EdupradaYour car’s battery helps power the entire electrical and starting system. If you feel that it is showing signs of weakening or that it is broken, you can recharge it. A battery is recharged automatically while driving, or using a specific charger.
How to recharge a car battery?
The battery of your car allows it to start passing through the starter and also supplies all the electrical or electronic elements. Your car battery also powers other functions of your vehicle:
- Raising and lowering the electric windows;
- Activation of the windshield wipers;
- The horn;
- Turning on and maintaining the radio;
- Locking the doors;
- Switching on all vehicle headlights.
Your battery is made up of two electrodes + and – which are bathed in electrolyte (sulfuric acid). The current is delivered into the battery with the connection of the + and – terminals where the electrons move from – to +
The recharging of your battery takes place when the alternator is connected because the electrons move in the opposite direction , from + to -. This reaction allows the liquid to recharge with electrons. The battery therefore does not recharge itself when your engine is off. It also loses its energy in the event of a long period of non-use of a vehicle.
How long does it take to recharge a car battery?
The time required to recharge a car battery depends on several factors, such as the discharge status of the battery, the capacity of the battery , the charging current of the charger used and other variables. In general, here are some rough estimates:
- Charging while driving: When you drive your car, the alternator generally recharges the battery. Fully recharging the battery while driving can take on average around 20 minutes. However, this may vary depending on driving time, speed, driving conditions and battery condition;
- Charging with a battery charger: The charging time with a battery charger depends on the charging current provided by the charger and the capacity of the battery. As a general rule, for a discharged battery, it takes several hours to recharge. Common battery chargers can take 6 to 12 hours to fully charge a car battery. However, faster chargers can reduce this charging time.
It is important to follow the charger and battery manufacturer’s recommendations for more accurate charging time information specific to your situation. In addition, it is essential to follow safety instructions when recharging the battery to avoid any potential risks.
