+ * Battery info for all Treeya battery types. Note that the fields

+ * 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.
