Battery Storage
Lithium Ion batteries discharge during storage. Higher temperatures (above 20C or 68F) reduce
the battery storage life.
Follow these rules to ensure the best storage life of the ZOLL Ventilator’s batteries:
1. Always store the ventilator with the battery fully charged. DO NOT store the ventilator with
the batteries discharged.
2. For long-term storage, the optimum storage temperature range is -15 C to 21 C (5 F to 71 F).
Avoid exposing the battery to direct sunlight or heat sources. Never store the battery at
temperatures above 76°C (170°F) for more than 2 hours to prevent premature charge
depletion and the reduction of battery life.
3. If long-term storage/non-use is common, recharge the unit every six months; this ensures that
the battery charge is maintained at 80% capacity or better.
4. When batteries are in extended storage, you should charge them at recommended intervals
when not continuously connected to an external power source:
Note: When charging in the storage case, be advised that the battery may stop charging if
ambient temperature is above 40
C/104F, even though the unit is still connected to
external power. Under these conditions, battery temperature can get as high as 10
C/
50
F above the ambient temperature. Charging automatically starts when the ambient
temperature drops.
