Every car enthusiast should have a car battery charger in their arsenal. Operation of the vehicle without this device can become much more difficult. The most useful car charger can be in the winter season, when the battery has to be charged much more often. When the battery is completely discharged, you will have to “light up” the car, which is not always convenient, and in some cases may require additional expenses due to contacting the service station. It is much easier to charge the battery at home. One of the most popular brands of car chargers is Kedr - devices of this brand are bought by many vehicle owners.

Model range of chargers: "Kedr-M"

Charging "Kedr-Auto" is intended for recharging car batteries. Such equipment is mainly used to restore the performance of batteries that have lost it due to sulfation and oxidation reactions of the electrodes. Besides,You can also increase the service life with the help of the Kedr-Auto Mini charger by training the charge-discharge cycle.

Device Features

• Automatically stop battery charging.
• Cyclic charge-discharge operation, the action of which is aimed at restoring the battery capacity as a result of the plate sulfation reaction.
• System of protection against short circuits and incorrectly connected clamps.
• Provided recharging mode that allows you to gain full battery capacity.

Preparation for work

On the back of the charger is a special compartment that hides cords with clips and a network cable.

Voltage charger "Kedr-Avto 4A" can harm human he alth or cause death. The device must be turned off before starting restoration and repair work and changing the fuse. It is strictly forbidden to install homemade fuses and block the ventilation openings of the case. In addition, do not charge the battery near heaters.

Before starting work, cords with terminals are removed from the rear compartment of the device. The first lever of the device is switched to the charge mode, the second - to the cyclic or continuous mode.

How to use Kedr-Auto 4A?

Continuous mode is used when the battery needs to be fully charged.

Cyclic mode is applied whenshaping or desulfation of electrodes. In this mode, a light bulb with a power of 6 watts at 12 volts is connected to the terminals.

Then, the terminals are connected to the current leads with polarity.

Charger "Kedr" has a protection mode against incorrect connection and short circuits. The instructions for the Kedr-Auto 4A charger indicate that its operation is possible only if a battery with a minimum voltage of 10 volts is connected to the terminals. If you try to restore the charge of a completely discharged battery, the device will turn on the protective mode of operation.

Switching between operating modes can be carried out without disconnecting the charger from the mains. According to reviews on Kedr-Auto, the current strength at the beginning of the charging process is 4 A, followed by a gradual decrease. The charger automatically turns off after the battery is fully charged, which is indicated by a special LED. After that, you can transfer the charger to the recharge mode.

Charging the battery in a cyclic mode lasts 45 seconds, after which a special light bulb turns on. This mode does not have automatic shutdown, so it is desirable to control the entire process.

"Kedr-Auto 4A" and "Kedr-Auto 12V"

Both models are used for battery recovery, charging and charge-discharge training cycles.

On the rear wall of the devices are the wires for power and connection to the battery. Dedicated storage compartmentThere are no wires in these models. The instructions for the chargers "Kedr-Auto 4A" and "Kedr-Auto 12V" describe in detail the rules of operation and the procedure for use.

Charger "Kedr-Auto 12V" has the following specifications:

• The rating of rechargeable batteries charged using the device is 12 V.
• Power supply - 220 V.
• The maximum power consumption is 85 A.
• Current - up to 4 A.

Charger "Kedr-Auto 10"

This model is an improved version of the previous memory - Kedr-Auto 4A, which was created in 2008. The device is used to charge a 12 volt battery.

Distinctive features of "Kedr-Auto 10"

• Improved protection against short circuits, overloads and incorrect terminal connections.
• Using only high-quality and modern components.
• Prestart mode, in which the battery is charged with a current of 10 amperes. After that, the charger automatically switches to the battery charging mode with a current of 4 amperes.
• The main stage of charging is replaced by a recharging mode with a current of 0.5 amperes. This mode allows you to avoid overcharging and restore the full charge of the battery.
• Battery desulfation can be done in a cycle.
• The rated current in automatic charging mode is 4A.
• Lightweight charger - only 600 grams.
• Warranty frommanufacturer - 1 year.
• If you follow the instructions for the Kedr-Auto 4A and Kedr-Auto 10 chargers, the service life is 5 years.

Main characteristics of "Kedr-Auto 10"

• Relatively small dimensions - 185 x 130 x 90 millimeters.
• Prestart mode, the current strength of which is 10 amperes.
• Rated current - 4 amps.
• The power consumption of the device is 250 watts.
• The charger allows you to charge batteries with a maximum rating of 12 volts.
• The charger operates from a standard 220 V network.

The battery charging time varies depending on its capacity and degree of discharge. The microprocessor built into the memory controls charging and pre-start mode. The inclusion of all modes and the activation of the device are carried out after the device is switched to automatic mode. First, an increased charge current is applied, after which its strength is reduced to the nominal, which can significantly speed up the process of charging the battery.

Kedr-Avto 4A operation process

The instructions for the Kedr-Auto 4A charger describe in detail the process of using the device and charging the battery. It is impossible to disable the charger, since the protection system protects it from damage even if the terminals were initially connected incorrectly.

Auto mode

Restoring a full battery charge is as follows:

• Connect with polaritycharger terminals.
• The "Automatic" charging mode is activated.
• The plug is connected to the 220 V network.
• The charging process will be interrupted by the device automatically after reaching the maximum charge level, which will be notified by flashing the indicator.

Cyclic mode

In a cycle, the battery is charged to full capacity as follows:

• A car bulb with a nominal value of 12 volts is connected to the battery terminals. It is advisable to select a light bulb whose power is 6 watts.
• The terminals are connected with polarity.
• The corresponding button starts the "Cycle" mode. In this mode, the charge indicator is constantly on.
• The charger is connected to the mains. This mode does not imply automatic shutdown, respectively, the discharge and charge cycle can be repeated indefinitely. For this reason, the user must independently monitor the battery charge.

Before the direct process of charging the battery, plugs are unscrewed from the cans. The terminals after charging or recovery are disconnected only after the charger is disconnected from the 220 V network.

ZU "Kedr": user reviews

Most of the reviews left on Kedr chargers are positive. The most popular model of the device is Kedr-Auto 4A. Somewhat less often you can find reviews on the Kedr-Auto 10 model.

Among the benefits of memorymotorists attribute simplicity and ease of operation, low price to Kedr-Auto (about 1500-2500 rubles) and a long service life. Users often note that the charger can last ten or more years without any complaints. For many users, one of the main benefits is cycling, as it allows for desulfation and revitalization of old batteries. Motorists often note that with the help of this mode it was possible to restore the performance of the batteries, which for a long time were completely discharged. Of course, it is impossible to completely restore the battery capacity, but a positive effect can be achieved.

However, you may encounter negative reviews. Some owners of Kedr-Auto chargers note that the battery does not charge in automatic mode. If the battery capacity exceeds 60 Ah, then it takes a very long time to charge it due to the 4 amp limit. The same rechargeable batteries, the capacity of which exceeds 70 Ah, are not fully charged. Users also noted that Kedr-Auto chargers do not charge those batteries whose charge dropped below 10 volts.

Despite all the negative reviews and shortcomings, Kedr-Auto chargers are one of the best and most popular in the automotive market. The devices allow you to quickly charge batteries, are distinguished by a long service life and wide functionality, and are significantly ahead of their competitors.stamps.
