Speaking of the car's battery, the majority of car owners will not be too strange, but if you specifically mention the type of car battery, the parameters of what, may not be clear. In most cases, you can only listen to 4S shop or garage repair master The opinion, and some of the batteries that need to be maintained, no one can remind you to carry out maintenance, the battery life can be shortened a lot.
The mainstream car batteries are roughly divided into the following types: Dry-charged lead-acid batteries, commonly known as 'ordinary batteries (not maintenance-free)' 'water batteries'. Because they are completely dry at the factory, they need to be added with electrolyte. Wait 20-30 minutes to use it. But this battery also has obvious shortcomings, that is, it is bigger in size and weight, and it needs regular maintenance. Adding electrolyte is very troublesome for the average consumer. Now small car It is used very little. This kind of battery has a maintenance hole at the top of the battery, and the price is relatively cheap. In the case of proper maintenance, the life is generally 2-4 years.
Valve-regulated sealed lead-acid battery, also known as 'maintenance-free battery'. This battery does not require maintenance from the factory to the end of life, the advantage is maintenance-free, but also has the characteristics of shock resistance, high temperature resistance, small size, but the price is relatively dry The type of lead-acid battery is higher. Nowadays, the small car basically uses this kind of battery. This kind of battery is more expensive than the dry-charged lead-acid battery, and its life is generally 2-4 years.
Lean valve-regulated battery is commonly known as 'AGM battery'. AGM has better overall performance, and the charge-discharge cycle is 3-4 times that of ordinary lead-acid batteries, and it can support higher load and energy recovery functions of automobiles. Mostly used in high-end cars with energy recovery system and start-stop function.
Generally speaking, AGM batteries are not resistant to high temperatures and are usually not placed in the engine compartment. If placed in the engine compartment, it must be ensured that there is sufficient heat dissipation in the cabin, otherwise it will shorten its life. Its price is more expensive than lead-acid batteries, life expectancy Usually in 4-6 years.
The rich liquid type battery is commonly known as 'EFB battery'. EFB has the characteristics of low cost and wide temperature range. The overall performance can meet the requirements of start-stop system, but it is not suitable for vehicles with energy recovery system. Japanese cars use EFB batteries. Their price is more expensive than lead-acid batteries, and their life expectancy is usually 4-6 years.
Lithium-ion batteries are commonly known as 'lithium batteries'. Lithium batteries have the advantages of small size and light weight; the disadvantages are high and the safety is relatively poor. Therefore, lithium batteries are mainly used in high-performance cars and sports cars, and now new energy vehicles are big. Part of the lithium battery used. Its life is usually 5-8 years, the price is also the most expensive of these batteries.
According to this, the ordinary car is suitable for the maintenance-free battery. The automatic start-stop car selects the AGM battery or the EFB battery according to the battery position. The car battery is not recommended to be replaced by itself. Some merchants will not guarantee the car battery that is replaced by itself. Online appointment of auto repair shop, can replace car battery faster and more convenient.
