Battery Information
The logger is installed with a 3V CR2032 battery (HRB-TEMP).
Expected battery life varies based on the ambient temperature
where the logger is deployed, the logging interval, the rate of
state changes, the frequency of offloading to the computer,
number of channels that are active, and battery performance. A
new battery typically lasts 1 year with a logging interval greater
than 1 minute. Deployments in extremely cold or hot
temperatures or a logging interval faster than 1 minute may
reduce battery life. Estimates are not guaranteed due to
uncertainties in initial battery conditions and operating
environment.
The logger can also be powered by the USB cable when the
remaining battery voltage is too low for it to continue logging.
Connect the logger to the computer, click the Readout button
on the toolbar, and save the data as prompted. Replace the
battery before launching the logger again.
To replace the battery:
1.
Open the battery door on the top of the logger.
2.
Use the tab on the built-in battery removal tool inside the
compartment to remove the battery.
3.
Place the circular battery removal tool around the negative
side of the new battery with the tab up. Insert the new
battery with the positive side facing out. 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.
