Why do lead-acid batteries have a short lifespan?


Many people think that the quality of lead-acid batteries is not as good as before, and the lifespan is not as good as before. Batteries that used to last for two to three years, or even longer, can no longer be used for a few months to a year or so. Some people say that battery manufacturers cut corners and materials, only focusing on profit, not quality. In fact, when it comes to this, I believe that many battery producers are also full of grievances. "The quality of the battery is not as good as before. This is really not bad for the manufacturer." The quality of the battery is not as good as before. We cannot rule out that some companies fiddle with the battery in order to obtain more benefits. However, the battery market is so huge that it is impossible for every company to do so. So now the battery is generally not as good as before, why?



Why do lead-acid batteries have a short lifespan?


1. Lead-acid batteries will be affected by the degree of charging. Generally, when the battery is overcharged, some gas will be folded out, which will greatly affect the active material of the plate and directly cause the active material to fall off. Moreover, the positive electrode alloy will also be severely corroded, which will shorten the overall service life of the battery.


2. Temperature also has a certain impact on the life of lead-acid batteries. Everyone knows that when the temperature of lead-acid batteries rises by one degree, the internal cycle of the battery will increase by more than 5. Excessive temperature will cause the vulcanization of the batteries. Capacity is lost and life is affected. If the discharge capacity can be kept unchanged, the depth of discharge will decrease when the temperature rises, and the overall life expectancy will not be affected too much.


3. The concentration of sulfuric acid inside the lead-acid battery will also affect the service life. When the concentration increases, it is beneficial to the capacity of the positive plate, but it may cause certain corrosion to the grid. If the lead dioxide falls off Then the life of the battery cycle will inevitably decrease.


4. The discharge density of the lead-acid battery will also affect the service life. The service life of the battery will be reduced if the density increases, and it will also cause water loss inside the battery, which will greatly affect the service life.


The service life of the battery is related to the design and manufacture of the battery and the correct use and maintenance of the customer. How to properly and effectively maintain the battery pack?


In order to ensure the communication safety of the base station battery pack, in addition to routine maintenance, it is also necessary to test the discharge capacity of the battery pack.


ENS-3018DC Battery Charge and Discharge Tester can be used to quickly solve the battery check discharge test, capacity test, and daily maintenance of the battery pack. The instrument can monitor the battery voltage, discharge current, discharge time, discharge capacity and other parameters during the discharge process in real time; it is suitable for the activation discharge of various batteries, the discharge of the initial charge of the battery, the maintenance discharge of the battery, and it can also check the storage capacity of the battery. Electrical performance and load capacity, etc.; with the advantages of easy operation and safe discharge, it is an ideal choice for battery test operation and maintenance in communication base stations, substations, rail transit, hydropower stations, and UPS computer rooms.
