The lithium ion rechargeable battery that is used in the FreeStyle 5
unit does not need
to be fully depleted before recharging. It is recommended to charge
the battery regardless of the battery’s capacity level after use.
The battery will charge when the unit is off as well as while the unit
is running off the AC or DC power supply.
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 (23°C) ± 2°C.
“No Smoking – Oxygen in Use” signs must be prominently
displayed in the home, or where the oxygen concentrator is in
use. Patients and their caregivers must be informed about the
dangers of smoking in the presence of, or while using, medical
oxygen.
