3.5.3 Checking Battery Performance
The performance of rechargeable batteries may deteriorate over time. Battery maintenance as
recommended here can help to slow down this process.
1. Disconnect the patient from the monitor and stop all monitoring and measurement.
2. Switch the monitor power on and charge the battery for more than 6 hours continuously.
3. Disconnect monitor from mains power and let the monitor run until there is no battery power
left and the monitor shuts off.
4. The running time of the battery reflects the battery performance.
If the running time is obviously less than the specified time in the specification, please change the
battery or contact the service personnel.
3.5.4 Replacing the Battery
In monitoring or communication state, the battery status indicator will flash when the battery is
low or empty.
When the lifespan of battery is over, foul odor or leakage is detected, please contact the
manufacturer or local distributor for replacement of battery.
3.5.5 Recycling the Battery
When the battery no longer holds a charge, it should be replaced. Remove the old battery from
the monitor and recycle it properly.
3.5.6 Maintaining the Battery
Batteries should be conditioned regularly to maintain their useful life.
Remove the batteries from the monitor if they are not used for a longer period of time. And
recharge the batteries at a minimum of every 6 months when they are stored.
Discharge the battery completely once every month.
NOTE:
To prolong the life of rechargeable battery, it is recommended to charge it at least once
every month, and it must be done after the electric energy runs out.
