The battery is the most important node in the power supply system of any car, as a result of which it is necessary to monitor and maintain it in good condition. The main role of the battery is to accumulate electrical energy and transfer it to all the main components and assemblies of the car. Over time, the working plates of the battery undergo sulfation processes, as a result of which the degree of charge of the system decreases. In this regard, before many drivers, the question of how to charge the car’s battery is quite relevant. Proper recharging and timely maintenance of the battery (battery) can significantly extend its service life, as a result of which the reliability of the battery will increase significantly.
Each driver should also be aware that in a cold climate, a low degree of battery charge becomes the main cause of plate oxidation, which, when started, can even lead to a change in the polarity of individual cans. In warm climates, too high a charge of the battery can lead to intense destruction of the gratings of the positive plates, as a result of which the active mass will collapse from them. Therefore, each competent driver should periodically make appropriate measurements, thanks to which he can find out the exact condition of his battery.
So, how to charge the battery, and what methods exist for this? The most common ways to recharge the batteries are as follows:
- Control and training cycle.
- Forced charging.
- Impulse current charging.
- Asymmetric charging.
- Ripple charge.
Of all the above, the control and training cycle is most often used, which allows to achieve high-quality battery charging, with the restoration of efficiency and an increase in its useful life. An important instrument that provides significant assistance in monitoring the battery is an anemometer. With its help, the density of the electrolyte is measured , due to which the accumulation of electric charging inside the device is carried out. In order to charge the battery, you need to have a battery charger for AB, which can be purchased at the car shop. In addition, we will need a load plug (or multimeter), with which it will be possible to measure voltage with and without load. Thus, if until this time you did not know how to charge the battery, now you can already do it.
Previously, it was removed from the car to recharge the battery, but today there are quite big difficulties with this. Thanks to the development of multimedia technology and automation systems, many drivers refuse to remove the battery, because this results in a reset of the radio, climate control, on-board computer, as well as system errors that are recorded in the cache when the engine is running. If you disconnect the battery, this information from the memory will be erased and the service station will no longer be able to make an accurate computer diagnosis of the technical condition of your car. That is why at present the vast majority of car owners prefer to recharge the battery without removing it from the car.
For this, it is necessary to carry out a series of preparatory measures that will help to carry out all the work as safely as possible.
Here's how to charge a car’s battery without removing it:
- If the car was in the cold, then after entering the garage it should stand for several hours, so that its temperature reaches 22-28 degrees Celsius.
- If possible, the ignition, as well as all additional electrical appliances, should be turned off or put into standby (sleep) mode.
- Before recharging, it is necessary to take readings from the battery (electrolyte density, voltage at the terminals).
- Then you should connect the charger to the terminals of the car and apply voltage. It is important to consider that since the battery is on the car, the voltage should be applied gradually (in this case, it is necessary to carefully ensure that there are no power surges). The charging time of a car battery is on average from 3 to 6 hours, which depends on both the battery itself and the type of charger for it. After completion, you should re-take measurements to make sure the success of the operation.
Thus, we now know how to charge the battery, and what precautions should be taken to do this. In conclusion, it should be emphasized that, on average, a good battery lasts up to 10 years, after which it should be replaced.
