The advantages and disadvantages of storage batteries

1. Dry-charged lead-acid storage batteries are called dry-charged storage batteries because they are completely dry and have no electrolyte when they leave the factory. Because it needs to add electrolyte when using, it is commonly called water battery. Its advantage is that the negative plate has a high power storage capacity. In a completely dry state, it can save the obtained power within two years, so it is very convenient for storage and transportation. You only need to add electrolyte when using it, and wait for 20-30 minutes. Can be used. The price is relatively cheaper. The disadvantage is that the storage of the same ampere hour (battery capacity unit) is larger in volume and weight, and regular maintenance is required to add electrolyte, which is very troublesome for general consumers. Now it is basically only applied to trucks and buses.

   
   

　　2. Valve-controlled sealed lead-acid storage batteries, also known as maintenance-free storage batteries. As the name implies, the battery does not need to be added for maintenance from the factory to the end of life. The advantages are obvious. Firstly, it is maintenance-free, and secondly, it also has the characteristics of shock resistance, high temperature resistance, small size, and low self-discharge. The service life is generally longer. The disadvantage is that the price is relatively high. Now basically all passenger cars use this kind of battery. As the price difference of maintenance-free storage batteries has been further compressed in recent years, more and more buses and trucks are now using maintenance-free storage batteries.

　　3. Lithium-ion batteries. The advantages of lithium batteries are small size and light weight. Disadvantages are expensive and relatively poor in security. Because of the above characteristics, it is mainly used in high-performance cars and sports cars.
