    Look at the bottom picture I posted, does the back look similar?

    I'm not certain, but I think it is oil filled like an Uwatec. Battery can't be replaced.
    There was a reason I never changed mine, I think that was it.

    Can't say the same thing about mine. Regardless of whether the unit was oil-filled, the battery compartment was sealed.

    I am still waiting for the OP to show us the back of his.

    What I don't show here is that I turned the unit on prior to taking these pictures, and it started and continued dive time throughout the photoshoot.

    At this posting, it is showing a 33 minute dive.

    Here is a picture of the back of the unit. It is not oil filled. I think the little gray port is an overpressure plug and the large one in the center is a pressure activated switch. I don't see a way to get to the battery, except perhaps the screw-on face, but that is probably glued in place and I have not monkeyed with it yet. Any ideas?

    I'm certainly not an expert, but is that a battery compartment?

    Could you use a tool like this, and what appear to be two holes, and unscrew it?

    Not a battery compartment, but a pressure activated switch. Great little tool there, I made one but yours looks slick.
