How to charge a car battery: an important question

There are many questions as to how much to charge the car battery. This article will provide a minimum of information about this - a small guide to action. Immediately say that the battery can fully charge for 10-12 hours. Let's talk a little more about this, because charging is an important point, and on the correctness of its conduct will depend on the life of your battery.

For example, we have a battery with a capacity of 55 A / h. There are rules that require charging such a device with an electric current, not more than 5.5 A. A single charging process takes approximately 10 hours. It is understandable that the more current there is, the less time will take to charge, and vice versa: the less current, the more time it will take.

If the question of how much to charge the battery, more or less clear, let's talk about recharging. Immediately need to say that this is a short transfer of power to the battery, which is discharged. Let us give an example for persuasiveness. To start the engine, the battery does not have enough power. You connect it to another car-donor. So, when the "donor" engine is running at a medium speed (30 A is given at the same time), your battery will take 0.5 A of charge every minute. This figure can easily be calculated using the formula 1/60 * 30 = 0.5 A / hour. We consider further. The starting current is approximately 200 A. So charging a battery lasting one minute, can torment your starter for about 9 seconds, but the engine will not start at the same time.

How much should I charge the car battery so that it can start the engine? It's enough 10-15 minutes. You can and a little more. However, after this, you will have to ride around the nearest streets to fully charge the battery. During such a "walk" it is desirable to turn off all unnecessary consumers of current: radio, lights, stove and other appliances.

As for car-care centers, there are often times when the master connects the battery to the charger for only 15 minutes, and then returns the device to the owner, informing him of the successful charging. However, we already know how much to charge the battery, so this time to charge the battery can not suffice.

To sufficiently charge the battery, you need to spend 10-12 hours. The current density must not be more than 0.1 battery capacity. About how much to charge the battery, you learn by boiling, they are accompanied by the end of charging. According to the hydrometer, the full charge of the battery in winter amounts to 1.27-1.28, and in the summer it is 1.26.

The process of charging the battery is not fast. But I have to spend a little time. Otherwise, in the future, you will have to buy a new battery due to the failure of the old battery. How much time to charge a car battery depends on the type of device, as well as on the amount of current. But still, if you want to charge correctly, thus increasing the life of the device, please contact a qualified specialist.
