battery has a useful life of approximately two years. For improper use models, life expectancy can be less. We
recommend replacing lithium-ion batteries every two years.
The performance of a rechargeable battery may deteriorate over time. You should check the battery performance every
two months or if you doubt the battery may fail.
Refer to Steps 1 to 5 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, discard the batteries
or contact your service personnel.
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, high display
brightness or measuring NIBP repeatedly will shorten the battery operating time.
21.7 Storing the Battery
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
(3 LEDs illuminated).
Stored batteries should be conditioned every 2 months. Refer to 21.5 Conditioning the Battery for details.
NOTE

Storing batteries at high temperature for an extended period of time will significantly shorten their life
expectancy.

Storing batteries in a cool place will slow the aging process. Ideally the batteries should be stored at 15. Do
not stored the batteries in an environment above 60
℃
or lower than -20
℃
