[Read the Important Safety Rules section before operating this equipment.]
Charging of the battery may take several minutes after connecting the power to initiate, depending on the
battery's internal operating temperature. This is a normal condition and is intended for safe battery
charging. This circumstance is more likely when the battery has been fully discharged.
If the device power supply remains connected when the battery is fully charged, the four LEDs will turn off
within approximately 1 hour.
NOTE
For oxygen concentrators equipped with batteries:
The Oxygen Concentrator battery does not need to be fully discharged before recharging. It is
recommended to charge the Oxygen Concentrator battery after each use.
Lithium batteries may permanently lose capacity when exposed to extremely hot temperatures with the
batteries fully charged or completely depleted. For extended storage, it is recommended that batteries be
charged 25 to 50% and remain within a temperature range of 73°F ± 35°F (23°C ± 2°C).

While charging a fully discharged battery, initially the 25% LED will start blinking rapidly for a few minutes,
•
then start to blink at a slower rate every (1/2 second).
The LED will continue to blink until 25% capacity is reached. The LED will then turn solid.
•
Each of the four LEDs, 25% -100%, will blink as stated above, then turn solid when they reach their
•
capacity.
When all LEDs illuminate solid, the battery is fully charged and the LEDs will remain solid for a period of
•
time, then all four LEDs will turn off.
