What kinds of car batteries are there? What are the main features?

Currently, there are three main types of car batteries: ordinary batteries, dry-charge batteries, and maintenance-free batteries.

1. Ordinary battery: The plate of an ordinary battery is composed of lead and lead oxide, and the electrolyte is an aqueous solution of sulfuric acid. Its main advantages are stable voltage and low price; disadvantages are low specific energy (that is, the electric energy stored per kilogram of battery), short service life and frequent routine maintenance.

2. Dry-charged battery: its full name is dry-charged lead-acid battery. Its main feature is that the negative plate has a high storage capacity. In a completely dry state, it can be used within two years Save the power obtained. When using, just add electrolyte and wait for 20-30 minutes before use.

3. Maintenance-free storage battery: Due to its structural advantages, the maintenance-free storage battery consumes very little electrolyte and basically does not need to be supplemented with distilled water during its service life. It also has the characteristics of shock resistance, high temperature resistance, small size, and small self-discharge, and its service life is generally twice that of ordinary batteries. There are also two types of maintenance-free batteries on the market: the first one is to add electrolyte once at the time of purchase, and there is no need to maintain it in future use (adding supplementary fluid); the other is that the battery itself has been filled with electrolyte before leaving the factory, and If it is sealed, the user cannot add refill at all. The battery plays an important role in the use of the car. If it cannot supply power normally, the engine and the car's electrical system will follow suit or stop. Therefore, we must take good care of it at ordinary times to avoid the embarrassment that the engine cannot be started or the vehicle suddenly turns off halfway. We just need to spend a minute or two to maintain the battery every time we check the engine.
