How is an 18650 battery pack tested?

0:36 vs. 4:47Any cell that displays a value less than 2.5 volts must be thrown away.Anything over 2.5 million

How can I determine the health of my 18650 battery?

The battery cell has seen some drama if its voltage is greater than 4.2 volts or less than 2.6 volts. Any battery that is left outside of this range for an extended period of time is going to experience issues. NOTE: A cell is harmful if its voltage is greater than 4.2. Eliminate it.

What voltage does a defective 18650 battery have?

The charging voltage of 18650 lithium-ion batteries can range from 4.2V to 3V, contingent upon the cut-off voltage specification of the individual cell. Never discharge a cell below 3.0V unless you are aware of its specifications in order to be safe.
