These symptoms indicate that the battery is no longer safe, and immediate disposal is necessary.

To further evaluate the battery, test its voltage using the multimeter. A healthy battery should hold a charge close to its rated value, usually around 4 to 6 volts for most solar lights. If the voltage is significantly lower, the battery may not hold a charge effectively. In such cases, consider testing the battery under load conditions or performing a full discharge-recharge cycle. This may recondition the battery, extending its operational life. If repeated tests show continued poor performance, replacement is the recommended course of action.

7. EVALUATING THE LED LIGHT

With the solar panel and battery assessed, attention should now turn to the LED light itself. Begin by checking the physical condition of the diode, looking for any visible cracks or burn marks. An operational LED should emit light when the battery is engaged; however, if there is no illumination, further testing is required.

Using the multimeter, measure the current flowing through the LED. This can reveal whether the LED is functioning correctly or if there is an open circuit. A healthy unit typically consumes about 20 to 30 milliamps. If tests reveal no current or significantly low readings, it may be necessary to replace the LED entirely. Properly sealing the LED connections and ensuring a clean installation will prevent moisture intrusion and premature failure.

8. REASSEMBLING THE SOLAR LIGHT

After thoroughly inspecting and repairing any faulty components, you can begin the process of reassembly. Ensure that all components are properly aligned before securing them with screws.
