battery should be conditioned in this way regularly to maintain its useful life. In addition to initial use, condition a
battery when it is unused or stored for two months or when its run time becomes noticeably shorter.
To optimize a battery, follow this procedure:
1. Disconnect the monitor from the patient and stop all monitoring and measuring procedures.
2. Place the battery in need of optimizing into the battery compartment.
3. Connect the monitor to AC power supply. Allow the battery to charge uninterrupted for at least 6 hours.
4. Disconnect the monitor from the AC power supply and allow the monitor to run on battery power until the
battery is depleted and the device shuts off.
5. Return the monitor to the charger stand and connect it to the AC power supply. Allow the battery to charge
uninterrupted for at least 6 hours.
8.4 Checking Battery Performance
The performance of a battery may deteriorate over time. To check battery performance, follow this procedure:
1. Disconnect the monitor from the patient and stop all monitoring and measuring procedures.
2. Place the monitor in the charger stand and connect it to an AC power supply. Allow the battery to charge
uninterrupted for at least 6 hours.
3. Disconnect AC power and allow the monitor to run on battery power until it shuts off.
4. Make note of the monitor operating time on battery power. Operating time is a direct indicator of battery
performance. If you notice declining battery operating time span, you may need to run it through an
optimizing cycle or replace it.
Caution: Battery operating time depends on the configuration and operation of the monitor. For example,
continuous monitoring of NIBP and SpO

will deplete the battery faster than occasional vital signs spot
checks.
8.5 Disposing of Batteries
Batteries that are damaged or depleted should be replaced and discarded properly. Dispose of used batteries
according to local regulations.
Caution: Battery service life depends on how often the monitor is used and how many features are used.
The battery typically can be charged and discharged 300 times.
Warning: Do not disassemble batteries, dispose of them in fire, or cause them to short circuit. They may
ignite, explode, or leak, potentially causing personal injury.
