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. Lead storage 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 used in the car (commonly known as the battery) is a 12V battery pack with 6 lead-acid batteries connected in series.

Storage Battery is a device that directly converts chemical energy into electrical energy. It is a rechargeable battery designed to recharge through a reversible chemical reaction. It usually refers to a lead-acid battery, which is a type of battery , Belongs to the secondary battery. Its working principle: When charging, use external electric energy to regenerate internal active materials, store electric energy as chemical energy, and convert chemical energy into electric energy again when it needs to be discharged, such as cell phone batteries commonly used in life.

The difference between conventional batteries and AGM batteries: AGM batteries are sealed, and there is an exhaust valve on the battery cover. During normal use, no water is required. Conventional batteries are non-sealed, and the electrolyte can be seen by opening the filling cover, and it is necessary to frequently replenish water during use. Compared with batteries of the same specification, the price is higher, but it has the following advantages: 1. The cyclic charging capacity is 3 times higher than that of lead-calcium batteries and has a longer service life. 2. Have higher capacitance stability during the whole life cycle. 3. Low temperature starting is more reliable.

Maintenance-free battery, as the name suggests, the biggest feature is "maintenance-free". Compared with lead-acid batteries, its electrolyte consumption is very small, and there is basically no need to supplement distilled water during the service life. It also has the characteristics of shock resistance, high temperature resistance, small size, and small self-discharge. Of course, its price will be more expensive than lead-acid batteries. As for the service life, the recommended replacement period for maintenance-free batteries under normal conditions is about 3 years, which is equivalent to lead-acid batteries. In order to avoid daily maintenance and maintenance, the design of the exhaust system is significantly different from that of lead-acid batteries, so theoretically, it is not necessary to add distilled water or electrolyte frequently. In addition, the housing of maintenance-free batteries is generally closed, and unless there are professional tools and techniques, the general owner cannot check and repair by himself. Although the maintenance-free battery is called "maintenance-free", it is not completely left unattended. The manufacturer recommends checking the battery every 30,000 kilometers and performing maintenance every 80,000 kilometers. However, there are currently very few 4S shops or repair shops that can perform this operation, and the service life of the maintenance-free battery is relatively fixed. Under normal use, it should be replaced in 2-3 years, and there is nothing to extend it. The way of life.

Ordinary batteries are also called lead-acid batteries. Its electrodes are composed of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. The main advantages are stable voltage and low price; the disadvantages are low specific energy (that is, the electric energy stored per kilogram of battery), short service life and frequent daily maintenance. Old-fashioned ordinary batteries generally have a lifespan of about 2 years, and it is necessary to regularly check the height of the electrolyte and add distilled water. However, with the development of technology, the current life of ordinary batteries has become longer and maintenance is easier. The most obvious feature of a lead-acid battery is that there are 6 unscrewed plastic sealing covers on the top, and there are vent holes on the top. These sealing caps are used for filling, checking electrolyte and exhaust gas. Theoretically speaking, lead-acid batteries need to be checked for the height of the electrolyte during each maintenance, and distilled water should be added if there is a shortage. But with the upgrading of battery manufacturing technology, the maintenance of lead-acid batteries is no longer complicated. In normal use, there is no need to add electrolyte or distilled water to lead-acid batteries for 2-3 years. In other words, for the average car owner, if you don't take special maintenance on the lead-acid battery, it can also work normally for 2-3 years, and the lifespan is basically the same as the maintenance-free battery.

Batteries are mainly divided into three types: lead-acid batteries, dry-charge batteries and maintenance-free batteries. Among them, the batteries used in passenger cars that we all are more familiar with are basically lead-acid batteries and maintenance-free batteries. At present, most of the models sold on the market use maintenance-free batteries, and most Japanese cars, even these high-end Japanese cars such as Lexus and Infiniti, also use non-maintenance-free batteries, that is, lead-acid batteries.
