    Has the battery life of the DW-5600E changed over the years?

    I am thinking about getting the basic DW-5600E, but I noticed the battery is only rated for 2 years on this model. I've seen tons of anecdotal evidence, however, that points to the battery life for some of the older models (5600C, et al.) being more like 10 years, the same as the new Gulfman and some of the other new G's.
    I realize that Casio gives conservative battery life estimates on purpose, but is there really a difference this big between the efficiency of the new 5600 and that of (for example) the new Gulfman?

    The Gulfman uses a bigger battery than the DW5600E, so that's one reason for the difference. I'm not sure about this, but the type of light used on older models may have made a difference. I think EL backlights use more power than LED's.

    You're absolutely right, triple T. As in many modern companies, I think Casio lawyers have the last word on what to print in the manauls (and how to phrase it) because of legal concerns.

    i have several tough solars i think i wont have to change the battery as offten on those but after watching Sjors battery replacement video i think i will change myself nextime.

    btw i have a dw 5700 that is about 15 years old , bezel just cracked but battery is still working. i dont think i have every replaced it.

    Cheers for the replies guys.
    You're probably right about the battery size, Lexxorcist. Doesn't the Gulfman use an EL backlight too though?
    And Vintage and Jester, I went and ordered one anyway. I figure I can stretch the batteries a good bit anyway, since I probably use the EL about once a week, if that
    I'll have to see which watch out of the G-2300 I have, or the 5600, looks more 'grown up.' I'm finding the red lettering and the zulu on the 2300 makes it look a little childish, but I don't really want to fork out $30 for a strap for the 2300, because I can order a 5600 for that price
    I'm also thinking the low profile of the 5600 will probably make it a keeper for me, as I've found that in a lot of cases, toughness isn't necessarily measured by how much abuse a watch can take, but by whether it gets caught or reefed around by things in the first place (case in point: my W-71).
    Anyway, I'll let you all know what I think of the 5600 when it arrives. As if you needed another 5600 review, haha.

    Yes it does, I think all recent G-Shocks do. The bigger battery will be the main reason for the longer battery life compared to the DW5600. What I found strange though, was the difference between the battery life estimates of the Gulfman and the Mudman, which both use the same CR2025 battery. It's 7 years for the Gulfman and 3 for the Mudman. The only thing I can see to explain this big difference is the Gulfman's EL light stays on for a shorter period.

    Re: Has the battery life of the DW-5600E changed over the years?

    @ TTT: the resin band for the G-2300-9V is only $9.50 direct from Casio USA (1-800-223-2001) 9:00am - 5:00pm eastern time Monday - Friday. Part # is 10001449, and currently it's backordered (3-5 week wait). edit: I just reread your post...I didn't think of asking for the part # and price for the cloth band...doh!

    And I think they're just being very conservative with the estimate. I believe the EL is actually more efficient than the old lights. The old lights were actual bulbs and I believe the EL's actually draw less power than the old bulbs.

    @Lex: that's interesting. I think in that case, Casio is assuming you're using the longer EL setting, becuase in the Mudman, the EL time can be adjusted.

    The EL time can be adjusted on both models, but the Mudman's stays on longer on both settings. Other than the dual stopwatch (which I can't see using that much power), this seems the only explanation for the estimated 4 years difference.

    I can't say I know for sure if the little LED bulbs use less than the new EL lights, but I read that on here somewhere. One for the experts I guess. It does seem that the estimated battery life dropped around the time of EL's being introduced though (in '94 I think).

    Ah, maybe I have the lighting idea backwards then. But, I do know it wasn't a small LED. It was an actual mini-light bulb. I just saw Sjors post about that somewhere...

    edit: and yeah, there's no way a dual STW could make that much difference. I wonder how they got it so different...maybe different lawyers .

    I would also imagine a bulb using more than EL backlight for some reason (probably because it's more recent technology) but I really don't know. EL's do have a reputation for being power hungry.

    With the G-9000 and G-9100 being released around the same time, you'd think the estimates were calculated using the same reasoning. I don't know if you have both, but on the short EL setting, the Mudman lasts about as long as the Gulfman on the long setting. I can see this making quite a difference as they both have the 'dual illuminator' so there's 2 seperate EL lights working together in these models. It looks great, but the poor battery probably doesn't like it much.
