The capacity unit of the battery is ampere hour, referred to as ampere hour (AH), which means the capacity number of the battery released at the end of the specified discharge time at the condition of constant current or constant power discharge at the specified discharge rate.
For a battery with a discharge rate of 10 and a capacity of 100AH, the discharging current of 10A is 10H and the discharged capacity is 100AH. ,
8W is the power. There are two parameters of the battery: battery voltage U, unit V (V), and battery capacity C, where the unit of C is AH (ampere hour).
Assuming a 6V/10AH battery, the amount of power it can provide is: 6V*10AH=60VAH, which can provide power for 8W lamp tube T=60/8=7.5 hours. This is an ideal situation, but the actual time is shorter.
Power supply time calculation formula:
T = K * U * C/P
Where: P -- power of electrical appliances, K -- power coefficient, usually between 0.7 and 0.9
Battery under specified conditions (including discharge intensity, discharge current and discharge termination voltage) discharge quantity or discharge time is called battery capacity, unit A·h or A·min. Automobile accumulator is a reversible dc power supply, which can convert chemical energy into electrical energy and electrical energy into chemical energy.
During engine start-up, it supplies power to the starting system and ignition system.
When the engine stops running or runs at a low idle speed, it powers the car's electrical equipment.
When demand exceeds the output of the charging system, it provides the current for a limited period of time.
The accumulator also absorbs the instantaneous overvoltage in the circuit to maintain the stability of the voltage of the automobile electrical system and protect the electronic components.
Batteries do not use for a long time, it will slowly self-discharge, until scrapped. Therefore, the car should be started at regular intervals to charge the battery. Another way is to pull out the two electrodes on the battery, it is necessary to pay attention to the electrode column from the positive and negative two electrode line, to pull out the negative line, or remove the negative and the car chassis connection. Then pull out the other end with a positive sign (+), the battery has a certain service life, to a certain period of time to be replaced. When changing, should follow afore-mentioned order likewise, when connecting electrode line however, order is just opposite, first connect positive pole, connect negative pole again next.
When the ammeter pointer shows insufficient power storage, to charge in time. The storage capacity of the battery can be reflected on the instrument panel. Sometimes in the road found that the power is not enough, the engine and flame out start not, as a temporary measure, you can ask for help from other vehicles, with their vehicles to start the vehicle battery, the two battery negative and negative connected, positive and positive connected.
The density of electrolyte should be adjusted according to the standards in different regions and seasons.
When the electrolyte is deficient, distilled water or special rehydration and nanometer carbon sol cell activator should be added. Avoid drinking pure water instead. Because pure water contains a variety of trace elements, the battery will cause adverse effects.
When starting the car, continuous use of the starter causes the battery to be damaged by excessive discharge. The correct way to use is to start the car each time the total time is not more than 5 seconds, again start interval is not less than 15 seconds. In the case of multiple starts without the car should be from the circuit, ignition coil or oil circuit and other aspects of the cause.
Daily driving should often check whether the small hole on the battery cover ventilation. If the small hole of the battery cover is blocked, the hydrogen and oxygen produced cannot be discharged, and when the electrolyte expands, it will break the battery shell and affect the battery life.
Check the positive and negative levels of the battery for signs of oxidation. Hot water can often be poured over the wire connections of the batteries.
Check whether there is aging or short circuit in each part of the circuit to prevent the battery from being decommissioned in advance due to excessive discharge. [1]
1. Excessive discharge
2. Storage of the battery for a long time (without charging during storage)
3. Cannot be charged by car engine
4. No electrolyte
5. Too high specific gravity of electrolyte
Charge at high temperature
7. Contamination by contaminants (e.g. hydrochloric acid, seawater, organic acid, etc.)
8. Add too much current when the battery is charged
9. The electrode plate deformation causes the positive plate and the coated plate to contact each other, resulting in a short circuit phenomenon
10. Deposit dirt on the upper and lower parts of the plate, causing short circuit
Just pay attention to avoid the above points, your battery life will increase accordingly. [2]
Electrolyte level should always be kept between Max and min, check once a month, and depending on the level of decline, appropriate supplement distilled water (pure water), do not add acid.
When the battery voltage is insufficient and the light is dim and the starting is weak, it should be charged out of the car in time.
Prevent the battery overcharge or long-term loss of power, overcharge will make active substances fall off, loss of power will make the plate vulcanization, to ensure that the regulator voltage can not be too high or too low.
In the process of use, should always check whether the vent is smooth, to prevent the battery deformation or burst.
Batteries should be kept away from heat source and open fire. Ventilation should be maintained during charging and use to prevent burning and injury.
To prevent the battery from discharging for a long time and a large current, the start-up time for each use shall not be more than 5 seconds, and the two consecutive start-up times shall be separated by 10-15 seconds.
The battery should be firmly installed on the car to reduce vibration.
Often check whether the battery cable is solid, all live joints, must keep good contact, prevent spark, cause the battery explosion. The oxides and sulfates produced by the clips must be scraped clean and coated with vaseline to prevent further corrosion.
Often clear the battery cover of dust and dirt and overflow of the electrolyte, keep clean and dry, prevent self-discharge.
Sealing gum cracking to repair in time.
Car driving in the cold region, to avoid complete discharge of the battery, so as to avoid freezing electrolyte.
