All dive centres that offer servicing should have the appropriate tools and service parts available at their store. As a well-informed customer, please check with the shop and inspect all their inventory before committing to their services. If a dive centre has their own facilities, insist that they do the changing of batteries in front of you and personally witness the watertight testing in their chamber facilities.

Only authorized battery kits are used when replacing batteries in  dive computers and instruments. Not all batteries perform the same and the batteries supplied in these kits have been tested for suitable performance. The kits include all the parts that should be replaced once the battery compartment has been opened.

Your computer’s watertight seals are critical. That’s why a battery replacement isn’t just changing the battery. The battery compartment o-ring will be replaced, and in some cases even the battery compartment door is replaced. Zoop, Mosquito (D3), Stinger, Spyder, and D-series computers get leak tested in the Witschi Proofmaster S and all computers are test dived to 130′ (40m) in a state-of-the art pressure pot to check all computer functions.
