 DON’T remove a partially charged battery pack from the battery charger.
If a partially charged battery pack is used, a full charge is recommended before its next use. Repeated use after partial charging
will quickly diminish the battery’s capacity, thereby shortening its life.
 DON’T store battery packs in a discharged state.
Battery pack capacity will diminish if left in a discharged state for extended periods.
 DON’T assume that a shift check of the Monitor/Defibrillator verifies adequate battery pack run time.
Your Monitor/Defibrillator should be tested daily to verify the readiness of the device. This test, however, does not verify
adequate charge state or capacity of the battery pack and may leave the Monitor/Defibrillator with inadequate run time.
If the device shows a “LOW BATTERY” warning during testing, the battery pack should be replaced and recharged.
 DON’T place battery packs charged with a Base PowerCharger 4x4 , a PowerCharger or a PD 4420C
(constant current chargers) into the PD 4420 or Single Battery Charger (constant voltage charger) without
providing a rest period of at least 12 hours.
This will result in damage to the battery packs.
 DON’T charge battery packs at temperature extremes.
ZOLL recommends charging battery packs at or near normal room temperature (15°C to 35°C or 59°F to 95°F).
 DON’T leave batteries in a depleted state.
Once a battery is removed from the device it should be immediately placed in a charge or test well. Idle batteries will lose some
of their charge and may suffer damage to charge capacity if left in a discharged state.
