各位大神：
有没有用过CSI2130 battery discharge这个功能键？能介绍一下使用时的注意事项吗？谢谢！

刚刚找到注意事项，和大家一起分享一下。
Battery Discharge (CSI 2130 with Ethernet port and SD slot only)
When the external power supply/charger is plugged into the CSI 2130 the battery
charge circuit has the ability to control a battery discharge. Discharging
the pack allows the gas gauge circuitry to be calibrated. During the discharge
cycle the charge circuit monitors the voltage of the battery pack and terminates
the discharge once the pack is discharged. Once the pack is discharged,
the charging circuit automatically stops the discharge and starts charging in
fast mode.
The gas gauge circuitry exists to provide information about the status of the
analyzer’s battery pack. The primary purpose is to report the amount of
charge remaining in the battery pack. Additional information includes how
many times the pack has been charged since it was calibrated, how much
charge was available after the last “Last Measured Discharge” (a calibration
cycle), and other status information. The Gas Gauge IC also has an
“EMPTY” output pin that is wired to the analyzer.
Discharging the battery is not a trivial task. The amount of time require to discharge
and recharge the analyzer will vary between 16-30 hours depending
on the initial charge level of the battery, the condition of the battery, and the
hardware revision of the CSI 2130. Therefore, initiate the discharge when you
have enough time to do so, such as over night or over the weekend.
