:
The following figure illustrates the effect of lowered battery capacity on the monitor/ defibrillator operating time
remaining after the LOW BATTERY warning.
• DO test battery packs regularly.
Your organization must determine and implement an appropriate testing schedule. Adherence to this schedule is
crucial to identifying battery packs that have reached end of life and should be removed from use. Battery packs
subjected to repeated short discharge and charge cycles may lose their capacity quickly. Test the battery packs that
you use this way more frequently.
• DO implement a means of indicating the charge status of battery packs.
It is important to visibly distinguish battery packs that are charged from those that are not. Establish a system for
visually indicating whether a battery pack is charged and ready for use or is in need of charging. ZOLL can provide
you with battery pack status labels for this purpose, or you can use labels or methods of your own.
Achieving Optimal Battery Pack Performance
The following general practices will ensure the longest life from your battery pack:
“Do’s and Don’ts” in using battery packs:
• DO charge battery packs completely.
When a battery pack exchange is required, place a fully charged battery in the unit.
If you use a partially charged battery pack, it may result in a very short monitor/defibrillator run time.
If a partially charged battery pack is used, a full charge is recommended before its next use. Repeated use after
partial charging quickly diminishes the battery pack’s capacity, thereby shortening its life.
Frequent use of partially charged batteries requires reassessment as to whether enough battery packs are in
service.
• DO change Battery Packs when LOW BATTERY warning message appears.
The LOW BATTERY warning ultimately leads to monitor/ defibrillator shut down. As batteries age, the run time
between the LOW BATTERY warning and monitor/ defibrillator shut down progressively diminishes. Older
batteries may provide very little run time between the LOW BATTERY warning and monitor/defibrillator shut
down. Therefore, when the LOW BATTERY warning occurs, install a fully charged battery pack as soon as
possible.
