10 important points about the car battery charger
If we want to talk about 10 important points about the battery charger, the first point is to check that car battery discharge is one of the problems that happens for various reasons and almost everyone has experienced it at least once. All batteries need a little charge to start, and if the battery is so-called “sleeping”, we need to charge the battery with the help of an external source. In this article, we are going to review the car battery charger and while reviewing different types of car battery chargers, we will also explain how to use it.
Reasons for car battery discharge
The car not starting due to the discharge of the car charge seems to be a common problem. One of the ways that has been used to solve this problem in the past is to connect to the battery of another car or in the common term “battery to battery” two cars where one battery is active and the other battery is empty. In the following, we will discuss some reasons that cause the car battery to discharge.
electricity theft
Electricity theft is one of the concerns that worries most drivers and it means that the electricity generated by the alternator is lost somewhere in the middle of the road and does not reach the engine completely. If while driving, you encounter problems such as delay in starting, dimming or skipping of front and rear lights, disconnection and connection of recording or so-called “ripping” of the engine, your car probably has electricity theft.
Alternator failure
The main task of the alternator in the car is to convert mechanical energy into electrical energy. But sometimes after 5 or 6 years, the alternator of the car becomes weak. Sometimes, due to the rupture or wear of the wiring, a defect in the belt that leads to a disruption in the production of mechanical energy, or a fuse failure due to the continuous passage of strong current, the alternator is unable to generate electrical energy and transfer it to the battery. Normally, the alternator should be able to charge the battery somewhere between 13.5 and 14.5 volts, and any value lower than this is a sign of alternator failure and a higher value causes battery failure.
Dandruff on the battery
You may look at the battery after the car does not start and see that the battery head is covered with dandruff. In this case, before any other action, clean the battery head with a wire brush and start again. Dandruff on the battery head prevents the electric current from reaching the battery.
Battery failure
Batteries have a useful life like other car components, and although you should be careful in choosing a car battery, after some time due to corrosion in the metal of the battery, we will see a malfunction of the battery. Factors such as the cables connected to the battery not being clean, or the cables not being placed on the correct pole, connecting the car battery charger for a long time and overcharging the battery, and of course low quality may lead to battery failure.
Keeping in mind that when the battery is discharged, the car will practically remain motionless and due to the fact that all car batteries are rechargeable, there are different ways to charge the car battery, the easiest of which is to use a car battery charger that can be charged at different time intervals. They charge the battery completely.
Types of car battery chargers
Car batteries are sold in different types of dry, acid and atomic, and all of them are rechargeable. The way and amount of car battery charging are among the factors that contribute to battery life. Therefore, there are two types of car battery chargers, each of which is used according to necessity, and they are as follows:
- floating charger
- trickle charger
Floating chargers are a type of car battery charger that is recommended for regular use. These types of chargers stop the charging procedure after the battery charger process is completed, even without disconnecting the charger from the battery, and in this way, the battery will not be overcharged. With this method, the useful life of the battery will increase and it will not be damaged due to charging.
trickle charger
This type of charger, unlike the previous type, does not play a role in stopping the charging routine, and in this way, the continuous use of this type of charger increases the possibility of battery damage. Battery charging methods also affect battery life. The car battery charger usually charges the battery in two different ways, which are automatic and manual.
Automatic method
In automatic charging, energy enters the battery slowly and with low amperage. After the completion of this process, the car battery charger stops the charging operation so that the battery does not get damaged and does not get hot. This method is the best method of charging, which has the most effect and the least damage.
Manual method
In this method, energy enters the battery quickly and with high amperage. This procedure continues after the battery is fully charged, and for this reason, it will gradually reduce the useful life of the battery.
How to charge the car battery?
To start, the car battery needs 12 volts of electricity. But if the charge is less than this, the alternator alone cannot help the battery. Before starting to work with the car battery charger, it is necessary to measure the level of the existing electrolyte by separating the battery houses, and if it is low, add only distilled water.
10 important points about working with a car battery charger
To start charging with the help of a car battery charger, you should pay attention to several points:
1- The charger converts electricity from a single-phase source to a current with a voltage of 12 volts by conducting an electric current of 220 volts. In this way, it is important that the output voltage of the charger is adjusted to the battery voltage. The battery connection and the car battery charger are important and you should pay attention to the positive and negative signs on the battery poles. Sometimes, instead of these two signs, the words “Pos” and “Neg” are written as abbreviations of the words “Positive” and “Negative”.
2- Make sure the connection between the battery and the cable is tight so that the current enters the battery uniformly. Keeping in mind that a current with a voltage of 220 V enters the battery through the cable, a full connection will help to receive the full current and thus increase the useful life of the battery.
3- Before connecting the charger to the battery, turn off the degree and timer of the charger and establish the connection after making sure.
4- Before connecting the battery to the charger, check the electrolyte level of all cells and if it is not high enough, just add distilled water.
5- How to connect Car battery charger is also very important. For this purpose, the negative pole of the charger, which is black, should be connected to the negative pole of the battery, and the positive and red terminal should be connected to the positive pole of the battery. With the correct connection, the battery will be charged in a certain period of time.
6- While charging the battery, you should pay attention to the temperature and also the ventilation of the environment. An increase in ambient temperature may be dangerous as an external factor and even lead to an explosion. For this reason, charge the battery in a well-ventilated room (such as an open window).
7- Although the battery is not connected to the car during charging, it is better to put a wet towel on the battery and the battery door screws to avoid danger.
8- Chargers can charge at two amperes and go up to 48 ampere-hour capacity. In this way, it will take 24 hours to fully charge the battery.
9- Do not touch the wires while charging the battery. Touching the wires will disconnect the charger from the battery pole, which can even lead to sparks and battery explosion.
10- After finishing the battery charging process, first turn off the charger and then disconnect it from the battery.
What is a jump starter?
One of the ways to charge your car battery immediately is to use a jump starter. From the name of this type of car battery charger, it is clear that by charging the car battery at once, it gives a new life to the car so that it has enough energy to start.
conclusion
In this article, which is about 10 important points about working with a car battery charger, Check the car battery charger We discussed important safety points in this regard. Recharging the battery of cars that have been finished due to the light staying on or not working, has several important steps that must be done carefully and keeping safety points in mind.
In a general view, there are two types of charging, “Manual” and “Automatic”, which according to experts, automatic charging is considered the most effective type of charging because after the battery is fully charged, the charger will stop, which will be very useful for the health of the battery. In the following, we mentioned ten safety points that we must keep in mind while working with the car battery charger to prevent accidents such as fire.
