Battery Charger Testing: Voltage, Current, Load, Safety

To test a battery charger, use a multimeter to measure its output voltage and current. Ensure the charger’s voltage matches the battery’s requirements. A load tester can evaluate the charger’s ability to charge the battery under different loads. Safety tests, such as short circuit and overcharge tests, can assess the charger’s protection features. By comparing the charger’s performance to industry standards, you can ensure its reliability and safety.
