摘要：
A battery pack of a surgical instrument includes a battery, a high range monitoring circuit, and a low range monitoring circuit. The high range monitoring circuit is configured to be activated when an electrical current discharged from the battery exceeds a threshold； and to assess the electrical current discharged from the battery at a first rate. The low range monitoring circuit is configured to be activated when the electrical current discharged from the battery is below the threshold； and to assess the electrical current discharged from the battery at a second rate. The battery is configured to conserve power when the low range monitoring circuit is activated. The low range monitoring circuit is configured to increase the second acquisition rate when the low range monitoring circuit remains activated for a predetermined duration. The first rate is greater than the second rate.
