When and how to check the battery?
For the professional technicians out there, we need to call on you. We need better criteria than these. What condition should you put the battery in before testing? Should the battery be fully charged before it is tested? Is there a way to test a battery that has not been charged or one that is in a state of mid-charge? What is the acceptable range of voltages? Below what voltage should the battery be removed from the device and replaced?
Is this a good question?
