Changes of lead-acid battery capacity at different temperatures

Changes of lead-acid battery capacity at different temperaturesThe capacity of the lead-acid battery is in the temperature of different environments, and there is a difference in temperature, and there are differences in battery discharge and charging. In the south and northern, the capacity of lead-acid batteries can only be released. 65%, charging time also needs to be extended, and the rated capacity of the battery is usually specified at 25 ¡ã C ambient temperatures and at the specified discharge rate. The best operating temperature of the battery is 25 ¡ã C, when the battery discharge operating temperature is not 25 ¡ã C, due to the effect of electrochemical, the actual capacity should be converted into a 25 ¡ã C reference temperature in the formula (1).





Valve-type sealed lead-acid battery is widely used in submarines, tanks, computers, communications, solar batteries, etc. in some special use areas, or in use areas. For example, low temperature capacity requirements, -40 ¡ã C low temperature 5 hours (termination voltage 10.2V) capacity is not less than 30% of normal temperature capacity. The normal lead paste formulation is used, and the low temperature capacity of -40 ¡ã C will drop to about 30% of normal temperature, so that the product is very low. The temperature is reduced, and the viscosity of the electrolyte is increased, the permeability is weakened; the internal resistance of the battery increases, the internal voltage drop is increased. Under these factors, the battery discharge capacity is reduced. In addition, in low temperature environmental conditions, the general valve-controlled lead-acid battery negative electrode active material decreases with temperature, and the charging acceptance capacity is rapidly lowered, and the discharge performance of the battery will further reduce the battery's perfor  Recommend: LiFePO4 Battery Manufacturer Energy storage battery Manufacturer Integrated machine energy storage battery series Manufacturer Lead lithium battery Manufacturer Outdoor Backup Battery Manufacturer Portable outdoor power supply Manufacturer Power battery Manufacturer Powerwall LiFePO4 Battery Manufacturer Battery rack Manufacturers Telecom LiFePO4 Battery Manufacturer Wall mounted battery storage Manufacturer China Lifepo4 Battery
