15-4 Batteries
15.6 Checking Battery Performance
The battery performance may be degraded over time, so you need to check the battery
performance periodically. The checking procedures are shown as follows:
1. Stop the ultrasound exam.
2. Connect the system to the AC power supply to charge the batteries until current
capacity is full.
3. Disconnect the system from the AC power supply to power the system by the
batteries until the system automatically shuts down.
4. The powering time of the batteries indicates the battery performance.
If the powering time of the battery is much shorter than that specified, you may replace the
battery or contact the service personnel.
NOTE:
The usage life of the battery is 300 charge / discharge cycles. If the battery is
improperly used, its life may be shortened.
15.7 Battery Disposal
You need to dispose of the battery when it is damages or severely degraded.
NOTE:
You should observe the local regulations when disposing of the battery.
