How to charge the car battery? Common Problems When Charging
If you own a car and have driven it for many years, but in the last month or two you may have gone on vacation or don’t want to drive it because of other things, then when you start the car again, you may encounter a situation where the car battery is dead. You can only charge it in time to drive normally.
How to use the battery charger to charge the car battery?
1, according to the voltage of the battery, choose the charger 12v or 24v gear, choose the 12V gear for the battery 12V, and choose the 24V gear for the battery 24V.
2, first clip the red clip on the positive terminal of the battery and then clip the black clip on the negative terminal of the battery. Be clamped to avoid poor contact and never clamped backward.
Battery positive and negative: regular manufacturers of batteries red line for the positive pole, black line for the negative pole. For informal manufacturers of batteries, the red line for the positive pole, and the negative pole can be any color. Vehicle battery: positive pole (+), negative pole (-), when you can not see the plus or minus sign, the battery column thick is the positive pole, and thin is the negative pole.
3, the charger power plug into a standard voltage plug board.
4, press the charger switch, turn the charging display light on red, and start charging. The red light turns green indicating that the battery is fully charged.
5, close the charger switch and unplug the charger. Remove the negative clip first, then remove the positive clip.
Before using the charger to charge the battery, we make sure that the charging current meets the battery requirements.
How much current is appropriate for charging a car battery?
The normal charging current of a car battery is 1.5a-2.5a The charging current of a battery is related to the capacity of the battery, which is usually one-tenth of the battery capacity (error 0.5). For example, the normal charging current of a 12v20ah battery is 1.5a-2.5a Do not adjust to too high a current output, otherwise, it will damage the car battery.
What is the car battery charging voltage?
The car battery charging voltage is between 13~15v.
1, 12v car battery charging voltage is around 13.8v.
2、The normal voltage before the car starts is between 11.8V~14.8V.
3、Check the battery usage regularly, once the battery voltage is lower than 10.8V, it needs to be charged in time.
4、The battery voltage is too high or too low, which will cause certain effects. If the voltage is too low, it is difficult or even impossible to start the car; if the voltage is too high, the battery may be damaged.
Car battery charging precautions
When charging, open the battery refill hole cover and keep the room well ventilated to avoid the danger caused by releasing a large amount of gas at the end of charging. Forbid to set off fireworks when charging to prevent the gas released during charging from burning.
When charging, first connect the positive and negative cables between the battery and the charger, and then connect the charger power. Otherwise, sparks may be generated when connecting the cables, leading to explosive accidents. The charger should not be used in direct sunlight or outdoor rain, nor should it work in a large dusty or corrosive gas environment.
How long does it take to charge a car battery?
There are two types of charging time for car batteries: fast charging saves time and takes only 3 to 5 hours. Slow charging has a charging time of 10 to 15 hours. A severely depleted battery must be charged slowly, otherwise the charging time and insufficient charging capacity will directly affect the vehicle’s driving performance.
To maintain your vehicle battery, it is important to develop good power habits. For example, you should not listen to the radio loudly when the engine is off, charge your cell phone, or use the charge pump. Otherwise, over time, it is easy to cut off the power and greatly shorten the life of the battery.
In addition, if you do not use the car for a long time, such as 20 days or a month, you should disconnect the battery cable or start the vehicle for a few dozen kilometers every two weeks to charge the battery to ensure normal battery use.
Causes of sudden dead car battery
If the car is suddenly dead under normal use, it needs to be considered from the following aspects.
1. whether you forget to turn off lights, air conditioners, radio stations, and other electricity-using devices after using the vehicle.
2. the use of high-powered electrical appliances at idle speed, such as high-powered stereos.
3. the car starts too often.
4. other causes of battery leakage.
The battery has a service life, usually in use to pay more attention to the battery is healthy, if there is leakage and other phenomena, then it means that the battery should pay attention to timely repair or replacement.
Car battery maintenance methods
1. regular driving: the vehicle has been parked for a long time so that the electricity in the battery slowly decreases, after a long time, it is easy to have a power loss phenomenon, every few days you can drive out for a period to charge the car battery, try to keep the car battery in a fully charged state, each drive is best to keep it above 20 minutes.
2. try not to use electricity after the vehicle is off: in the off state, the car consumes the power of the battery, if used for a long time, it may deplete the power in the battery, the phenomenon of not being able to start, it is recommended that the owner does not use electric devices after the vehicle is off.
3. regularly clean the battery: in the daily driving process need to clean the car battery, you can use a cloth to wipe the panel, positive and negative two pole head dust, oil, white powder and other easy to cause leakage dirt clean, do not use a wet cloth, if personal treatment is not good, it is recommended that owners go directly to the 4s store or a professional repair store for processing.
4. regularly replace the battery: car battery has a certain period of use, lead-acid batteries are generally three 3-5 years, lithium iron phosphate batteries for 8-10 years, the battery will be used for a long time in performance decline, so the need for owners to replace the car battery promptly.
