Every motorist encountered such a problem, as the discharged battery.The most common cause are the winter cold: low temperature adversely affects the operation of the electrochemical device.During urban driving cycle, the generator is not able to recharge the battery capacity to the required level.And powershift light devices lead to battery discharge.For such cases created Charger-starting device capable not only to charge the battery, but also to ensure engine start the car.Many motorists have tried and evaluated the functionality and the indispensability of this device.
There are several parameters that need to be supported by selecting Charging-starting devices for the car:
- output voltage (different from the batteries for trucks and passenger cars);
- inrush current (on its magnitude depends on the work the starter when starting);
- charging current (here should focus on the capacity of the battery, alkaline batteries have it four times less capacitance from acid - ten).
by type and destination devices are divided into combined, household and professional appliances.The simplest is a domestic charge-starting device.Its components - a powerful transformer, the regulator output voltage, 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 from the typical human errors.Confusion connecting poles of the battery and lead to closure of the malfunction.Optimum battery charging mode also leaves much to be desired.
reliable professional starter battery charger is equipped with protection against short circuit and reverse polarity, it is possible to automatically adjust the charging current, the use of reverse charge and voltage stabilization systems.Such equipment is necessarily equipped with special clamps, with which it is connected to the battery terminals.Quality Charger-starting device is multifunctional, has a lot of advantages in the design, features high capacity and the ability to charge multiple batteries.Break it can only be in the event of improper use, for example, to connect to the battery using the bare wires, not the clip.
most complex operation is the combined charge-starting device.This device is an improved welding apparatus equipped with the voltage divider.Maximum voltage unit in welding can reach 50 - 70V, and needed to recharge the battery - 12V or 24V, so you can not forget to switch the switch to charging mode or start the engine.If you do not, the device simply will damage the electronics and wiring of the car.
When selecting Charger-starting devices, it is necessary to take into account the method of charging the battery.If the current is constant, it is faster, but decreases battery life.If charging takes place at a constant voltage, the battery runs out quickly.The best option would be a device that during the charging current is first stabilized and then - the voltage and the battery of your car will last longer.
