11.8.2 Battery Performance Conditioning
Condition batteries when they are put into use for the first time. A complete battery
conditioning cycle is: uninterrupted charging, followed by uninterrupted discharging until the
ventilator shuts off, and then uninterrupted charging. Condition batteries regularly to
maintain their service life.
NOTE
 Condition batteries every time when they have been used for three months or when
the battery running time becomes noticeably shorter.

Over time and with the use of the battery, the actual battery capacity will decrease.
For an old battery, the battery full icon does not indicate that the battery capacity
or battery running time still meets the requirement specified. When conditioning
batteries, replace the battery when its running time becomes noticeably shorter.
Follow these steps to condition batteries:
1. Disconnect the patient from the ventilator.
2. Connect the ventilator to the AC power source and charge the batteries uninterruptedly
for at least 10 hours.
3. Disconnect the AC power source. Allow the ventilator to operate on battery power until
the ventilator shuts off.
4. Re-connect the ventilator to the AC power source and charge the batteries
uninterruptedly for at least 10 hours.
5. Battery conditioning is now completed.
11.8.3 Battery Performance Checking
Check battery performance once every six months. Checking battery performance is also
required before ventilator repair is carried out or when battery is doubted to be the source for
ventilator failure. Battery performance may degrade over time.
Follow these steps to check battery performance:
1. Disconnect the patient from the ventilator and shut down the ventilator.
2. Connect the ventilator to the AC power source and charge the batteries uninterruptedly
for at least 10 hours.
3. Disconnect the AC power source. Allow the ventilator to operate on battery power until
the ventilator shuts off.
4. The running time of the battery reflects its performance.
If the running time of the battery is noticeably shorter than that stated in the specifications,
replace the battery or contact the service personnel.
