Storage

If unused IntelliVue Cableless Measurement Devices are stored for an extended period of time:
• they should be powered off for storage
• they should be stored in a cool place, ideally between 15°C and 25°C (60°F and 77°F)
• the state of charge should be between 40 and 50%
• they should be recharged every six months
Storing in a cool place slows the aging process of the batteries. They should be fully charged prior to
use. Do not store the device at a temperature outside the range of -20°C (-4°F) to 60°C(140°F).
Do not store cableless devices in direct sunlight.
NOTE
Storing the devices at temperatures above 40°C (104°F) for extended periods of time could
significantly reduce the battery's life expectancy.

Battery Lifetime Management

The lifetime of a Lithium Ion battery depends on the frequency and duration of use. When properly
cared for, the useful life is approximately 4 years or 400 complete charge-discharge cycles, whichever
comes first. In addition, experience indicates that the incidence of failure may increase with battery
service life due to the accumulated stresses of daily use. We therefore strongly recommend that lithium
ion batteries be replaced after 4 years or 400 complete charge-discharge cycles.
The age of a lithium ion battery begins at the date of manufacture. To see the date of manufacture and
