Battery Information
The logger requires two user-replaceable AAA 1.5 V alkaline or
optional lithium batteries for operation at the extreme ends of
the logger operating range. Expected battery life varies based
on the ambient temperature where the logger is deployed, the
logging or sampling interval, frequency of offloading to the
computer, number of channels that are active, if burst or
statistics logging modes are active, and battery performance.
New batteries typically last 1 year with logging intervals greater
than 1 minute. Deployments in extremely cold or hot
temperatures, a logging interval faster than 1 minute, or a
sampling interval faster than 15 seconds can impact 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 install or replace the batteries:
1. Open the battery door on the back of the logger.
2. Remove any old batteries.
3. Insert two new batteries observing polarity.
4. Reinsert the battery door and snap it back into place.
WARNING: If using optional lithium batteries, do not cut
open, incinerate, heat above 85°C (185°F), or recharge the
lithium batteries. The batteries may explode if the logger is
exposed to extreme heat or conditions that could damage or
destroy the batteries case. Do not dispose of the logger or
batteries in fire. Do not expose the contents of the batteries to
water. Dispose of the batteries 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.
