Probably, every motorist faced withthe problem of a discharged battery. Especially it is unpleasant, when everything is found 5 minutes before departure. There are two ways out of this situation. The first is the installation of a new, pre-charged battery on the car. The second is the recharging of the old battery with a special device. Of course, the first method will very quickly solve the situation, but few of us store 2 charged batteries in the garage. Therefore, the only way out of the situation will be the use of such devices as start-up devices for cars. We'll talk about them today.
Voltage
All start-up devices can be 12-,and 24-volt ones. The first type is recommended for cars, minivans and minibuses. As for 24-volt devices, such start-up devices for trucks and large buses are used. There are also 6-volt devices. Typically, such tools charge only motorcycle batteries.
What is this device?
Start-up devices for cars areare small boxes made of strong plastic, which have special ventilation holes and connectors for the terminals. On the front side of this mechanism there is an on indicator, as well as a regulator of the magnitude of the charging current. In addition, each device is equipped with an ammeter scale, which allows you to determine the current level of the battery. Inside, the start-up devices for cars have a circuit and a special fuse, which protects the device from improper connection and further failure.
At the moment, there are 2 types of these devices:
The first type includes a specialtransformer and diode bridge. Despite the plus in the price category, many drivers often abuse such devices. Indeed, household start-up devices for cars are highly vulnerable to short circuits. If you incorrectly connect it (mix up plus with a minus), in the next few seconds such device will simply burn down, and already anything you will not save it. In addition, the mode of charging the battery they are not very happy.
As for professional devices, theymuch safer and safer to use than domestic. Such devices are equipped with fuses that prevent the risk of a short circuit. Also professional tools have special clamps, thanks to which you can easily fix the device to the battery, which also prevents the failure of ROM. Among the significant advantages drivers note the possibility of adjusting the charging current, as well as a stable supply voltage.
Start-up devices for cars: price
At the moment, the cost of such devices is very high.is diverse. Households are sold at a price of 2-3 thousand rubles, and the cost of professional starts at 7000 and can reach a mark of 26 thousand rubles.
