Battery Maintenance
The aspirator uses a rechargeable Li-ion battery, which offers a wide temperature operating
range, and a long operating time. Avoid exposing the battery to direct sunlight or heat sources.
Following the guidelines that we describe in this chapter prevents premature depletion of the
battery’s charge and reduction of the battery’s life.
Observe the warnings and cautions 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.
Only use the Power Supply provided with the device . Use of any other power supply could
damage the aspirator or cause a fire and destroy the device.
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 aspirator from
AC power for 30 seconds to allow the battery to run diagnostics while the battery is discharging.
Note:
The aspirator 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.
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 aspirator monitors temperature and controls the charging and discharging of the battery
under the following conditions:
•
Best operating conditions are between 15 to 40°C (59 to 104 °F).
•
-20 to 60 °C (-4 to 140 °F) for discharging
•
0 to 45 °C (32 to 113 °F) for charging
Best operating conditions are between 15 to 40°C (59 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 automotive cable that ZOLL provides.
Note:
When connected to power for an extended period of time (> 30 days), the device
indication may drop below 100% stored charge which allows the battery to perform
diagnostics. To reset, power cycle by removing and reconnecting the connection to
external power. Once this is done, the battery will recharge back to 100% in a few
minutes. Note: If when operating on battery power the device shuts down due to loss of
power, connect external power and power cycle the device to restore function.
Note:
If when operating on battery power the device shuts down due to loss of power,
connect external power and power cycle the device to restore function.
