How to properly charge the battery: a few tips for the car enthusiast

When the car is often started, when the starter is often used, the car battery has the ability to quickly discharge. In this situation, the motorist has a question: "How to properly charge the battery, so that he served faithfully as long as possible?"

The car battery is charged from the charger. That's just the size of this device is slightly more than usual. It is a voltage transformer, which can be adjusted. The device must be combined with the voltage rectifier. Its task is to provide a constant current, which, in fact, charges the battery. About how to properly charge the car battery, it will go further.

The ideal voltage for a standard lead-acid battery should not exceed the bar at 10% of the battery-specified ampere-hour battery performance. However, if the battery has a capacity of 50 ampere-hours, then the voltage should be 5 amps, and it will be charged for 10 hours. If your battery is gel, sealed, then it needs no more than 2.5% of the ampere-hour characteristic.

How to properly charge the battery? There are several ways to charge. Which is better - it's up to you. But both methods are more or less less efficient and more safe for a car battery.

The first way: charging the battery occurs with a constant increase in the voltage charge. In this case, the degree of charge is directly proportional to the voltage. If it is provided by the charger, does not exceed 14.4V, then within a day the battery of the car will be charged only by 80%. To bring the bar to 90%, the voltage is 15V. The battery will be 100% charged within 24 hours only if the voltage supplied by the charger is not less than 16.4V. This method is laborious and has one significant minus - it requires constant monitoring, since immediately required volts for charging can not be 100% supplied.

Proper charging of the car battery directly depends on the way it is carried out. The second charging method is more efficient and reliable as a battery safety feature. From the charger, a current of 0.1 battery capacity is applied to the terminals of the battery. For example, if the battery has a capacity of 60 amperes / hour, the current supplied should not exceed 6 amperes. In such a situation it is better to use a device that will automatically maintain the voltage or check it with an interval.

About the end of charging the battery will signal the boiling of liquid (electrolyte) in the cans. After that, it is required to reduce the applied current in half. That is, if you served 6 volts, you need to apply 3 volts. When the voltage reaches the 15 volt mark, the charging current is again reduced by a factor of 2. If for several hours the indicators of the charging current and voltage are unchanged - the charging of the battery for your car is completed. So you learned how to properly charge the battery.
