Surely, one of the readers of this article faced such a situation when you urgently need to go somewhere, literally for 5 minutes, but when you approach the car, you understand that the headlights were on all night and the battery charge may not be enough for the trip. To prevent this? charge the battery more often.
It is necessary
- - automatic charger
- - electrolyte
Instructions
Step 1
Of course, this is an annoying case, and someone has already fallen into this trap of a discharged battery.
When charging a car battery, it should be borne in mind that, most likely, we will need an electrolyte, because it tends to evaporate. You can buy electrolyte at any car dealership. Sometimes they are sold even in stores of household appliances and equipment. The electrolyte is a 50% sulfuric acid solution.
Before charging the battery, it does not hurt to check the electrolyte level, if necessary, top up to the desired mark. Also, do not forget to unscrew all the plugs from the battery cover, because evaporation will occur during charging.
Pay attention to the current that you put when charging. It should be set to a value equal to 1/10 of your battery capacity. For example, you have a 50 amp / hour battery, therefore, you need to set the value on the ammeter to 5 units.
Step 2
This is the principle of charging a car battery. Set the value and put it on charge. As soon as you notice that the needle of the ammeter goes to the left side, closer to zero, it means that charging is under way and is being performed correctly. The decrease in the needle of the ammeter to zero is caused by the increasing resistance in the battery itself due to charging.
