Replacing batteries

RBR ships new instruments with lithium thionyl chloride batteries included. Replace batteries before each deployment to maximise the operational time and prevent data loss.

To replace the batteries:

1. Remove the battery end-cap and pull out the battery carriage. See Opening the instrument.
2. Remove the 24 old D-type cell batteries.
3. Insert 24 new LiSOCl2 D-type cell batteries.
4. Check for correct battery polarity. 
5. Connect the internal cable.
6. Insert the battery carriage in the logger and return the end-cap back in its place. See Closing the instrument.
