A simple car battery charger. Only two parts.
ATTENTION! There is a phase potential on the battery terminals, so installation and connection must be performed when disconnected from the 220 volt network!!! A simple charger for a car battery. Two parts are used. A semiconductor diode for a current of 1 ampere and a voltage of 200 volts. If a 75 watt lamp is used, the charging current reaches 0.15-0.17 amperes. At this current, the battery will not boil, and in an hour or two, it will restore its capacity, sufficient to start the engine. It is not advisable to constantly charge with such a device, only in situations when it is urgently necessary to recharge your car battery. Do not repeat if you do not have knowledge of electrical engineering and electrical safety!!!!
