depletion and the reduction of battery life.
Following the guidelines that we describe in this chapter prevents premature charge depletion
of the battery's charge and reduction of battery's life.
Observe the warnings and cautions and that follow for safe use of the battery:
Warning! If you witness a battery or the battery compartment starting to balloon, swell up,
smoke, or feel excessively hot, turn off the unit, disconnect external power, and observe
it in a safe place for approximately 15 minutes and send the unit for service. Never
puncture or disassemble the battery packs or cells.
Caution Only use the Power Supply provided with the device (
power supply could cause damage or create a fire and/or destroy the battery and ventilator.
Caution Never attempt to completely discharge the battery by shorting it or some other method and never
ship the battery in a completely discharged state.
Caution During continuous, uninterrupted use (>100 hours), you should disconnect the ventilator from
AC power for 30 seconds to allow the battery to run diagnostics while the battery is discharging.
Note:
While the unit is operating on battery power, you can best determine the relative amount of
charge in the internal battery by looking at the BATTERY Icon. The BATTERY icon appears in
outline form and is filled with horizontal rows of lines indicating its current capacity. Each line
represents approximately 5% of battery capacity.
The ventilator monitors temperature and controls the charging and discharging of the battery
under the following conditions:
-20°C to 75°C (-4°F to 167°F) for discharging.
•
0°C to 45°C (32°F to 113°F) for charging.
•
Best operating conditions are 15°C to 40°C (59°F to 104°F).
The battery rapidly recharges to 90% of its capacity in approximately 2 hours. It takes
approximately another 2 hours of trickle-charging to top off the battery to 100% of its capacity.
Continuous charging is permissible with the AC/DC power Supply and 12 VDC Power Cable
that ZOLL provides.

The ZOLL Ventilator continuously monitors the available power sources; occasionally
a false Low Priority power alarm can be triggered for approximately 1 second. These
false alarms immediately clear themselves.
