What are the reasons for unstable current in a battery charger?

[Preston]

The reasons for unstable current in a battery charger are: 1. The fuse tube in the battery box is blown or the contact electrodes in the battery box are damaged; 2. There is poor contact in the battery circuit wiring; 3. A single bridge arm of the charger's rectifier tube is open-circuited; 4. There is a component failure in the charger's voltage stabilization circuit or adjustment circuit. Solutions for unstable current in a battery charger: 1. Check the wiring and connectors of the battery circuit to ensure reliable connections; 2. Locate the open-circuit point in the single bridge arm of the charger's rectifier tube and re-solder it. The battery charger uses high-frequency power technology and advanced intelligent dynamic adjustment charging technology, employing a three-stage charging method of constant current, constant voltage, and small constant current. It features high charging efficiency, simple operation, light weight, and compact size.
