Read MoreHow to diagnose whether the downhole high temperature lithium battery is faulty?
Measure the output voltage of the battery. If the voltage is abnormally low or fluctuates greatly, it may indicate a problem with the battery, such as an internal short circuit or damage to some cells.
Look for obvious signs of cosmetic damage to the battery such as bulging, distortion, fluid leakage, corroded terminals, and so on.
Use a temperature sensor to monitor the temperature of the battery during operation. High temperatures can be caused by internal short circuits, overheating or poor heat dissipation, which often signals a malfunction.
Observe the discharge current of the battery. Abnormal current patterns, such as too high or too low and erratic currents, may suggest battery failure.
