    Solar vs. standard battery...What's the deal?

    I don't post here often, but the experts on this forum can probably best answer this one. I have two of the older model atomic / solar models (GW300 I think, see pic below). After about 4 years one of them had a problem staying charged, then just died completey. I sent it in to Casio get fixed, thinking that there was some major problem. They called and said it needed a new battery, and even though they are recharged by the solar capacitor, eventually they run out of juice and need to be replaced. Now...my DW5600 that I bought in the early 1990's had a 10 year battery that actually lasted almost 10 years(and I wore it alot back then). So what is the advantage to the solar? Did I just get a bad one that is the exception? If so, what should the average life of a solar battery be?

    BTW, thanks to some advice from Sjors, I scored a MB Frogman that should be in tomorrow.

    Thanks,

    Don

    your old DW5600 has only basic timing function, and your GW300 has atomic, auto EL, etc

    with rechargeable batteries, your GW300 can sync 5-6 times a night (i forgot exactly how much), and you can use EL numerous of the times without worrying about running down the battery (given that you will wear it under the sun and give it a good charge tomorrow)

    the bad news is that, and it has been covered tens if not hundreds of times, some of the earlier patch of casio tough solar suffers from a bad patch of rechargeable batteries, so many of the rechargeable cell suffers from premature failure. and unfortuniately, earlier GW300 was one of those with the bad rechargeable cells.

    anyway, the current production of tough solar has been much more reliable, and i would pick a solar over battery any day

    Thanks. Looks like maybe I had a dud. So does anyone know the expected life of a solar battery provided it gets a ggod charge every few days? 10 years?...more? Just curious.

    15 years, maybe more. It's guesswork to a degree, because they just haven't been around long enough in sufficient numbers.

    And if I ever keep a watch for fifteen years I'll be pleasantly surprised.
    I used to list my watches here until I realised it ruined people's Google searches...

    15 years would be great. For the $$$ I had to shell out to get the MB Frog, I would hope it would last that long

    Thanks for the help

    Citizen claim their solar cells should last forty years.

    I'm not sure anyone really knows. As Tribe points out there probably haven't been sufficient batteries out there for a sufficient number of years.

    Just anecdotally, I have any number of Raysman and Gulfman models from the mid to late 90s. Many were boxed for long periods yet all continue to hold a charge quite well.

    Interesting Link! :thanks for that. Because I was wondering too how long they last.

    You got a bad watch. More to the point, you got a bad model. The GW-300, along with some other older models, are known for these failures. I have 3 GW-300's, two of which suffer from the same problem.
