    Casio G-Shock Solar Issue (Not Charging)

    I have a Casio G-Shock Model GW700DU (2867) with solar charging etc. and now when left to charge in direct daylight it will charge but the charge does not last for very long out of the daylight.

    Now i am quite technical and have opened the watch up looking for a capacitor etc and found a battery (CR1616) Does this battery have anything to do with the solar charging or is it just responsible for the light etc ?

    Please can anyone shed some light on this issue please.

    Hi Carl, was the watch originally purchased by you? The CR1616 is a non-rechargeable battery if memory serves correct. It's the CTL1616's that are rechargeable.

    In either case a new battery (CR or CTL) should fix you right up.

    Please do further research though and don't base anything on my post. I am new to the G-Shock game and the more knowledgeable of the group will chime in soon enough.

    Regards,
    Paolo

    I don't think it is a good idea to put non-rechargable batteries in a chargable system. Your manual calls for a CTL1616 (page 4).

    Probably not, unless the rechargeable battery (or charging system) is faulty. Fifteen years is a likely minimum for tough solars, with much longer lives being more usual.

    Hi! Carl:

    I don't expect to see a CR battery in a newly purchased solar G. Obviously you are not the first owner of the watch in question. Are you? I have posted a thread long time ago about my G-7300 Tough Solar originally used a CTL battery and now using a CR and I encountered no problem with it.

    Your watch is not charging because the battery in it is not rechargeable and it's the solar cell that's running it. Replace the battery with a new one! It's probably running out. It is evident that a solar G can use non-CTL battery.

    i have exactly the same problem, the battery you see should be a rechargeable panasonic ctl1616 battery. i have replaced mine yet i still have the same battery drain problem. a couple of years ago i had the watch supposedly fixed yet the problem is now worse than ever.
    please keep me posted if you find a fix for this other than returning the watch to casio.
    thanks

    There have been some problems down the years. The GW-300, GW-500 and G-5600 were notable examples. More recent atomic-solars seem to have had few problems.

    Hi.
    I've just had the CTL1616 battery in my G2800 replaced at the local Casio service center. Previously the watch would indicate a full charge after some time in the sun but it doesn't hold its charge. After the battery was replaced it has no problems at all. Btw, the service center gave me a 3 month warranty on the repair as well so if there're issues still with the battery I can go back to them.
    The worse scenario I've ever come across was with a G7302RL. The battery was replaced 3 times and it still didn't work properly! Eventually the problem was attributed to a faulty charging system on the pcb and they replaced that and the battery as well. They only charged me for the cost of one battery though, hehe! And did I mention the 3 month warranty? that came in very useful indeed!
