Replacing the 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.

Ruskin software estimates the remaining battery life during deployment by tracking power consumption in mAh. When setting up your deployment on Ruskin, check "Fresh" to indicate that new batteries are installed.

If using the same batteries for a subsequent deployment, do not check "Fresh" and continue power tracking from the previously recorded level.

See Ruskin User Guide: Standard Instruments3 for more information on predicting battery life.

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 D-type cell batteries.

  4. Check for correct battery polarity.

  5. Insert the battery carriage in the instrument and return the end-cap back in its place. See Closing the instrument.

Always remove the batteries from your instrument during long-term storage!
Doing so will prevent internal damage due to battery leakage and/or corrosion.
