What Voltage Should A 3v Battery Read. In this regard at what voltage is a 3 volt battery dead. If the battery tests at less than 13 volts in the multimeter it no longer functions properly and should be replaced.
A practically flat AGM battery at 10 SoC reads 117V to 119V without load. When the battery drops down to 28-27 volt it is considered dead. Battery voltage reacts highly to charging and discharging.
Will you check the voltage before using your new lithium-ion battery.
I have nothing to compare it to. It is good to know the voltage of your new lithium-ion battery before use. You may use a voltmeter to test how much power is left in your alkaline batteries. If the reading is more than 13V for alkaline battery not rechargeable battery then the battery still has some juice left in it.
