I have a device which takes a lithium coin battery which has been acting erratically for at least a year. Back then, I tested the battery which showed 3V, which is the correct amount so I assumed the circuit board was cracked and just lived with it the best I could. Well, last week on a lark I put in a new battery and it works like brand new; old one still tested good at 3V though.
Is it possible for the voltage on a lithium batt to read at spec but be bad, kind of like cold cranking amps on a flooded car battery not able to start a car in at cold temps but still have 12V?
