8 rules: how to choose a car charger

Battery charger for car battery-important equipment, which should be in every motorist. If any car owner can not be afraid that the battery is suddenly fails, you can always be it pretty quickly restore its performance. After all, no one can accurately predict when the battery is discharged, since it affects a lot of factors. For example, the battery may lose discharge due to prolonged use, the sharp reduction in air temperature outdoors, left overnight included dimensions, etc. And restore the dissipated charge is always possible with a special charger.

8 rules: how to choose a car charger

The principle of all modern zaryadok quite simple. The battery with terminals connected to the battery charger, which in turn is connected to the mains. Memory problem consists in converting from AC to DC outlet and decreasing the voltage to the required level, which is used to charge the automobile batteries.

In response to the question: "What is the charger to buy cars,"-keep in mind that different types of batteries can be used on different machines: lead-acid, gel, hybrid, serviced or unattended. Already on the basis of this, it is necessary to choose a model charger, usually in the instructions to the instrument manufacturer necessarily indicate for what types of battery fits this unit. To help you, there are some rules that will help you if you do not know how to choose a car charger.

Rule №1. Look at the level of the charging voltage

The output voltage-an important parameter for any charger. Since working memory comes with different types of batteries, and the operating voltage for their recovery may require different. For example, most of the battery installed in passenger cars, have an operating voltage of 12V. For them, the optimum charging voltage is 14.4 V. The indicator is slightly higher, as is required to take it with a small margin. But there are also buses, trucks, special vehicles battery, which often have an operating voltage of 24 V. and motorcycle batteries, which are often operating voltage is equal to 6.

So, before buying a battery charger, this parameter must take into account mandatory. You must determine which batteries will be used by the device and therefore for them to choose the best indicator of the charging voltage. Best of all, if the device will be able to switch the voltage and adjust it, while its scope will be wider, and one device can be recharged different types of batteries.

Rule number 2. Be aware of your capacity avtoakkumulyatora

From capacity rechargeable power source is directly dependent requirements indicator of the maximum charging current. Typically, the recommended is a value equal to 10 percent of battery capacity. That is, for example, if you are going to restore the battery capacity of 100 Ah, the current must not exceed 10 A. Moreover, should take into account that at this current a full recovery will take between 10 to 12 hours. If you want to speed up the charging, the current can be increased, however, it may adversely affect the working power supply capacities. Excessive use of charging at high currents is not necessary, it is possible to significantly reduce the battery life. Learn your battery capacity is quite simple, the manufacturer always indicate this option on the product.

In addition, the manufacturer of automobile chargers often indicate in the instructions for your devices battery capacity that this machine is capable of charge.

Also, when choosing a memory worth paying attention to the possibility of stepwise or stepless adjustment of the charging current and the function limiting the maximum value.

Rule № 3. Determine the type charger for automobile accumulators

There are two main types of chargers:. Transformer and pulse

Transformer-have been known for a very long time, these devices have more than a hundred years, we can say that they came together with the first battery. Within these devices are already clear from the name, it is a transformer and rectifier. They still work properly and cope well with its task. But there are also some disadvantages: heavy, impressive dimensions. Devices of this type carried out the charge of the battery at a constant current, it allows you to maximize the battery to recover.

These in turn are divided into automatic and non-automatic. The latter are more difficult to use because they need constant participation in the process of an experienced operator, who must monitor the performance of the device. Automatic also extremely simple to operate, since the control is conducted on the side of the charging device which is equipped with an ammeter and a voltmeter. Upon reaching full charge the device automatically turns off and strictly control by the operator would be required.

Inverter-this is a more modern equipment, the construction of which has significantly reduce the size of the device. This compact charger you can always carry with them in the trunk. They operate at higher frequencies, within them there is a compact voltage converter, which ensures efficient operation. And thanks to the embedded microprocessor, which is responsible for monitoring all the main operating parameters, charging occurs in a fully automatic mode. After reaching full charge is stopped and the device enters the standby mode. Some models have a storage function, that is, the device can be a long time be left connected to the battery, and with a decrease in the charge level is automatically included to maintain the battery in working condition.

Rule number 4. It is worth desulfation function

The trouble many lead-acid batteries is that the plates inside the lead sulfate produced during their discharge. This is a pretty solid crystal plaque, no electric current is passed. This leads to the fact that the plates do not have proper contact with the electrolyte, and therefore the battery can not be fully charged, it begins to lose capacity and decreases its efficiency. It can even lead to complete failure of the battery system, then you have to buy a new avtoakkumulyator.

In order to break the layer of sulfate crystals developed a special desulfation mode. Its essence lies in the supply to the battery of short current pulses that destroy the plaque, resulting in the battery is reduced, as the plates are cleaned. If the car charger has a similar option, for just a few cycles, it will be possible to fully restore deeply discharged battery sulfation and subject.

Rule number 5. To simplify your task, choose automatic chargers

We've already talked a little bit about what memories are automatic, ie operate with little or no human intervention. It is very convenient and greatly simplifies life. The microprocessor is able to completely replace the operator, as the control over the entire process. And then everything will be as accurate as possible, and the probability of failure is very low, while the man can always make a mistake due to carelessness or inexperience. In addition, automatic impulse devices, usually have a whole range of protection systems that prevent overheating, over-voltage or short circuit. That is, you can not be afraid to damage the battery.

Another benefit of automation is the ability to choose between several modes. Only here we must bear in mind that a specific number of modes in different models of different, and it should look before buying, to suit your needs.

Rule number 6. Pay attention to the presence of the temperature compensation function

Every driver should know that you can not charge the battery, which had just been brought to the frosty streets. It is necessary to wait until the battery warms up to room temperature, and it takes too much time. What do you do if time is short and I want to put the battery on charge immediately?

In some models of modern chargers has a special mode allowing the battery charge without the need for heating. It is very convenient. The principle here is very simple-a cold charge the battery starts a small current, then the current level gradually increases. As a result, charging goes into power saving mode, and there is no fear that the battery is subjected to destruction.

Rule number 7. Pay attention to the presence of the display

If the unit is equipped with an LCD display, it greatly simplifies the control over its work. As a rule, the display shows all the modes and stages of charging the battery, and you can always quickly get information on what stage the process. The screen also displays information on the current use force, operating voltage, battery status, and more. It is very convenient if there is light, then in the evening everything will be clearly visible.

Rule number 8. Choose only high-quality equipment with due protection level

When choosing a charger for the battery be sure to look for the presence of required security functions. This includes such features:

  • protection against reverse polarity, which will not include memory from improper connections to the battery terminals when confused.
  • Protection of recharge required option to automatically turn off the charger to prevent the negative impact on the battery.
  • overload protection
  • short-circuit protection and surge on the network.

If the device has all these options, you can be sure of the long term of its operation, safe and efficient operation.
