    DW-9350 Raysman: solar battery, right?

    AFAIK, the Raysman is a "Tough Solar" G-Shock, with a solar battery (ML2020, if my research is correct). My Raysman has been in my collection since September, 2013, and I wear it regularly, once or twice a month. But lately it was not achieving full charge, so I thought it was finally time for a battery replacement. However, I was having a hard time finding a spare ML2020 battery. So just to be sure, I opened it up to check:

    Yep, that's a regular Maxell CR2016. I bought the watch through eBay, so obviously the previous owner did the battery job. For all I know, if you stick a non-rechargeable battery in a solar-powered module you would fry the battery, fry the module or both. Theory not withstanding, the watch has been working perfectly these last 5 and a half years

    So what should I do now? Use a CR2016 or go after the rechargeable ML2020?

    PS: I made a typo: it's the DW-9350, and not DW-9530, sorry. I corrected the title.

    I'd go for the correct solar battery. I'm sure Yankeexpress will chime in sooner or later. He has quite a few of those and probably knows the correct battery to use. I personally would not use another CR2016.

    On a side note, it's been years since you posted. When I started on the forum I read quite a few of our posts, and your pictures were always very good.

    depends on how many G's you have and how precious this G is in your collection, one of my 2300's has been running on non-solar battery for 2 years now, don't see any problems with it

    take the module out and see if the solar panels are still connected. a previous owner might have seen the price of a rechargeable battery or like you, couldnt find one so he mightve just disconnected the panel and put in the nonrechargeable. it what i wouldve done... and have done ;) lol
    could also explain why it hasnt fried yet too.

    Well, I have more Gs than I should have, that's for sure. But this one is my nicest yellow one, and until now, it was one of my most pristine vintage models.

    The first thing I thought was that the guy disconnected the solar panels, or else it would have fried. But how do I know?

    In the end, being honest, if I can use a regular CR2016 on it, without risk of damaging the module, that's what I would do. The watch was working flawlessly, and I have absolutely no qualms in once every 5 years or so replacing the battery. I've been doing that for years with my regular Gs, so it's no biggy. Besides, I enjoy opening them up and having a look-see to check how the module is holding up and lubing the gasket.

    Well, I couldn't find a definite answer and the watch opened on my workbench was starting to bother me, so I said what the hey:

    Lubed the gasket and used a CR2016. It's been 30 minutes now, and nothing exploded or started melting. So I think I'm okay...

    Nice watch there LUW, also nice to hear your back. Wish I had joined earlier rather than just look occasionally.

    hm. wouldnt risk a wrong battery in this watch, no matter if it was ok so far with a wrong one. if the module is toast, its gone most likely and u will have to find a new raysman module. id invest that 15euros in a fitting battery, really no problem there in ordering one nowadays.
