How to Change Batteries for a Uwatec Aladin Nitrox Computer

Aladin Prime and Aladin Tec are dive computers manufactured by Uwatec. They incorporate nitrox functions to enable them to be used for dive planning with nitrox, which enables the diver to plan longer bottom times. The battery in the computers is user-replaceable, with the battery compartment located on the rear of the device. You have to take care to prevent leaks and avoid damaging the components of the computer.

Instructions

    • 1

      Dry the Aladin Dive Computer with a soft towel, then turn the battery cap on the base of the computer counter-clockwise. Use a coin or the Scubapro universal tool. Remove the cap when it's loose.

    • 2

      Remove the o-ring carefully, taking care not to damage the sealing surface of the computer.

    • 3

      Lift the battery out of the computer--avoid touching the contacts as you remove the battery. Place the new battery into the battery slot in the computer, with the "+" sign pointing outwards.

      Replace the o-ring in the o-ring groove. Before inserting it, ensure that the o-ring has no dents in it and that the o-ring, o-ring groove, and the sealing surfaces are free of dust and dirt.

      Push down the battery cap firmly. Turn it clockwise until the marking circles on the cap and the computer are aligned. Do not force the cap beyond the circles, as this can break it and void the warranty. After battery replacement the Aladin will perform an 8-second test and give a beeping sound when the test is done.
