Guide Measuring state of charge of a non rechargeable CR123A lithium battery
All devices get "leftover" battery charge percentage by simply measuring the voltage. The thing is that batteries when fully charged have a higher voltage and when fully discharged - lower. For example a 12v battery: charged - more than 12.6V, fully discharged 11.6V - 11.8V. A 3.7V battery: (fully) charged - 4.2V, fully discharged - 2.6V - 2.8V.

6 Frequently Asked Questions about “There is a current sound when the rechargeable battery is fully charged”
How do I know if my battery is fully charged?
Once the charging process is complete, the charger will make a different sound than it did when it was first plugged in. Another way to tell if your battery is fully charged is by looking at the voltmeter on the charger. Most chargers will have a voltmeter that displays the voltage of the battery as it charges.
What happens when a battery is fully charged?
Once the battery is fully charged it will not accept any more energy (current) from the charger, since all the energy levels that were depleted when empty are now at their highest level.
How does a battery charger work?
Simpler "chargers" deliver up to a certain amount of current at a fixed voltage delending on what resistance the charging circuit presents to the charger. Once the battery is full, the charging circuit stops drawing power from the charger until such a point where it decids to resume charging.
Why does my Charger make a noise when a plate is saturated?
When the plates are saturated there is no magnetic field to cut and the charger is 'off'. If you leave it long enough the magnetic field will appear again and the charger will be 'on' again. This may account for the difference in noise.
What happens when a battery is full?
Once the battery is full, the charging circuit stops drawing power from the charger until such a point where it decids to resume charging. Assuming a properly functioning charging circuit you cant add excess energy to the battery. There is no redirrcting of energy, the chaarging circuit just stops drawing power from the charger.
How do I set a sound when a battery is charged?
