That gas composition is maintained within the cells throughout shut-down, such as by adding hydrogen to replace any that is consumed by reaction with air leaking into the cells during the period of shut-down. The method includes determining location information of the mobile device, obtaining magnetic field data based on the location information, determining orientation information of the mobile device and applying the orientation information to the magnetic field data to compute a magnetic field corresponding to the orientation of the mobile device.
