Keep the Lithium battery stocks dry. High moisture levels damage connectors between it and the connector and that can lead to safety risks or unit failure. If possible avoid using it in damp places.
When you store it, make sure the temperature is not too high nor too low. Don't freeze it and storing the unit in a hot car or near the radiator is a bad idea as well. Use a sealable bag, charge the battery to about 50% and put it into the fridge between 0 and 5C.
