The dilatometer including a controller configured to: receive calibration force readings from a magnetic force sensor, the calibration force readings including magnetic force strength between a magnet of the dilatometer and a magnetic spacer of the battery at different calibration distances resulting from movement of the magnet relative to the magnetic spacer across a distance range during calibration; assign a position value to each one of the calibration force readings, the position value is a distance between the magnet and the magnetic spacer of the battery; and predict magnetic force strength between the magnet and the magnetic spacer across an entirety of the distance range based on the position values of the calibration force readings.",
