   * Battery info for all Grunt battery types. Note that the fields
   * start_charging_min/max and charging_min/max are not used for the charger.
   * The effective temperature limits are given by discharging_min/max_c.
   *
   * Fuel Gauge (FG) parameters which are used for determining if the battery
   * is connected, the appropriate ship mode (battery cutoff) command, and the
   * charge/discharge FETs status.
   *
   * Ship mode (battery cutoff) requires 2 writes to the appropriate smart battery
   * register. For some batteries, the charge/discharge FET bits are set when
   * charging/discharging is active, in other types, these bits set mean that
   * charging/discharging is disabled. Therefore, in addition to the mask for
   * these bits, a disconnect value must be specified. Note that for TI fuel
   * gauge, the charge/discharge FET status is found in Operation Status (0x54),
   * but a read of Manufacturer Access (0x00) will return the lower 16 bits of
   * Operation status which contains the FET status bits.
   *
   * The assumption for battery types supported is that the charge/discharge FET
   * status can be read with a sb_read() command and therefore, only the register
   * address, mask, and disconnect value need to be provided.
