Battery Management

Figure 1 illustrates the effect of lowered battery capacity on the Monitor/ Defibrillator operating time remaining after
“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. Battery packs used this way should be tested 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.
• DO exchange your battery packs regularly.
Battery packs should be exchanged once per shift or once per day depending on their use.
• DO carry a fully charged spare battery pack at all times.
