What Is Reducing The Service Life Of Lead-Acid Batteries
The lead-acid battery generates a lot of heat during charging, which causes the temperature of the battery to rise sharply. The charger has a big impact. With the increase in the number of times the battery is used, due to the consumption of electrolytes well as the reduction of the activity of the chemical substances in the internal resistance of the battery, the internal resistance of the battery will occasionally vary. As the temperature increases, the worse the quality of the battery, the faster it grows.
The impedance of the internal resistance of the battery will increase due to the increase of the discharge amount, especially when the discharge is terminated, if it continues to discharge, the lead sulfate will form a stable white crystal, even if it is charged, the active material of the plate will not be able to return to its original state, which will shorten the service life of the battery.
Battery cycle life refers to the number of repeated discharges a battery can experience. battery life and capacity are inversely proportional, and the cycle life is also closely related to the charging and discharging conditions. Generally, the charging current the larger the value, and the shorter the cycle life. Life is an indicator that indicates the speed at which the battery capacity decays. With the deepening of use, the attenuation of battery capacity is inevitable. When the battery capacity decays to a certain value, it can be judged that the life is over.
