NOTE
•
The battery charge level indicator does not indicate the capacity or operating
time of the battery. It only indicates the current battery charge level. The
actual battery capacity decreases over time with the use of the battery. For
an old battery, its capacity and operating time may not fulfill battery
specifications even if the battery charge level indicates the battery is in full
charge. Please replace the battery if its operating time is significantly lower
than the specified time.
15.5.2 Checking a Battery
The performance of a rechargeable battery will deteriorate over time. The battery
performance test must be performed once a year, before monitor repairs, or whenever
battery performance is suspect
.
To check battery performance:
1. Disconnect the monitor from the patient and stop all monitoring or measuring.
2. Turn off the monitor. Disconnect the monitor from the AC power.
3. Install the battery.
4. Connect the monitor to AC power. Allow the battery to be charged uninterrupted
for 6.5 hours until the battery is full.
5. Note the time. Remove AC power and allow the monitor to run from the battery
until it shuts off. Note the time again. Calculate the run time by subtracting the
start time from the end time.
The operating time of a battery directly reflects its performance. If the operating time of
a battery is noticeably shorter than that stated in the specifications, contact Mindray or
your service personnel.
NOTE
•
The battery may be damaged or may have malfunctioned if it only operates
for a short time after being fully charged. The operating time depends on the
configuration and operation. For example, measuring NIBP more frequently
will also shorten the operating time.
•
Replace a battery that has visual signs of damage or no longer holds a
charge. Remove the old battery from the monitor and recycle it according to
local laws.
15.6 Recycling a Battery
Remove the old battery from the monitor and recycle it properly. Follow local laws for
proper battery disposal
