5. Connect the monitor to AC power. Fully charge the battery again for use or charge
it to 40 – 60% for storage.
NOTE
•
Do not use the monitor to monitor the patient during battery conditioning.
•
Do not interrupt battery conditioning.
19.8.2 Checking Battery Performance
Life expectancy of a battery depends on how frequent and how long it is used. For a
properly maintained and stored lithium ion battery, its life expectancy is about 3 years.
For more aggressive use models, life expectancy can be less. We recommend replacing
lithium ion batteries every 3 years.
You should check the battery performance every three months or if you doubt that the
battery may fail.
See steps 1 to 5 of 19.8.1 Conditioning the Battery to check battery performance. The
operating time of the battery reflects their performance directly. If the operating time of
a battery is noticeably shorter than that stated in the specifications, the battery may
reach its service life or malfunction. If the battery performance meets the requirement,
fully charge the battery again for use or charge it to 40 – 60% for storage.
NOTE
•
Battery operating time depends on equipment configuration and operation.
For example, high display brightness or measuring NIBP repeatedly will
shorten the battery operating time.
19.9 Storing Batteries
When storing batteries, make sure that the battery terminals do not come into contact
with metallic objects. If batteries are stored for an extended period of time, place the
batteries in a cool place with a partial charge of 40% to 60% capacity.
Condition the stored batteries every three months. For more information, see
19.8.1 Conditioning the Battery .
NOTE
•
Remove the battery from the equipment if the equipment is not used for a
prolonged time (for
example, several weeks). Otherwise the battery may
overdischarge.
•
Storing batteries at high temperature for an extended period of time will
significantly shorten their life expectancy.
