https://devzone.nordicsemi.com/f/nordic-q-a/79613/calculate-battery-using-adcAs 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 batteryen-USTelligent Community 13Tue, 14 Sep 2021 08:36:31 GMThttps://devzone.nordicsemi.com/thread/329345?ContentTypeID=1Tue, 14 Sep 2021 08:36:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:cadea435-f971-4823-98d5-d2e1e7b6753fKarl Ylvisaker<p>Hello,<br /><br />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.<br />Please check the datasheet of the specific battery, and create a similar function that maps the voltage to a remaining charge level.<br /><br />Best regards,<br />Karl</p><div style="clear:both;"></div>
