    Solar G-Shocks question.

    Solar G-shocks watches have rechargeable batteries, my question is; won't these batteries eventually wear out? I would think the batteries won't last forever and will have the be replaced at some point or they won't store their charge as well over time like NiMH batteries. Either that or the solar panel will wear out.

    Hmmm... from what I read in this forum, the Batteries are the ones who fail.
    Now, i don't know if these dead batteries can be replaced by a new one [although i hope they can be].
    As for the Solar panels, I haven't encountered a broken solar panel in Gs.
    I am worth more than any item in my watch box.

    Re: Solar G-Shocks question.

    Was curious about this exact topic last week. Here is the thread I found... I'd say no worries. Looks like the cells might outlast most people's interest in the watch.

    Rechargeable batteries will wear out, but panels and displays will probably outlast other vulnerable parts and possibly the owner.

    The life of the display may be a bit academic. The majority of solar watches will be thrown away after the first component failure, whether or not they are repairable. Equally, most resin G-Shocks will be thrown away when the resin rots.

    At 53 I'm getting ever more confident that my watches will last as long as I do.
    I used to list my watches here until I realised it ruined people's Google searches...

    Re: Solar G-Shocks question.

    Speaking from my experience:
    Frogman with a ML-battery. Has been accompanying me for around 6 years and was maybe 1 more year in the store.
    No battery failure or any other problems encountered until now.

    Regarding the solar panels- I am far related to a project developing such panels and the life expectancy is - lets put it that way- looooooooooooooooooong.

    I think li-ion rechargeable batteries have cycles in the thousands, before they start losing efficiency (where when full they only hold 85% as when new). I'd expect the batteries to last more than 10 years. There are Raysmen (the first solar powered G) going on 10-11 years, with the same battery, and they work fine.

    The newer battery is a different design, but being newer (and ignoring the few seemingly bad ones in a batch) should last just as long.
