If you own an Android device, there’s a good chance that you have an Airpod case battery. If not, you can easily check the battery by using a battery tester. To use the battery tester, first remove the Airpod case from your device. Next, plug in the charger to your device and plug in the Airpod case. Once plugged in, hold down the power button and wait for the indicator to light up. The light should stay on for about 10 seconds or until it turns off. If the light stays on and doesn’t turn off, then your Airpod case battery is good and you can continue using your device with it. If however, the light turns off after a few seconds or when you try to turn on the device again, then your Airpod case battery is not good and you need to replace it.
