- * Battery info for all Volteer battery types. Note that the fields

- * 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.
