If you get familiar with the battery indicator, you can replace the battery before it dies in the middle of your round.
Replacing the Callaway Diablo Octane Battery
- Open the battery chamber cover – Use the ball of your thumb or a coin inserted into the recessed part of the battery cover, to rotate the cover in the direction indicated by the Open/Close arrow. It may not open easily due to its rubber packing for water resistance.
- Replace the old battery with a new one – Install new battery with the [+] and [-] correctly positioned following the “Battery installation” indication seal in the battery chamber. (The [+] pole goes towards the insider of the chamber.)
- Close the battery chamber cover – Align the Open/Close indicator with the white dot and insert the battery chamber cover. Using the ball of your thumb or a coin, turn the cover in the opposite direction to the arrow indicator. It may not close easily due to the rubber packing for water resistance, but continue to turn it all the way until it stops. Confirm that the cover is securely closed.
