Standard Charging
Whenever a logger is reconnected to the charger it will begin
the 16-hour charge cycle, no matter what the status of the
battery. Once the charging cycle is complete the logger will
run from external power supply.
Effect of Charging Battery on Temperature
Sensor
For loggers measuring data with the internal temperature
sensor, it is critical to note that during the charge cycle the
logger will heat up thereby causing the internal temperature
sensor reading to rise by up to 10
˚ C above ambient
temperature. Once the charging process is complete, the
logger will cool down and the internal temperature sensor
readings will return to normal.
For loggers remaining connected to AC power, to prevent the
logger from heating up again following the initial charge cycle,
the logger will receive a one minute
trickle charge
each day
rather than stay continually charged. This is sufficient to
ensure the logger doesn’t self-discharge and will maintain the
logger’s full charge status.

Data Loggers
The Mini DataNet loggers are powered by non-rechargeable
internal 2/3 AA lithium batteries. There is no external power
supply for these loggers.
Depending on the logger configuration, the battery can last up
to 10 months before they need to be replaced.
Replacing the Mini DataNet Battery
To replace the batteries on the Mini DataNet loggers, remove
the two screws located on the top panel of the logger (where
