Calculate battery using adc

[Judge]

As known in SDK nrf there is a function battery_level_in_percent() used to calculate battery percentage but it is only true for the CR2032 battery. Currently, I am using AAA battery so is there any way I can calculate the percentage of the remaining battery by measuring the Vdd pin ADC?

Hello,

To calculate remaining charge from the measured voltage of your battery you will need to check the discharge curve of the specific battery you are using.
Please check the datasheet of the specific battery, and create a similar function that maps the voltage to a remaining charge level.

Best regards,
