Why you need to charge the car battery

Charging the car battery is not only important, but also useful. Like most other devices, the battery can lose its properties, namely, lose charge. This is determined not only by its decommissioning and long service life, but also by the negligence of the drivers themselves. It often happens that they forgot to turn off the headlights or close the door to the end; Negative temperatures also affect the quality of the charge.

The car battery must be charged properly. First, the room in which this work will take place should be well ventilated. The fact is that during charging, an explosive mixture of hydrogen and oxygen is released. Secondly, it is necessary to check the electrolyte, its level should reach a certain mark on the battery itself. If there is none, then unscrew the covers and see how much the plates are covered. The liquid should rise above them by 10-15 cm. The serviced battery also requires opening the fillings by unscrewing the covers, but do not remove them. They must be on top of the hole, so that acid does not spill out, but the gases freely flow out. The next step will be cleaning the ventilation holes. It is also worth noting that the car battery should be charged at the cleaned surface of the device. These are the main conditions.

For this process use a battery charger for auto. There are two types of such devices - automatic and manual. The first is a charger for a car battery, which itself watches and controls the current, and also produces an automatic shutdown. A manual device requires special attention, since it needs constant monitoring. Both of them can realize either direct current or voltage at the output. In both ways, the car battery is fully charged. All charging devices operate from a 220 V network.

Now we will consider in detail charge at constant current and at constant voltage. If a lead-antimony battery is charged, the power should not exceed one-tenth the capacity of the device itself. If a battery with calcium and silver alloying is used, an increased initial power of the current is allowed, but in subsequent stages the current must be reduced.

Also, there are memory devices that can not set the required level of current supply. In this case, use a lower value, but at the same time increase the time of charging itself. This method is even more useful for a battery.

A constant voltage for charging is most often used for sealed batteries that are not fully serviced. Voltage does not change during the entire charging time, and the current decreases due to the appearance of resistance inside the battery itself.

With any method of charging, you should always carefully monitor the process.
