Q1: What should I do if the battery has no response and the screen doesn't light up?

A: Follow these steps to troubleshoot:Confirm if the battery model is on the support list, unsupported models cannot be testedCheck if the positive and negative terminals of the battery are installed in reverse and if they are fully attached to the contactsWipe the battery contacts and metal contacts of the tester with a dry cloth to remove the oxide layerReplace the battery with a brand new one that is confirmed to be charged for testing, and eliminate the problem of the battery itself being deadIf all the above operations have been tried but there is no response, please contact customer service and send a video of the operation, and we will help you with after-sales service.

Q2: The test results do not match the actual usage experience, such as displaying full power but the device cannot be used?

A: This situation is mostly due to battery issues. The tester displays the no-load voltage/battery level, while some batteries are "virtual":Old/inferior batteries may have sufficient voltage but cannot carry the load, which is due to the aging/damage of the battery itselfYou can compare and test with a new battery to see if the tester displays normally
