Step-by-Step Battery Replacement Guide

Step 1: Prepare Your Work Area

Ensure your work area is clean and free of debris. Lay down a soft cloth to prevent scratches on your dive computer.

Step 2: Remove the Battery Compartment Cover

Using a small Phillips screwdriver, gently unscrew the battery compartment cover located on the back of your Suunto D4i. Keep the screws in a safe place as you will need them later.

Step 3: Remove the Old Battery

Carefully use the plastic O-ring removal tool to lift and remove the old battery. Take care not to damage the O-ring or the compartment.

Step 4: Replace the O-ring

Check the condition of the existing O-ring. If it shows signs of wear or damage, replace it with the new O-ring provided in your battery kit. Apply a thin layer of silicone grease to the O-ring to ensure a proper seal.

Step 5: Insert the New Battery

Place the new CR2450 battery into the compartment, ensuring the positive (+) side is facing up. Make sure it is seated correctly to avoid any connectivity issues.

Step 6: Reassemble the Battery Compartment

Carefully place the cover back onto the battery compartment and secure it with the screws. Do not over-tighten, as this can strip the threads.

Step 7: Test Your Dive Computer

Turn on your Suunto D4i to ensure it powers up correctly. Check all functions to confirm that the battery replacement was successful.
