How to choose a car battery charger? There are many models on the market, and making the right choice is quite difficult. First of all, it is important to note that the devices differ greatly in parameters. There are also design features. However, general recommendations can be given.
How to choose a device?
The output voltage parameter cannot exceed 12 V. If you select a simple model, then the power should be about 40 watts. The overload indicator is on average 12 A. Many modern modifications are sold with high-quality fuses. They have a first-class heat protection system.
It is also important to pay attention to design features. First of all, the clamps on the model are checked. The housing must be sealed. The voltage switch is most commonly used rotary type. Many modifications are made with the function of continuous charging. Also, the light indication of the system is checked before purchase.
How to choose a powerful model? In this case, the output voltage should be 15 V. The overload parameter for good devices is 25 A. The case is made of an impact-resistant type. Modern models have metal clips with latches. In total, the device must have at least two fuses. There is a high-quality charging for batteries in the region of 3800 rubles.
How to make a 6V model?
How to charge a 6V car battery? In this case, a high-quality step-down transformer is required to assemble the device. Resistors are most often selected without lining. Capacitors are used to supply voltage to the transformer. For chargers, operational and pulse modifications are suitable.
In this case, it is more expedient to stop at the first option. Clamps are usually made of steel. Expanders are used to overcome impulse noise. If you assemble a modification with the function of continuous charging, then a tetrode is used. The specified item on the market is sold with or without a stabilizer.
Homemade 10V device
Homemade 10 V car battery charger is very common. A distinctive feature of these modifications is the presence of a converter. Do-it-yourself charging for a car battery with rotary-type regulators.
Transformers are standard step-down transformers. Resistors for models applyinverter or phase type. If we consider the first option, then the capacitors are installed with a lining. The conductivity index on the winding should not exceed 5 microns. It is also important to check the negative resistance of the charger. Clamps on the model are installed last.
Homemade modifications for 12 V
Homemade 12V car battery charger consumes quite a lot of electricity. To make the modification yourself, you will need a step-down transformer. Resistors can only be used pulse type. In total, two capacitors are selected for the model.
An expander is used to increase conductivity. The stabilizer is installed behind the lining. Negative resistance in the circuit should not exceed 40 ohms. Regulators are used both rotary and push-button type. The first option involves the use of a converter. Modifications with push-button controls are rare. To install them, special tetrodes are soldered. At the end of the work, it remains only to connect the clamps for connecting to the battery.
