. Discharge depth

　　The depth of discharge refers to the point at which discharge stops during use. 100% depth refers to the discharge of all capacity. The life of 102450 lipo battery is greatly affected by the depth of discharge. The key design considerations are deep circulation use, shallow circulation use or float charging use. If a shallow cycle battery is used for deep cycle use, the lead-acid battery will fail quickly.

　　Because the positive active material lead dioxide itself is not firmly bonded to each other, lead sulfate is generated during discharge, and returns to lead dioxide during charging. The molar volume of lead sulfate is larger than that of lead oxide, so the volume of the active material expands during discharge. If one mole of lead oxide is converted into one mole of lead sulfate, the volume increases by 95%. Such repeated contraction and expansion will gradually relax the mutual bonds between lead dioxide particles and make them easy to fall off. If only 20% of one mole of lead dioxide active material is discharged, the degree of shrinkage and expansion will be greatly reduced, and the bonding force will be destroyed slowly. Therefore, the deeper the discharge depth, the shorter its cycle life.

　　2. Degree of overcharge

　　A large amount of gas precipitates during overcharging. At this time, the active material of the positive plate is impacted by the gas. This impact will promote the shedding of the active material. In addition, the positive plate alloy is also subject to severe anodic oxidation and corrosion, so the battery will be overcharged. The application period is shortened.

　　3. Effect of temperature

　　Lead-acid battery life increases as temperature increases. Between 10°C and 35°C, for every 1°C increase, approximately 5 to 6 cycles will be added. Between 35°C and 45°C, every 1°C increase can extend the life by more than 25 cycles; above 50°C, the lifespan will increase by more than 25 cycles. The negative electrode vulcanization capacity is lost and the service life is reduced.

　　Battery life increases with temperature within a certain temperature range because capacity increases with temperature. If the discharge capacity remains unchanged, the discharge depth will decrease and the solid life will be extended when the temperature increases.

　　Is the service life of a lead-acid battery the number of years or the number of uses? What is the difference between lead-carbon batteries, 102450 lipo battery and lead-carbon batteries?

　　4. Effect of sulfuric acid concentration

　　Although the increase in acid density is beneficial to the capacity of the positive plate, the self-discharge of the battery increases and the corrosion of the grid also accelerates, which also promotes the loosening and shedding of lead dioxide. As the acid density increases in the battery, the cycle life decreases.
