All secrets of correct battery charging

In this article we learn how to properly charge the car battery with a charger.

Charged and, it is the key to the fact that the car will start without problems in harsh frosts.

The battery itself is unpretentious and if everything in the car is in order, then it will not deliver any hassle, but it is until time.

In the usual working mode, the battery is a source of electricity for mounting networks of auto exactly until the engine started, then it transmits this role to the generator, from which herself itself is recharged, but suddenly something went wrong ...

For example, you for a long time left your iron horse in the garage or forgot to turn off the headlights, when they left home, the result of these situations will be the discharge of the battery, after which you can no longer be able to get on your own.

What to do? In fact, there is a way out. Any car owner for such cases should be the so-called charger in the arsenal.

Before proceeding to recharging the battery, you need to find out several nuances.

First, you need to know exactly what type of battery you have. There are several varieties:

• children with liquid electrolyte (WET) is the most common type of batteries;
• gel (GEL) - belong to the so-called maintenanceable batteries, sealed. The electrolyte in them is in a gel condition;
• AGM batteries - also belong to hermetic, maintenanceable. Their main chip is the porous filler of fiberglass compartments.

As we have already said, the most chassis are still a battery with a liquid electrolyte, so in this article we will consider in detail how to correct the battery of the car of this type.

The remaining two are less popular due to their high cost, but gradually gain momentum in the auto industry and are increasingly found under the hoods of machines. In principle, more or less modern chargers already have modes of operation for different types of batteries.

Checking the battery

We return to the problem voiced at the beginning of the article, and before talking about how to properly charge the car battery by the charger, you need to check something.

For example, after a long downtime, the machine will not start. Perhaps it was in the battery - he was discharged, and to make sure that it is necessary to climb under the hood and get to the battery, after arm with a voltmeter.

We will check how bad it is. For example, take the most common format - battery, voltage 12.6+ volts. So much should be on terminals of a fully charged battery.

Voltage 12.00 Volt indicates that it is tempered by half (50%), 11.75 volts - 30% of the charge, and all that below 10.5 volts speaks of full discharge.

There is another way to check, however, it is suitable only for serviced types of lead-acid acb.

We will explore the density of the electrolyte using a special device - a meterometer.

If you do not have, not trouble, you can buy it almost in any auto parts store. Perhair the battery in all banks, and verify the results with the sign.

How to charge the car battery charger

So, friends, all checks are made and we made sure that the battery in the car is really discharged. This fact, of course, does not please, but it is impossible to despair, everything can be corrected. It's time to talk, how to charge the car battery.

The first without which this procedure is not possible - the charger (memory). If you do not have, then it's urgently run to the store. The self-respecting motorist must have such a device.

The memory of the memory There is a great set, but for our purposes, the battery wet charging will fit almost any, the main thing is to make sure that it is suitable for the voltage level for the battery and is able to issue the necessary currents. It should be noted that it is possible to meet not only charging, but also commissioning, as well as starting devices, which not only replenish battery reserves, but also can start the engine, instead of the battery.

Suppose I have been purchased, the hood of the machine is open. It's time to learn how to properly charge the car battery with a charger.

There are certain rules, they will help not only make everything right from the technical side, but also not harm the health of others around them.

What is meant? If you are removing the battery, then no way to carry out any procedures at home. In the process of charging the battery with an electrolyte, harmful and combustible substances are distinguished, the electrolyte is a solution of sulfuric acid, and when handling it needs to be remembered about the means of individual protection.

Now about how to charge the car battery by the charger. For this, by the way, it is not necessary to remove the acb, although it is still more convenient to produce all the procedures in the garage or in any other suitable room.

When charging, without removing the battery from the machine, you should disconnect the minus terminal.

And so, all the points:

• clean the battery from dirt, especially contacts;
• unscrew the caps of the cans - first, it is necessary to check the level of the electrolyte, which, if necessary, will have to add, and, secondly, in charge, it will be secured from increasing pressure inside;
• connect the memory according to the polarity of the contacts;
• it is very important to correctly set the charging current - it should be no more than 10% of the capacity of the battery. For example, if your battery has a capacity of 60 a / h, the charging current must be no more than 6 amps, and in general, the less, the better for the battery is about 2-3 amps. It is important to note that at rated current, the process of charge stretches from 4 to 10 hours;
• when the charging current reaches the value of 200 mA, the memory can be turned off, although modern devices will make it automatically;
• at the end again, check the electrolyte density in banks;
• if everything is in order, put the battery in the car and you can go.

"Great!", "You say," But what to do if you wait 10 hours? " In fact, there is a way out, however, but to use it only in extreme cases and infrequently.

Let's open a small secret how to charge the battery as fast as possible. It is necessary to increase the current by 30%, but no more. For example, if you set a current of 6 amps in normal mode, then with an accelerated you need to set 8.

This trick allows the battery for about 20-30 minutes to scatter energy, which is enough to start the engine. It is better to use this way as much as possible, otherwise the battery is rapidly degrading and fails.

When charging the battery, gases are highlighted that can ignite from the spark that leads to an explosion of the battery. Provide good ventilation in the room where the battery is charging and be careful!

Well, colleagues-motorists, expressed almost everything that knew how to properly charge the car battery with a charger. It's time to sum up the final line under the article and remind you that the best way to know your car is to read our blog.
