BATTERY MANAGEMENT
Battery Care
Safe, reliable use of the system requires a well designed
battery management program to ensure that adequate
battery power is always available.
ZOLL has developed the ZOLL Battery Management
Program booklet. It includes information for determining
your particular battery requirements and program
implementation steps to setup a comprehensive,
effective and safe program.
For safe disposal of lead acid batteries and disposable
electrodes, follow your national, state, and local
regulations. In addition, to prevent risk of fire or
explosion, never dispose of the battery in a fire.
Battery Life Expectancy
Lead acid battery packs require full recharging after use.
Repeated short cycle recharging will result in reduced
capacity and early battery pack failure.
Frequency of use, number of batteries used for
operation, and the pattern of discharging and recharging
batteries contribute to the loss of battery charge capacity.
Because of this, ZOLL recommends that operators
replace and discard used batteries on a preventive,
scheduled basis. The most effective preventive
replacement interval should be based on anticipated use
patterns, battery pack testing results and experience with
the device in actual operation.
ZOLL recommends battery replacement every eighteen
months or sooner.
Low Battery Message
A “LOW BATTERY” message will be displayed on the
monitor once every minute, and a 2-beep low battery
tone will sound (optionally) once every minute or once
every 5 minutes whenever the unit detects a LOW
BATTERY condition. Replace the battery pack
immediately to ensure continuous operation.
This message and beeping will persist until just before
device shutdown when the unit beeps twice and the
“REPLACE BATTERY” message appears for
approximately 20 seconds.
The time from display of the “LOW BATTERY” message
until the instrument shuts down will vary depending upon
the battery age and condition.
Replace the battery with a fully-charged battery
immediately after the “LOW BATTERY” or “REPLACE
BATTERY” message.
As individual battery capacity diminishes, the amount of
operating time remaining after a “LOW BATTERY”
message also diminishes. For newer or lesser-used
batteries, the operating time remaining after this warning
will be significantly longer than the operating time
remaining with batteries having seen more use. In either
case, this warning will ultimately lead to defibrillator shut-
off, and consequently, the low battery should be replaced
with a fully-charged battery as soon as possible.
Changing the Battery Pack
The M Series products are designed for quick removal
and replacement of the battery pack.
To remove the battery pack, turn the unit off. Insert a
finger into the recess at the left end of the battery pack,
press against the battery pack to disengage the battery
pack locking clip and lift the battery pack out.
To install a battery pack, align the tab of the battery pack
case with the battery pack removal finger recess on the
top of the unit. Set the battery pack into the battery pack
well. The shape of the battery pack will allow the battery
pack to seat itself. Turn the defibrillator back on to the
selected mode of operation.
If the unit is set to PACE mode, pacing may resume
immediately after battery replacement. If this is not
desired, then turn the unit off for more than 10 seconds
WARNING
• Regular use of partially charged battery packs without
fully recharging between uses will result in permanently
reduced capacity and early battery pack failure.
WARNING
• Test batteries regularly. Batteries that do not pass ZOLL’s
capacity test could unexpectedly shutdown without
warning.
