can anybody share a battery_level_in_percent for AA battery?

[sosse]

Is there a function like battery_level_in_percent for AA battery? I know battery_level_in_percent is only for CR2032. Even though I compensate it to make it 3V from AA battery, the discharging graph is little bit different from CR2032.
