Is this normal? Due to the limited magnetic contact area, this may occur when testing larger batteries. Before testing, adjust the contact between the battery and the tester's magnetic port to ensure proper contact. Does the complete absence of indicator lights mean the battery is completely depleted? Not necessarily. It could indicate that the tester does not support your battery type, such as 1.2V or 9V batteries. Alternatively, the battery's edge design might be unusual, making it difficult to establish a connection with the tester. Does this tester support CR123A 3V batteries? Currently no. The CR123A battery's negative contact protrudes insufficiently to make reliable contact with the tester's negative (-) terminal. The second-to-last or last indicator light may randomly flash erratically. Is this normal? This is normal, as the battery will behave this way when its charge reaches a critical level.
