Weak or mixed batteries can cause device problems or interrupted measurements.
Why it matters
Follow the manual for battery type, replacement, and storage.
A practical routine
- Replace a full set together when instructed.
- Do not mix old and new batteries.
- Remove batteries for long storage if recommended.
Make the record useful
Use a correctly fitted upper-arm cuff, sit quietly with supported posture, and record paired readings when recommended. Add short context notes when needed.
