Checking Battery Charge Level
The installed battery charge level can be checked as follows without
operating the unit:
• When using battery or the DC power cable, momentarily press the
On/Off button. The Standby screen will display for a short period of
time.
• When using the AC power adapter the Standby screen is displayed.
When the unit is operating, the Standby screen is periodically displayed.
Prolonging Battery Life
Do’s
• Fully charge the battery module overnight when you first receive your
transportable oxygen concentrator.
• The battery pack can be charged at any time. The battery does not have
to be fully discharged before attempting to charge. Try to keep your
battery modules fully charged when using the unit.
• Always ensure the battery module is recharged as soon as possible
after it becomes fully discharged. The battery may permanently
degrade if left fully discharged for an extended length of time.
• Check the status of battery module once a month if you are not using
your unit regularly. The battery should be maintained at 2 segments
(approximately 50%) worth of charge.
• Heat is the worst enemy of a battery. Allow plenty of air to circulate
around the transportable oxygen concentrator so that the battery is
kept as cool as possible.
Don’ts
• DO NOT use or leave the battery module in excessive heat or cold.
•
DO NOT store or leave the battery module in car trunks, etc. for
extended periods of time.
•
DO NOT store the battery module fully charged (4 segments on the
unit’s battery gauge) if you are going to store your unit for any time
greater than 2 weeks. Recharge or discharge the battery module to only
2 segments (50% charge) only. Storing a battery with a full charge may
degrade its useful life.
•
DO NOT leave your battery module plugged into the transportable
oxygen concentrator when the transportable oxygen concentrator is
not in use. The battery will lose charge while plugged into the
transportable oxygen concentrator even with the unit turned off.
