Are you on this page? So you need to know how to charge the car battery . You got behind the wheel in the morning, tried to start the engine, and in response you heard silence. Familiar situation? Naturally, it became clear that the battery, and therefore you, had problems. Long before the "dead" engine, an indicator on the dashboard indicated this.
First you need to check the battery charge . As a rule, it is precisely his absence that causes the "silence" of your engine. The conclusion is simple: you need to urgently charge the battery.
We start by turning off the battery, first remove the terminal from the “minus”, and then from the “plus”, this is a very important point. Solving the question of how to charge the car’s battery , first we’ll touch on battery diagnostics.
Firstly, it is necessary to check the density of the electrolyte using a hydrometer. First you need to unscrew the protective bolts and provide access to the electrolyte. If the battery is fully charged, then its reading will be at the level of 1.28 - 1.30 g / cm3.
Secondly, it is necessary to check the electrolyte level, it should be about 10-15 mm higher than the plates or on a scale outside the battery between "min" and "max" (on a translucent case). If the level is lower, add distilled water. During the entire charging time, the battery must be open so that the liquid comes into contact with air, this is an important point. When deciding on how to charge the car’s battery, you absolutely do not need to use the product of local craftsmen, a home-made “charger”.
In order to charge the battery, a charger (charger) is required . When connecting, it is necessary to connect the terminals of the charger with the battery according to the marking: “plus” of the charger with “plus” of the battery, “minus” of the charger with “minus” the battery, then connect the third wire to the network.
Depending on the degree of discharge of the battery and its type, it takes different time to charge the battery. On the charger, the arrow of the indicator will show “0” when the battery is fully charged. There are two situations in life, consider them:
- if there is an urgent problem and you need to quickly charge the battery in a short period of time, then at maximum current, without removing the battery from the car, charge it for 20 minutes;
- with a sufficient amount of time, removing the battery, it is necessary to put it on charge for 8-12 hours (usually at night, at home under supervision), the current strength for the charge should be minimal, not more than 5.5 A.
Faced with the question of how to charge the car battery at home, you need to check a few points. If the battery is brought into the room from frost, you need to wait until it warms up to ambient temperature.
Need to worry about technology
If you want to charge the gel battery, then it is better to do this with a special charger for gel batteries (due to their specifics), it uses very small charging currents.
Here are brief answers on how to charge your car’s battery, which will help you “reanimate” your vehicle.
