Why This Kit Matters:

A dive computer is only as reliable as the battery and seal protecting it. An old battery or worn O-ring can lead to power loss, leaks, or costly damage. This replacement kit ensures both your power source and sealing system are refreshed together—protecting your investment and keeping your dives stress-free.

Replacing the O-ring whenever you change the battery is highly recommended, as worn seals are one of the most common causes of dive computer failure.

Key Benefits:

• Reliable Performance: Fresh battery and new seal for dependable dives.
• Protects Your Investment: Prevents water damage, corrosion, and costly repairs.
• All-in-One Convenience: Includes everything you need—no extra parts required.
• Travel Friendly: Lightweight, compact kit is easy to pack as a backup.

Installation Tips:

1. Before removing the old components, clean the battery compartment with a lint-free cloth.
2. Lightly lubricate the new O-ring using the included silicone grease to reduce friction and improve the seal.
3. Carefully seat the O-ring without twisting or pinching it, as this may compromise the watertight barrier.
4. Insert the new lithium battery, close the hatch securely, and test your dive computer before your next dive.
