With a frequent car factory, when the starter is often used, the car battery has the ability to quickly discharge. In such a situation, the question arises for the motorist: "How to properly charge the battery so that it lasts faithfully for as long as possible?"
The car battery is being charged by the charger. That's just the size of this device is slightly larger than usual. It is a voltage transformer that can be regulated. The device must be combined with a voltage rectifier. Its task is to provide
direct current, which, in fact, charges the battery. On how to properly charge the car battery, we will go further.
The ideal voltage for a standard lead-acid battery should not exceed the bar of 10% of the ampere-hour characteristic of the battery indicated on the battery. However, if the battery has a capacity of 50 ampere-hours, then the voltage should be 5 amperes, 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 charge the battery? There are several ways to charge. Which is better - you decide. But both methods are more less effective and most safe for a car battery.
The first way:
charging the battery occurs with a constant increase in charge voltage. In this case, the degree of charge is directly dependent on the voltage. If it, issued by the charger, does not exceed 14.4V, then during the day the car’s
battery will be charged only 80%. To bring the bar to 90%, a voltage of 15V is required. A battery charge of 100% during the day will occur only if the voltage supplied by the charger is at least 16.4V. This method is time-consuming and has one significant minus - it requires constant monitoring, since immediately the required volts for charging cannot be 100% charged.
Proper
charging of a car battery directly depends on how it is carried out. The second method of charging is more efficient and reliable as a battery. A current equal to 0.1 of the battery capacity is supplied from the charger to
the battery terminals . For example, if the battery has a capacity of 60 amperes / hour, the supplied current should not exceed 6 amperes. In such a situation, it is better to use a device that will automatically maintain voltage or check it at intervals.
The end of charging the battery will signal the boiling liquid (electrolyte) in banks. Then you need to reduce the supplied current by half. That is, if you applied 6 volts, you need to apply 3 volts. When the voltage reaches the mark of 15 volts, the charging current is again reduced by 2 times. If for several hours the indicators of the charging current and voltage are unchanged - the battery charging for your car is completed. So you found out how to properly charge the battery.
