Your iHealth blood pressure monitor runs on 4 x AAA alkaline batteries. When the low battery symbol appears on the display, replace all four batteries before taking your next reading.
How to replace the batteries
- Turn the monitor over so the back is facing up.
- Open the battery cover on the back of the monitor.
- Remove all four old batteries.
- Insert four new AAA alkaline batteries, matching the polarity (+/-) markings inside the compartment.
- Replace the battery cover.
- Turn the monitor on by pressing the Start/Stop button to confirm it powers up correctly.
⚠️ Do not use rechargeable batteries — they are not suitable for this monitor and may cause inaccurate readings or damage the device.
After replacing the batteries
The date and time on the monitor may need to be reset after a battery change. The monitor syncs its date and time automatically when connected to the Lark app — take a blood pressure measurement and your reading will sync to Lark, which will update the date and time on the device.
💡 If you will not be using the monitor for a month or more, remove the batteries to prevent leakage that could damage the device.
Battery life
A fresh set of batteries supports approximately 250 readings under normal use.
