what is the best way to maintain (2) M9 batteries.
i really only use 1 battery but i will be traveling so just in case bought a second.
should i only start to charge that second battery when i travel and leave it on the shelf before and after my trip, or should i work it into my daily rotation from now on.
not sure what is best for battery longevity.
