What are the types of car batteries?

There are two types of storage batteries for automobiles. One is maintenance-free batteries, and the other is ordinary batteries. Ordinary batteries are also called lead-acid batteries. The important advantage of this battery is its low price and relatively stable voltage. The disadvantage is also obvious, frequent daily maintenance is required. Regularly check the height of the electrolyte and add distilled water. Maintenance-free battery. Do not periodically check the height of the electrolyte and add distilled water during the service life. At the same time, it also has many advantages such as small size, high temperature resistance and shock resistance. This kind of battery is simple and easy after all. The disadvantage is that the price is more expensive than ordinary batteries. If you want to increase the service life of the battery, you must pay attention to the usual maintenance and care, and do not have the habit of harming the battery. When the battery life is about to expire, it usually feels that the car's headlights are not brighter than before, or the car can't fire when the weather is cold. If a similar situation occurs, check whether it is time to change the battery. Generally speaking, the original battery of a new car can be used for 3-4 years, but after a replacement, it usually needs to be replaced in about 2 years. The life of a car battery is related to various factors such as vehicle conditions, road conditions, driver’s habits, and maintenance status. People who lack common sense in vehicle use and do not pay attention to maintenance may be damaged in half a year. Generally, the newer the car, the more efficient the battery is. The motor is easy to use, battery saving, and the generator is easy to use. The battery can be fully charged. After the car is old, especially after the two large motor generators are replaced, especially when the original parts are not replaced, the battery can be replaced The time is even shorter. The device that converts chemical energy into electrical energy is called a chemical battery, generally referred to as a battery for short. After discharging, the internal active material can be regenerated by charging to store electrical energy as chemical energy; when it is to be discharged, chemical energy is converted into electrical energy again. This type of battery is called a storage battery (Storage Battery), also called a secondary battery. The so-called storage battery is an electrochemical device that stores chemical energy and releases electrical energy when necessary. Storage Battery (Storage Battery) is a device that directly converts chemical energy into electrical energy. It is a battery designed for rechargeability. It is recharged through a reversible chemical reaction. It usually refers to a lead-acid battery, which is a type of battery. Belongs to secondary battery. Its working principle: When charging, use external electric energy to regenerate internal active materials, store electric energy as chemical energy, and then convert chemical energy into electric energy output when discharging, such as cell phone batteries commonly used in life. It uses a lead substrate grid filled with spongy lead (also called a grid) as the negative electrode, and a lead substrate grid filled with lead dioxide as the positive electrode, and uses dilute sulfuric acid with a density of 1.26--1.33g/mlg/ml as the electrolyte. When the battery is discharging, metallic lead is the negative electrode and an oxidation reaction occurs to produce lead sulfate; the lead dioxide is the positive electrode and a reduction reaction occurs to produce lead sulfate. When the battery is charged with direct current, elemental lead and lead dioxide are respectively generated at the two poles. After removing the power source, it returns to the state before discharge, forming a chemical battery. The battery can be charged and discharged repeatedly. Its cell voltage is 2V. The battery is a battery pack composed of one or more cells, referred to as storage battery, the most common is 6V, and there are 2V, 4V, 8V, 24V storage batteries. For example, the battery (commonly known as the battery) used in a car is a 12V battery pack with 6 batteries connected in series.
