How to Dismantle an Aladin Pro Dive Computer
Computers are a good tool for dive planning and execution. (scuba diving 01 image by Undy from

The Aladin Pro is a scuba diving computer that allows a diver to make dives up to 100 meters deep. It can be programmed for use with air or nitrox -- air enriched with a higher percentage of oxygen. The unit is sealed, but to replace a worn-out battery it can be dismantled to enable the user to access the interior. The interior is filled with a paraffin-like liquid so care should be taken where the unit is dismantled.

Tips and warnings

  • Do not try to dismantle the unit by sticking a screwdriver in the vent holes in the back. This will break the diaphragm seal.
  • Opening the computer voids any warranty from Uwatec.
  • If you want to replace the battery you must have an identical 3.6v Uwatec lithium battery to solder to the operating system.
  • The unit must be fully immersed in the same liquid it contains before being reassembled.
  • You need to maintain a 3.6-volt charge to the poles when changing the battery to avoid wiping the memory/program.
  • The best option is to pay to have the unit opened by a Uwatec certified technician to avoid any problems.
