Integrated Battery System
The Integrated Battery System consists of two independent but
coordinated lithium ion batteries, the Power Pac, located on the back
of the ventilator and the Backup Battery inside the ventilator. The
Integrated Battery System can provide up to 10 hours of operation at
standard settings* when new and fully charged. This system assures
continued support during transport, daily activities or power outages.
The Power Pac is “hot-swappable”. The Backup Battery will provide
a minimum of 30 minutes of back up power during Power Pac swaps
or power outages. Proper care and maintenance of the Integrated
Battery System will ensure the longest life.
NOTE: Always plug the HT70 into an external power source when
available. Plug the HT70 into external power source even when not in
use to insure best battery performance. Check battery capacity on
the front panel before removing from external power.
Power Pac Battery Pack
The integrated Power Pac battery pack is a detachable “hot-
swappable” battery. You can easily slide it out and replace it with a
fully charged battery pack – without interrupting ventilation.
Charge the Power Pac for a minimum of 3 hours for 100% recharge.
If the battery charge is not fully depleted, the charge time may be
less.
NOTE: It’s a good idea keep an extra Power
Pac with the HT70 ventilator.
When the HT70 is used for transport
applications, ensure that the Power Pac
battery pack is fully charged prior to use. It
is highly recommended to carry an extra fully
charged Power Pac during transport or outdoor applications.
