A pulse charger is a device that charges energy into a battery by charging an electric current into the battery. It is a device that converts alternating current into low voltage direct current. It is distinguished by the way it is charged. It is different from other charging methods.

So how do you distinguish between a pulse charger and a constant current charger?

Make a 10 turn solenoid with a 2.5mm2 BV line, and put a compass near it. Connect a car with an incandescent light bulb (12V or 6V) and connect the battery charger to the charger, when the compass is directed to the solenoid, indicating that the charger is a constant current charger". If the compass points to the solenoid with a certain angle or repeated oscillation, it means that the charger is a pulse charger".
