Even though the battery is showing 0v there probably is still some charge left in the battery, but it has dropped below a voltage at which the battery can now be considered unsafe and the protection circuitry has broken the connection between the battery terminals and the terminals exposed for connections (probably where you are testing). Fwiw they do self discharge at about 2% a year.

In the most basic terms, these batteries can supply about 500 milliamps for one hour before being dead. At the time of exploitation, this parameter is between 13.7 to 14.7 volts.

In The Case Of A 1.5V, This Corresponds To 0.8V, And For A 9V Battery, About 5.4V.

If the battery voltage drops below 9.6 volts during the test, the battery is bad and needs to be replaced. If the battery cannot reach higher than 10.5 volts when being charged, then the battery has a dead cell. If the battery is fully charged (according to the battery.

That may not seem powerful enough to be dangerous? Is 11.9 volts enough to start a car? If the voltage remains about 9.6 volts, the battery is good and can be returned to service.

Test The Voltage Of All The Batteries And If One Or More Is Above ~1.17V While Others Are Closer To 1.10V, Refresh The Dead Cell(S) In A Smart Charger.

In the case of 9v batteries used in smoke alarms, smoke alarms start functioning between 6v to 7.6v. A reading of 9v indicates a battery with no to less than 10% discharge. Can a battery be bad if it reads 12 volts?

However, If The Voltage Drops To Something Below 1.1V Is Already A Dead Battery.

Its hard to use a voltmeter to determine capacity of a lithium battery, but yes 2.85v can indicate a fully depleted battery. It is always a good idea to check the date on the package to get the freshest ones available. Reading 0 volts, chances are the battery experienced a short circuit.
