Which charger-launcher to choose

Every motorist meets with such a problem as a discharged battery. The most common cause is winter cold: low temperature negatively affects the work of the electrochemical device. During the city traffic cycle, the generator does not have the capacity to replenish the battery capacity to the required level. Yes, and non-switched off light devices lead to the discharge of the battery. It is for such cases that a charging and starting device is created, capable not only of charging the battery, but also ensuring the start-up of the engine of the machine. Many motorists have already tried and appreciated the functionality and indispensability of this device.

There are several parameters that you need to rely on when choosing a charger for the car:

• Output voltage (different for batteries for trucks and cars);
• Starting current (the starter's operation depends on its magnitude at start-up);
• Charging current (here it is necessary to focus on battery capacity, alkaline batteries have four times less capacity, and acid ones - ten).

By type and purpose, the devices are divided into combined, household and professional devices. The simplest is the household charger-starting device. Its components are a powerful transformer, an output voltage regulator, a diode bridge and a conventional ammeter. Despite its simplicity, this device has a lot of shortcomings, the most important of which is the lack of protection against typical human errors. Confusion in connecting the poles of the battery will lead to the closure and breakdown of the device. The optimal mode of charging the battery also leaves much to be desired.

Reliable professional starting charger is equipped with protection against short circuits and improper connection of poles, it is possible to automatically adjust the charging current, use reverse charging and voltage stabilization system. Such equipment is necessarily equipped with special clamps, by means of which it is connected to the battery terminals. The qualitative charging-starting device is multifunctional, has many advantages in the design, it has high power and the ability to recharge several batteries at once. It can only be broken if it is misused, for example, it can be connected to the battery using a bare wire, rather than a clip.

The most difficult to operate is a combined charging and starting device. This device is an advanced welding machine equipped with a voltage divider. The maximum voltage of the device in the welding mode can reach 50 - 70V, and the battery needed to replenish it is 12V or 24V, so you should not forget to switch the toggle switch to the charging or starting mode of the engine. If this is not done, the device will easily disable the electronics and wiring the car.

When choosing a charging and starting device, it is necessary to take into account the way of charging the battery. If the current is constant, it is faster, but the battery life is shortened. And if recharging occurs at a constant voltage, the battery is quickly discharged. The best option will be devices that, during charging, first stabilize the current, then - the voltage, and the battery of your car will last longer.
