7.5 Battery Maintenance
7.5.1 Conditioning a Battery
A battery should be conditioned before it is used for the first time. A battery conditioning
cycle is one complete, uninterrupted charge of the battery, followed by an uninterrupted
battery discharge and charge. The battery should be conditioned regularly to maintain its
useful life.
To condition a battery:
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. Insert the battery in need of conditioning in the battery slot of the monitor.
4. Connect the monitor to the AC power. Allow the battery to be charged uninterrupted
for 6.5 hours until the battery is full.
5. Remove the AC power and allow the monitor to run from the battery until the
battery is completely depleted and the monitor automatically shuts off.
6. Again connect the monitor to the AC power. Fully charge the battery again for use or
charge it to 40 – 60% for storage.
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 fully charged. Please
replace the battery if its operating time is significantly lower than the specified
time.
7.5.2 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 the
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.
