The capacity of the battery with a voltage of 12V includes 2.2AH, 7AH, 14AH, 17AH, 24AH, 32AH, 45AH, 60AH, 80AH, 105AH, 120AH, 160AH, and 198AH.

The device that converts chemical energy into electrical energy is called a chemical battery, commonly referred to as a battery. After discharge, the internal active substances can be regenerated by charging - storing electrical energy as chemical energy; Convert chemical energy into electrical energy again when discharge is required. This type of battery is called a Storage Battery, also known as a secondary battery.

A battery is an electrochemical device that stores chemical energy and releases electrical energy when necessary.

The amount of electricity or duration of discharge discharged by a battery under specified conditions (including discharge intensity, discharge current, and discharge termination voltage) is called the battery capacity, in units of A · h or A · min. A car battery is a reversible DC power source that can convert chemical energy into electrical energy, as well as electrical energy into chemical energy. It is connected in parallel with a generator.

During engine start-up, it supplies power to the starting system and ignition system.

When the engine stops running or runs at low idle, it supplies power to the car's electrical equipment.

When the electricity demand exceeds the output of the charging system, it provides current during this limited period of time.

The battery also absorbs instantaneous overvoltage in the circuit to maintain the stability of the automotive electrical system voltage and protect electronic components.

If a battery is not used for a long time, it will slowly discharge on its own until it is scrapped. Therefore, the car should be started at regular intervals to charge the battery. Another method is to unplug the two electrodes from the battery. It is important to note that the positive and negative electrode wires should be unplugged from the electrode posts. First, unplug the negative electrode wire or remove the connection between the negative electrode and the car chassis. Then unplug the other end with the positive symbol (+), the battery has a certain service life and needs to be replaced at a certain period of time. When replacing, the above order should also be followed, but when connecting the electrode wires, the order is exactly the opposite: first connect the positive electrode, and then connect the negative electrode.

When the ammeter pointer shows insufficient battery storage, it should be charged in a timely manner. The storage capacity of the battery can be reflected on the dashboard. Sometimes during the journey, it is found that the battery level is insufficient and the engine cannot be started. As a temporary measure, you can seek help from other vehicles and use their batteries to start the vehicle. Connect the negative and negative terminals of the two batteries, and the positive and negative terminals.

The density of the electrolyte should be adjusted according to standards for different regions and seasons.

When the electrolyte is depleted, distilled water or specialized electrolyte should be supplemented, and nano carbon sol battery activators should be added. Avoid using purified drinking water instead. Because pure water contains multiple trace elements, it can have adverse effects on batteries.

Uninterrupted use of the starter during car startup can cause damage to the battery due to excessive discharge. The correct usage method is to start the car for a total time of no more than 5 seconds, and the interval between restarts should not be less than 15 seconds. In the case of multiple starts without starting the vehicle, the cause should be identified from other aspects such as the circuit, ignition coil, or oil circuit.

Regularly check whether the small hole on the battery cover is ventilated during daily driving. If the small hole in the battery cover is blocked, the generated hydrogen and oxygen cannot be discharged. When the electrolyte expands, it will break the battery casing and affect the battery life.

Check for signs of oxidation on the positive and negative terminals of the battery. You can often use hot water to water the electrical connections of the battery.

Check for aging or short circuits in various parts of the circuit to prevent premature retirement of the battery due to excessive discharge.

1. Excessive discharge

2. Long term storage of batteries (not fully charged during storage)

3. Cannot be charged through the car engine

4. No electrolyte

5. The specific gravity of the electrolyte is too high

6. Charging under high temperature conditions

7. Contamination by pollutants (such as hydrochloric acid, seawater, organic acids, etc.)

8. Apply excessive current when charging the battery

9. The deformation of the electrode plate causes the positive electrode plate to come into contact with the cladding plate, resulting in a short circuit phenomenon

10. Deposition of dirt on the upper and lower parts of the electrode plate, causing a short circuit

As long as you pay attention to avoiding the above points, the service life of your battery will correspondingly increase.

The electrolyte liquid level should always be maintained between max and min, checked monthly, and depending on the decrease in liquid level, distilled water (pure water) should be added appropriately, and acid should not be added.

When the voltage of the battery is insufficient, the lights are dim, and the starting is weak, it should be charged outside the vehicle in a timely manner.

To prevent overcharging or long-term depletion of the battery, overcharging can cause the active substance to fall off, and depletion can cause the electrode plate to vulcanize. It is necessary to ensure that the voltage of the regulator is not too high or too low.

During use, it is necessary to regularly check whether the exhaust hole is unobstructed to prevent the battery from deforming or bursting.

Batteries should be kept away from heat sources and open flames, and ventilation should be maintained during charging and use to prevent burns and injuries.

To prevent long-term high current discharge of the battery, the starting time for each use should not exceed 5 seconds, with a continuous starting time of two times and an interval of 10-15 seconds between them.

The battery should be installed firmly on the car to reduce vibration.

Regularly check if the battery connection wires are secure, and all movable joints must maintain good contact to prevent sparks from generating and causing battery explosions. The oxides and sulfates generated by the battery clip must be scraped off and coated with Vaseline to prevent further corrosion.

Regularly remove dust, dirt, and spilled electrolyte from the battery cover, keep it clean and dry, and prevent self discharge.

The cracking of the sealing adhesive should be repaired in a timely manner.

When driving in cold regions, it is important to avoid complete discharge of the battery to prevent the electrolyte from freezing.
