    \n
    That’s what I thought initially, but [this stackoverflow post](https://electronics.stackexchange.com/questions/250759/how-many-ohm-is-the-adc-port-internal-resistance-of-the-atmega8#250767) dissuaded me. The argument there is that the measurement will be wrong, if the input current is not enough to charge the internal cap within the measurement period. But I’ve done some testing now, and measurements done with 820k and 100k agree well with what my voltmeter measures, so I’ll go with this solution!\n
    \n
    > a fresh alkaline 9V battery is actually 9.6V or more, not 9V.\n
    \n
    Indeed! `9.6V * 10k/92k = 1.04V` is still below 1.1V, so I should be fine in this case :)\n
    \n
    > 9V battery voltages droop noticeably when under load because of their high internal resistance. Make sure to measure under the same conditions.\n
    \n
    This is a good point!\n
    \n
    My firmware will be pretty monotonic though, basically:\n
    \n
    1. wake up\n
    2. measure battery\n
    3. measure some other sensors (the actual task of the device)\n
    4. turn on a transceiver, send all the measurements (including battery voltage)\n
    5. turn off transceiver & go to sleep\n
    \n
    So, the load should be always the same at step (2).

    > You could probably increase the 82K and 10K resistors to be much bigger\n
    \n
    That’s what I thought initially, but [this stackoverflow post](https://electronics.stackexchange.com/questions/250759/how-many-ohm-is-the-adc-port-internal-resistance-of-the-atmega8#250767) dissuaded me. The argument there is that the measurement will be wrong, if the input current is not enough to charge the internal cap within the measurement period. But I’ve done some testing now, and measurements done with 820k and 100k agree well with what my voltmeter measures, so I’ll go with this solution!\n
    \n
    > a fresh alkaline 9V battery is actually 9.6V or more, not 9V.\n
    \n
    Indeed! `9.6V * 10k/92k = 1.04V` is still below 1.1V, so I should be fine in this case :)\n
    \n
    > 9V battery voltages droop noticeably when under load because of their high internal resistance. Make sure to measure under the same conditions.\n
    \n
    This is a good point!\n
    \n
    My firmware will be pretty monotonic though, basically:\n
    \n
    1. wake up\n
    2. measure battery\n
    3. measure some other sensors (the actual task of the device)\n
    4. turn on a transceiver, send all the measurements (including battery voltage)\n
    5. turn off transceiver & go to sleep\n
    \n
    So, the load should be always the same at step (2).
