The weather is getting cooler, people began to add clothes to keep warm, in case of catching a cold. Likewise, cars break down in one way or another as the seasons change.
After being exposed to the sun and rain in summer, the connection of the car battery is likely to have oxidation and other failures. The battery is an important energy storage device on the car. It supplies power for all electronic systems on the vehicle. Electricity will cause the entire vehicle to be paralyzed. Therefore, the maintenance and maintenance of car batteries has become very important.
two batteries
The batteries used in general cars are lead-acid batteries. There are two types of common lead-acid batteries, one is water-filled lead-acid batteries, and the other is maintenance-free lead-acid batteries. At present, the batteries used in more than 80% of the models on the market are maintenance-free lead-acid batteries.
Water-added lead-acid batteries: The plates of ordinary batteries are composed of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. Its important advantages are stable voltage and low price; its disadvantages are low specific energy (that is, the electric energy stored per kilogram of battery), short service life and frequent daily maintenance.Also read:https://www.aimeno.com/lithium-battery-pack/195.html
Maintenance-free lead-acid battery: Due to its own structural advantages, the maintenance-free battery consumes very little electrolyte, and basically does not need to add distilled water within its service life. It also has the characteristics of shock resistance, high temperature resistance, small size and small self-discharge. The service life is generally twice that of ordinary batteries. There are also two types of maintenance-free batteries on the market: the first one does not require maintenance during use after adding electrolyte once at the time of purchase (adding supplementary liquid); the other is that the battery itself has been filled with electrolyte and sealed when it leaves the factory. The user cannot add refill at all.
