22.5 Conditioning the Battery
The performance of batteries deteriorates over time. To extend the battery service life, you are recommended to
condition the batteries every three months.
If the battery is not conditioned for a prolonged time, its charge indication may not be accurate and you may
wrongly evaluate the remaining battery runtime.
To condition a battery:
1. Disconnect the equipment from the patient and stop all performances.
2. Allow the battery to be charged uninterruptedly till it is fully charged.
3. Allow the equipment to run on the battery until the battery is completely depleted and the equipment
automatically shuts down.
4. Fully charge the battery again for use or charge it to 40 to 60% for storage.
NOTE
•
Do not use the equipment during battery conditioning.
•
Do not interrupt battery conditioning.
22.6 Checking Battery Performance
Life expectancy of a battery depends on how frequent and how long it is used. When properly used, the
lithiumion battery has a useful life of approximately two years. If improperly used, its life expectancy can be
shorten. We recommend replacing lithium-ion batteries every two years.
The performance of a rechargeable battery deteriorates over time. To extend the battery service life, you are
recommended to check the battery performance
every three months or if you doubt that the battery may fail.
See steps 1 to 3 of 22.5 Conditioning the Battery to check battery performance. The operating time of the
batteries 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 the device configuration and operation. For example, measuring
NIBP repeatedly will shorten the battery operating time.
22.7 Charging the Battery
The batteries can be charged only when they are installed in the equipment or using the charger station
approved by the equipment manufacturer. Batteries charge at a lower rate with the equipment turned on.
22.8 Storing Batteries
When storing batteries, make sure that the battery terminals do not come into contact with metallic objects. If
batteries are not installed in the equipment, and stored for an extended period of time, they should be placed in
a cool place with a partial charge of 40% to 60% capacity (3 LEDs illuminated).
NOTE
Condition the stored batteries every three months. For details, refer to 22.5 Conditioning the Battery .
•
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.
•
The battery storage temperature is between
-
20°C (-4°F) and 60°C (140°F). Storing batteries in a cool
place can slow the aging process. Ideally the batteries should be stored at 15 °C.
