LOWER THAN EXPECTED RUN TIMES
Below are the most common factors that impact how long the Freedom™
ba ery will power a PAP device:
Heated Humidifi ca on & Heated Tubing:
Using these features will
signifi cantly reduce run mes by two thirds in most cases and in some
cases could prevent the ba ery from being able to power the device.
For op mal ba ery performance these features should be turned off .
If heated humidifi ca on is required, lowering the heat se ngs may
help increase run mes; otherwise, two ba eries can be pigtailed
together to increase run mes.
High Pressure Se ng:
Higher pressure se ngs
(above 18 cm/H2O)
can impact run mes especially when other factors are present. All
run me tes ng is done on a pressure se ng of 10 cm/H2O.
Mask Fit:
A leaking mask can impact run mes as the PAP device will
be working harder to maintain the prescribed pressure se ng and
thus be drawing more power from the ba ery.
PAP Device Type:
BiLevel devices will have lower run mes as the
pressure se ng is not constant and changes throughout the night
requiring more power to operate the device. Some older, obsolete
device models and newer targeted ven la on devices require a much
higher power draw than today’s standard CPAP devices and therefore
can result in lower run mes or could prevent the ba ery from being
able to power the device.
Connec on Method:
Some of the connec on components required
to connect specifi c PAP device models do draw power from the
ba ery but this has been factored into the listed average run mes.
DUAL BATTERY CONFIGURATION
While both ba eries are providing output power simultaneously, the
ba ery with the highest charge level will generally be the one to display
“DC 12V” under the ba ery symbol on the digital display screen. Also
note that due to the circuit board diff erences a Freedom™ CPAP Ba ery
cannot be pigtailed with an older model C-100 CPAP Ba ery.
