    Has anyone replaced a battery on the D9 or similar? SimplyScuba are quoting £60. Just wondering if it's feasible to change it myself? I suppose the fee is security for a guaranteed job, but seems quite steep.

    Well, the bits are on eBay for under a tenner but you have to ask yourself two questions;
    1. Can I open it without damaging it?
    2. Can I be sure I reassembled it correctly and it's watertight?
    Simply Scuba's price should include a pressure test which will show as a deep dive on the computer.

    A decent jewellers could probably do it for a lot less, but their pressure test, if they do one, probably won't be as deep.

    Have you asked if NDAC can do it? It's a good excuse to rob SWMBO's car and head over for another dive.

    Hmm, put that way it's worth it!

    (Does he mean Simply or NDAC:)

    Post a pic of the back case, it'll be a very easy and straightforward job.

    It may need a speshul tool to get the back off; the old D9 certainly does.

    Yeah like all of my watches need special tools. Rado for example charge £175 for a new battery, I bought a pack of 10 identical ones and watch toolkit for less than a tenner and did it myself. As long as the seal is seated correctly and clean the battery will be easy to do.

    I'm sure I could have done it. However, I've sent the thing off 'cos I'd like the warranty.

    But, good news... I'm now first on the list for next X-Deep Black that comes in to Aquanauts! I've only been waiting since June:) I got to use one over the weekend - how wonderful that one can see the screen whilst underwater. Unlike the D9tx which is, to be blunt, totally sodding useless for UK diving.

    Oh, and whilst whinging about Suunto... The way that the battery warning works is cack: go to Dive mode and crash, the whole thing is bricked. If it weren't for Doom & Becs giving me a lend of their bottom timers, I'd not been able to dive.

    I got the computer back from Simply Scuba. Three days in total, pretty good going considering that includes the time to send it both ways.

    It shows a dive to 30 metres with a rapid ascent alarm, so has been pressure tested.

    Nah, nothing interesting. Just a free ascent in zero viz thanks to the run-off from the torrential rain. No fizzing.

    Besides, you'd need a couple of scooters each to even get close to Dave's record. :D

    Resurrection...

    Still have the D9tx and the battery went whilst in Scapa. Found the local dive shop there (can't remember the name, but brilliant!) had a repacement battery. Local hardware shop had a screwdriver. Battery replaced for a tenner.

    Battery went again yesterday whilst at NDAC. Asked for another battery but they're out. She mentioned that apparently the Duracell battery doesn't fit. Hmm.

    From Wikipedia and here..
    • CR2450N means
      • C = Lithium + Manganese Dioxide, nominal voltage = 3v
      • R = Round
      • 24 = 24mm diameter
      • 50 = 5mm high
    • However... The real dimensions aren't quite that...
      • 24 = 24.5mm

    A quick google shows some people claiming differences between CR2450 and CR2450N. Can't find any info but this appears to support differences.
    • the CR2450 battery appears to be different to a CR2450N battery but can't find how.

    Bottom line...
    The previous battery I bought in Scapa was a Renata CR2450N. It worked. Bought two from Amazon for £5.

    And pop the additional ‘fee’ into your box fund.

    Give it ten to fifteen years and you might have surreptitiously squirreled away enough cash to buy a broken Inspo.

    Just sell the D9tx and that'll get you a few quid

    Trouble is I use the Suunto as a watch which also happens to log my dives. I'm sure if I got rid of it I'd end up getting some kind of analogue watch and goodness knows how much that will cost!

    Batteries arrived; will change it tonight.

    Under a tenner, unless you're an insufferable watch bore.

    Well, I can save that tenner now. Suunto's working again.

    I think there's only one scuba shop in Scapa. Imaginatively named... "Scapa Scuba"
