Definition

The plates of ordinary batteries are composed of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. Its main advantages are stable voltage and low price; its disadvantages are lower specific energy (ie, the energy stored per kilogram of battery), short service life, and frequent daily maintenance.

Car battery, also called accumulator, is a kind of battery. Its working principle is to convert chemical energy into electrical energy. Generally speaking, the battery is a lead-acid battery. That is, a battery mainly made of lead and its oxide, and the electrolyte is a sulfuric acid solution.

Features

1. The advantage is stable voltage
2. Cheap
3. The disadvantage is that the specific energy is low (that is, the electrical energy stored per kilogram of battery)
4. Short life
5. Frequent daily maintenance

The device that converts chemical energy into electrical energy is called a chemical battery, and is generally called a battery for short. After discharging, the internal active material can be regenerated by charging-storing electrical energy as chemical energy; chemical energy is converted into electrical energy again when discharging is required. This type of battery is called a secondary battery and also called a secondary battery.

The so-called battery is an electrochemical device that stores chemical energy and releases electrical energy when necessary.

Maintenance

1. Wipe the outside of the battery with a damp cloth, and wipe off dust, oil, and white powder on the panel and pile head (that is, the positive and negative poles) that are likely to cause leakage. In this way, the battery is often scrubbed, and the pile head of the battery will not accumulate white acid-eroded powder, and its service life will be relatively long.

2. Open the battery water cap and see if the water level is in the normal position. Generally, there will be upper and lower limit markings on the side of the battery for your reference. If it is found that the water level is lower than the subscript line, distilled water must be added. If distilled water is not available immediately, filtered tap water can be used as an emergency. Do not add too much water, the standard is to add between the upper and lower marking lines.

3. Check if the battery is charging normally. If you have a three-use meter, after starting the engine, measure the voltage between the two poles of the battery. It must be more than 13V to be normal. If you find that the charging voltage is too low, you need to ask a professional to overhaul the charging system. If you do not have a three-use meter, you can use the visual inspection method: After the engine starts, open the battery and add the water cap to see if there are bubbles in each cell. The normal condition is that there are bubbles coming out of the water constantly, and the more you add oil, the more you will; if you find no bubbles, it is likely that the charging system is defective. Special attention should be paid to the occurrence of hydrogen during this test, so do not smoke during the test to avoid the danger of explosion and fire.
