Replacing the batteries

Refer to Opening and closing the instrument for details on accessing the batteries.

RBR ships new instruments with fresh, highest capacity batteries included. Replace the 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.

Replacing the batteries

  1. Remove the battery end-cap.

  2. Using both thumbs, press down on the "+" symbols on the battery cover and slide in the direction of the arrow.

  3. Remove the eight old batteries from the battery carriage.

  4. Insert eight new batteries.

  5. Check for correct battery polarity.

  6. Put the end-cap back on the instrument and twist clockwise until aligned with PAUSE.

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