What Are the Types of Automotive Batteries?
1 Answers
Nowadays, automotive starting batteries generally include the following types: Dry-charged Lead-Acid Battery: This type is called a dry battery because it is completely dry without electrolyte when it leaves the factory. Since it requires the addition of electrolyte for use, it is commonly known as a water battery. Its advantage is that the negative plate has a high capacity for storing electricity, and it can retain the stored charge for up to two years in a completely dry state, making it very convenient for storage and transportation. To use it, you only need to add electrolyte and wait for 20-30 minutes before it is ready. It is also relatively cheaper. The downside is that it requires regular maintenance and the addition of electrolyte, which can be quite troublesome for the average consumer. Currently, it is mainly used in trucks and buses. Valve-Regulated Sealed Lead-Acid Battery: Also known as a maintenance-free battery. As the name suggests, this battery does not require any liquid maintenance from the time it leaves the factory until it is scrapped. The advantages are obvious: first, it is maintenance-free; second, it is resistant to vibration, high temperatures, compact in size, and has low self-discharge. It generally also has a longer lifespan. The drawback is that it is relatively more expensive. Currently, almost all passenger cars use this type of battery. With the price gap of maintenance-free batteries narrowing in recent years, more and more buses and trucks are also starting to use maintenance-free batteries. Lithium-Ion Battery: The advantages of lithium batteries are their small size and light weight. The disadvantages are their high cost and relatively lower safety. Due to these characteristics, they are mainly used in high-performance cars and sports cars.
