AJAX Button, User Manual, Page: 14 / 15

The pre-installed battery provides up to 5 years of key fob operation in normal use
(one press per day). More frequent use may reduce battery life. You can check
battery level at any time in the Ajax app.
The pre-installed battery is sensitive to low temperatures and if the key fob is
cooled significantly, the battery level indicator in the app may show incorrect values
until the key fob becomes warmer.
The battery level value is not updated on a regular basis, but only updates after
pressing the button.
When the battery has run down, the user will receive a notification in the Ajax app,
and the LED will steadily light up red and go out each time the button is pressed.
