Lead-acid battery capacityCapacity (AH) is the energy size unit of the battery, and is also the main factor in the price of the battery. The electrodes of the battery are mainly made of lead and its oxides, and the electrolyte is a battery of the sulfuric acid solution. English: Lead-acidbattery. In the discharge state, the main component of the positive electrode is a lead, the negative electrode is main component of lead; the main components of the positive and negative electrode are leaded to the lead of sulfate. Divided into an exhaust battery and a maintenance lead-acid battery.
The battery is mainly composed of a tubular positive electrode plate, a negative electrode plate, an electrolyte, a partition, a battery tank, a battery cover, a pole column, an injection cover, and the like. The electrode of the exhaust battery is composed of the oxide of lead and lead, and the electrolyte is an aqueous solution of sulfuric acid. The main advantage is that the voltage is stable, the price is cheap; the disadvantage is that the energy is low (i.e., electrical energy stored per kilogram battery), the service life is short of usual maintenance. Old-style ordinary battery is in a general life of about 2 years, and the height of the electrolyte is required regularly and add distilled water. However, with the development of technology, the life of lead-acid batteries has become longer and the maintenance is also simpler.
The lead-acid battery is most obvious that the top there is an unbeatable plastic sealing cover, and there is a vent hole. These liquid baffles are used to fill the pure water, examine electrolyte and discharge gas. According to theory, lead-acid batteries need to check the density and liquid level height of the electrolyte during each maintenance, if there is a lack of distilled water. However, with the upgrading of battery manufacturing technology, lead-acid batteries are developed into lead-acid-free maintenance batteries and colloidal maintenance batteries, lead-acid batteries are used in use without adding electrolytes or distilled water. It is mainly used to generate oxygen to reach an oxygen circulation at the negative electrode absorption to prevent moisture. The lead-acid hydrolybells are used in tractors, tricycles, automotive starts, etc., while maintenance-free lead-acid batteries are widely used, including uninterruptible power supplies, electric vehicle power, electric bicycle batteries. The lead-acid battery is divided into constant current discharge (such as uninterrupted power) and instant discharge (such as a car start battery) according to the application needs.
What are the lead-acid battery model?
Classification of lead-acid batteries
1) Ordinary battery; polar plate of ordinary battery is made of lead and lead oxide, the electrolyte is an aqueous solution of sulfuric acid. Its main advantage is that the voltage is stable, the price is cheap; the disadvantage is that the battery is low (that is, the battery stored per kilogram of battery), the service life is short and frequent in daily maintenance.
2) Drytaking battery: It is a full name is a dry-loaded lead-acid battery. Its main feature is that the negative electrode plate has a high storage capacity. In the fully dry state, it can save the resulting power in two years, use When you only need to add an electrolyte, you can use it for 20-30 minutes.
3) Maintenance-free battery: Maintenance-free battery due to its own advantages, the consumption of the electrolyte is very small, basically no need to supplement distilled water in the service life. It also has the characteristics of high temperature resistance, high temperature, small size and small discharge. The service life is generally twice the ordinary battery. There are two maintenance-free batteries on the market: the first one is not needed in use after purchasing (adding a supplement); the other is that the battery itself is shipped with the electrolyte and sealed The user cannot add a supplement at all.
How to see the lead-acid battery model
According to the mechanical industry standard JB2599-1985, the lead-acid battery model is composed of three parts, and the content and arrangement are as follows:
Serped single battery number - battery type - battery characteristics - battery capacity
(1) Number of series single lines
The number of series single cells refers to the number of monarch batteries contained in the battery assembly and is represented by a Arabic number.
(2) Battery type
According to its main use, use a Chinese Pinyin letter, the start-type lead-acid battery "Q" said "Q", the code "Q" is the first Chinese Pinyin letter of "starting". (M is a battery of motorcycle, the JC unmarine battery, HK is the air storage battery, D represents the electric vehicle battery, and F represents the valve controlling battery.)
(3) Battery characteristics
The battery is characterized by an additional section, which is represented by a Chinese Pinyin letter. It is only a feature of the products of similar purposes, while in the model, it must be differentiated. When the product has two features, the two codes should be signed in accordance with the order 2-2.
Lead-acid battery rated capacity
The rated capacity refers to the rated capacity of 20H discharge rate. It is represented by Arabic numbers, and the unit is A ¡¤ H. It may be omitted in the model. Sometimes a special performance is indicated by a letter behind the rated capacity, such as "G" means a high starting rate, "S" means a plastic housing, "D" means a low temperature startability.
