With the LCD screen still facing up, slide the tray back into
the logger. The LCD should display “HOBO” briefly after
correctly installing the battery.
WARNING:
Do not cut open, incinerate, heat above 85°C
(185°F), or recharge the lithium battery. The battery may
explode if the logger is exposed to extreme heat or conditions
that could damage or destroy the battery case. Do not dispose
of the logger or battery in fire. Do not expose the contents of
the battery to water. Dispose of the battery according to local
regulations for lithium batteries.
HOBOware provides the option of recording the current battery
voltage at each logging interval, which is disabled by default.
Recording battery life at each logging interval takes up memory
and therefore reduces logging duration. It is recommended you
only record battery voltage for diagnostic purposes.
