I m using STM8L micro controller. This micro controller is powered by 2.4V rechargeable battery. When i tried to monitor the Battery voltage using ADC pin the ADC value remains unchanged due to VCC of the Micro controller is same as ADC input. How can i solve this issue.
 

HI,

use a voltage divider to scale down battery voltage.
Use a reference voltage for the ADC.
