There are many questions about how much to charge a car battery. This article will provide a minimum of information on this subject - a small guide to action. Let's say right away that the battery will be able to fully charge for 10-12 hours. Let's talk a little more about this, because charging is an important moment, and the life of your battery will depend on the correctness of its implementation.
For example, we have a battery with a capacity of 55 Ah. There are rules that require charging such a device with a current of no more than 5.5 A. The whole charging process takes about 10 hours. It is quite clear that the greater the current, the less time it will take to charge, and vice versa: the lower the current, the more time will be needed.
If the question of how much to charge the battery is more or less clear, let'sLet's talk about recharging. It must be said right away that this is a short transfer of charge to a battery that has run out. Let's give an example for persuasiveness. The battery does not have enough power to start the engine. You connect it to another "donor" car. So, when the “donor” engine is running at medium speed (a charge of 30 A is issued at the same time), your battery will take 0.5 A of charge every minute. This figure is easy to calculate using the formula 1/6030 \u003d 0.5 A / hour. We count further. The cranking current is approximately 200A. So charging the battery for one minute can torture your starter for about 9 seconds, but the engine will not be able to start.
How long does it take to charge a car battery to start the engine? 10-15 minutes is enough. Maybe a little more. However, after that you will have to travel around the nearest streets to fully charge the battery. During such a “walk”, it is advisable to turn off all unnecessary current consumers: radio, headlights, stove and other appliances.
As for car services, there are often moments when the master connects the battery to the charger for only 15 minutes, and then returns the device to the owner, reporting successful charging. However, we already know how long to charge the battery, so there may not be enough time to charge the battery.
To sufficiently charge the battery,need to spend 10-12 hours. The current density should be no more than 0.1 of the battery capacity. You will learn how much to charge the battery by boiling, it is accompanied by the end of charging. According to the hydrometer, the total battery charge in winter is - 1.27-1.28, and in summer - 1.26.
The process of charging the battery is not fast. But it will take some time. Otherwise, in the future you will have to buy a new battery due to the failure of the old one. How long it takes 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 it correctly, thereby increasing the life of the device, contact qualified specialists.

The main parts of the vehicle should include the battery. During normal operation, this battery is charged while the vehicle is running. But there are often cases when, if other devices in the car malfunction, it must be charged using a special device. Such operating conditions affect the rapid wear of the device. In addition, from time to time it needs to be refueled. Many people often get confused about what to add to the battery: water or electrolyte
