Achieving Optimal Performance with Rechargeable
Batteries
To ensure the longest life from rechargeable battery packs, follow these general practices:
DO carry a fully charged spare battery pack at all times.
DO charge battery packs completely.
Whenever a battery pack exchange is required, install a fully charged battery pack.
Use of partially charged battery packs might result in very short run time and unexpected
shutdown.
If you use a partially charged battery pack, fully charge that battery pack before using it again.
Repeated use after partial charging quickly diminishes the battery pack’s capacity, thereby
shortening its life.
If you must frequently use partially charged battery packs, your organization should assess
whether enough battery packs are available to fully support typical rescue activity.
DO implement a means of indicating the charge status of battery packs.
It is important to visually distinguish battery packs that are charged from those that are not.
Establish a system for visually indicating whether a battery pack requires charging or is charged
and ready for use. ZOLL can provide battery pack status labels for this purpose, or you can use
labels or methods of your own.
DO change the battery pack as soon as the message CHANGE BATTERY
appears.
The battery warning ultimately leads to shutdown of the unit. As a battery ages, its remaining
operating time between the warning and shutdown progressively diminishes. Older battery
packs might provide very little run time after the warning and might fail unexpectedly. Always
replace a battery with a fully charged battery as soon as the battery warning appears.
DO test rechargeable battery packs regularly.
Your organization must determine and implement an appropriate testing schedule for
rechargeable battery packs. Conformance to this schedule is crucial for 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 might lose capacity quickly, and so should be tested
more frequently.
DO exchange battery packs regularly.
Exchange battery packs once every shift or once every day, depending on their use.
DO exercise or test battery packs every 90 days (or sooner as they age).
