Line of chargers for car batteries

Regardless of the time of year, whether it's summer or winter, buying a battery charger is always relevant for a motorist. To extend the service life of the battery, you should correctly approach the choice of a charger, because its type and principle of operation will depend on the convenience of operation and the quality of the charge.

All chargers differ in power and maximum charge current. In this case, the choice should be guided by the principle that the larger the capacity of your battery– the more powerful the charger should be purchased, because a less powerful device will spend too much time recharging an energy-intensive battery. It is recommended to choose a charger with a maximum charge current of at least 10% of the capacity of your battery.
And remember, the power reserve is never superfluous! The most widespread are two types of chargers that differ in the principle of operation – transformer and pulse.

TRANSFORMER CHARGERS

Transformer chargers work on the principle of a conventional transformer, which we remember from school physics lessons.

It looks like an ordinary magnetic rod, a wire is laid on it in dense layers – this is a winding.
The quality and output parameters of such a device depend on the number of turns of the winding and the material of the wires.
The main function of transformer chargers is to convert alternating current from the household power grid into direct current and transfer it to the battery for recharging.
As a rule, such chargers have no automation, and the adjustment of the operation parameters is carried out manually or not at all. As a result, the density and quality of the charge are low, or in the case of manual adjustment, you will have to constantly monitor the operation process.

ADVANTAGES OF transformer chargers:

Low cost of the product due to the simplicity of the design;
Ease of operation;
Breakdowns are extremely rare;
Inexpensive repair in case of breakdown.

DISADVANTAGES OF transformer chargers:

A heavy and bulky device that is not always convenient to store and transport;
Preliminary measurement of the charge level is required;
Constant monitoring of the operation process, since excess of the charge current (10% of the capacity) will lead to boiling of the electrolyte, increased wear of the battery and excessive release of harmful substances;
Ideally, the charging current will have to be measured every 30-40 minutes so as not to miss the moment when everything can still be fixed.

PULSE CHARGERS

Pulse chargers are a more modern option that affect the battery with a high-frequency current, which leads to the supply of charge in small pulses. The whole charging process is divided into several stages. First comes the traditional direct current charging. Further, upon reaching a certain value, the device automatically switches to alternating current mode, gradually reducing its value to zero and stabilizing the voltage. The advantage of this algorithm is that boiling of the electrolyte and evaporation of harmful gases are excluded. Pulse chargers are also capable of charging batteries not only of passenger cars, but also trucks, motorcycles, boats and boats. The design of the devices includes: a pulse transformer, a diode rectifier, a stabilization unit, an electronic module for process control and various display systems, which makes pulse chargers more compact and lighter compared to transformer chargers. Dimensions and weight are not the main advantage of pulse chargers.

ADVANTAGES OF Pulse chargers:

Automatic charging process. The microprocessor of the device independently tests and evaluates the condition and capacity of the battery, monitors the charge level and sets the optimal operating mode;
Informative indication that will timely show incorrect connection of the terminals, battery malfunction, incorrect mode and much more;
Effective protection system. The microprocessor constantly monitors the state of the battery from the moment it is connected, during operation and until the terminals are completely disconnected, preventing its damage, overheating, short circuit, overcharging, etc.;
A separate advantage of pulse chargers is the recovery mode (desulfatation), which allows not only to restore capacity, but also significantly extend the service life of batteries and postpone the purchase of a new one. This mode is also recommended as a preventive measure.

DISADVANTAGES OF pulse chargers:

The price is noticeably higher than transformer devices;
The device is often not maintainable or the cost of repair is quite high.

NEW ITEMS!

The new line of TM KOLNER chargers has a number of advantages:

VERSATILITY - Kolner pulse chargers are designed for recharging batteries of various types:

lead-acid (WET, SLA, EFB, MF, SMF, AGM);
calcium (CA);
lithium (LIB);
helium (GEL).

Despite their small size and light weight (0.4 - 1.1 kg), the chargers are capable of charging batteries with a capacity of up to 200 Ah, which are used in trucks, tractors and other heavy equipment.

A 7-STEP INTELLIGENT CHARGING PROGRAM allows you to smoothly restore the battery and achieve a dense charge.

The central microprocessor automatically detects the battery voltage of 12 V or 24 V, tests it and sets the necessary algorithm for the subsequent charging process.

SUMMER AND WINTER MODES OF OPERATION - The automation of the device adjusts the charge parameters depending on the ambient temperature for a gentle recovery and obtaining a deeper charge of the battery.

EASE OF USE - To get started, you need to connect the charger to the battery and select the appropriate type of charge. At the end of operation, the charger will switch to standby mode and display the result of operation.

FULL PROTECTION - The charger is equipped with protection against overload, overheating, short circuit, incorrect polarity of cable connections and overcharging of the battery.

TOUCH CONTROL AND INDICATION - The touch button on the front panel is used to select the operating mode, and the current state and charging process are displayed on the display.

So, let's summarize

If you do not take into account the cost of pulse chargers, they significantly outperform transformer chargers in most parameters. But, despite this, transformer chargers still show themselves well, and quite often it will be appropriate to save money and use an old proven product. If an unattended battery is used, a pulse charger should be purchased to avoid damage to the electrodes.
