When sensors are not used, store the sensors in their charging dock and store in the EVA case of the kit. It is recommended to keep sensors away from magnetic devices to avoid magnetic interference.
How to improve the lifespan of your sensors batteries:
For long period of storage, make sure your sensors are charged often to avoid deeply discharge batteries. Deeply discharged batteries can diminish the life of the batteries. It is recommended to do a full charge on your sensors at least every 1-2 months.
