Just recently I bought my Mavic Pro with the Fly more combo but for now I'm not going to use the two extra batteries because I don't have free time and the weather isn't the best (raining all the time

Discharge them to 50% and Just keep them in a cool dark place and when you are ready to fly just tapp them to 100%.

Thanks for the answer but the batteries are new! I've never charge them up.

They self discharge to storage level of 10 days not being used, so they are probably at storage level by now. So just store them and charge before use.

The self discharge will discharge them to 65% after 10 days, but I set mine to discharge in 3 days.  The most damage is done to a battery when it is below 20% or above 80%, so if your battery is in that range, don't worry about it.
