Use them as one would normally use them. But make sure before you launch, check the battery/cell voltages, compass and IMU values, BEFORE lift off...
If all is happy, then you should be good to go.
I would set my battery(s) "default discharge cycle" to 3 days (using the DJI Assistant). and then go as you do.
If you are "planning" on not flying for an extended period of time, (due to weather etc.) just charge them and you can auto discharge them about every 5/6 weeks.
That's my model...
