Re: Casio GW300 (2608) battery replacement

Hey all. The charge provided by the solar cells on the watch only really extend the life of the battery. The total run time of a battery depends on how the watch is used... backlight requirements etc. The battery will be depleted and need to be replaced.

Here is a site that has good instructions on how to change the battery in your G-Shock watch.

If you want to ensure you still have a the same water resistance rating, I do suggest that you take it to a watch guy to have it replaced for you. They clean switch contacts also and you keep water resistance rating. Good Luck and vote this as a "FixYa". Cheers

Re: Casio GW300 (2608) battery replacement

Can't live in the dark all the time. I found that I need to keep an eye on the charge level bars and at times even put the watch into sunlight (off the wrist) to charge up. Had mine for about 5 years now and am aware that eventually the battery will need replacing. Still strokin' along tho once I figured out that especially in the winter months I've gotta keep an eye on charge level.

My Casio Gw-300 G- Shock watch face intermittently goes blank altogether. Immediately prior, the solar battery shows a full charge, (in addition, the back-light battery is less than a year old). When the...

From your description the solar cell charges the battery and keeps it topped up. I think the rechargeable battery is the problem because when the screen goes blank the battery level drops to low and the LCD blanks out which would explain the intermittent operation of the watch. I think it is worth getting it checked out with an estimate.

You likely have a dead battery. Follow the instructions on this web site
it is clear and covers most casio models. Watch closely for the springs when taking your watch apart. You can order the battery online (the best option) but most people that use a standard lithium battery seem to have no problem.

Casio g-shock protection model blank face after new battery installed by a jeweler

What kind of battery did they put in it?? G shocks are powered by a rechargeable solar battery!!! Should not have been replaced unless it was the same type of battery. I would be going back to jeweler and asking them to send your watch to Casio and they pay for the new solar battery. Let me know what happens.

How do I replace the battery

mcdevito75 here, This can be very, very tricky on a Casio watch, Casio"s have an LCD liquid crystal Diode in the face and any un-do pressure on the face will break it. Best Bet, look for a small watch repair shop in your area to change the battery, a small shop will save you some money on the cost.

The CTL1616 while the same size as the CR1616 function completely differently and are not interchangeable. The CTL1616 is 2.3 volts and is recharged by solar or light or kinetic movement. The CR1616 is 3 volts is not rechargeable and will not function properly in a time piece designed for a 2.3 volt circuit. There is only one manufacturer of the CTL1616, Panasonic and they sell through Casio parts distribution.

On the solar charge watches, they use a chargeable Lithium battery. It is NOT an off the shelf regular battery! It is best to send the watch to the factory service rep in your area for a battery change.

In many of these models the battery is using solder contacts to the circuit board. The person changing the battery will require the original spec battery, and be equiped to do surface type soldering.

When working on this watch, the factory service will change the seals and do a pressure water resistance test. The regular corner watch service store is not equiped to do this type of testing.

Normaly, the battery in solar watches should last more than 5 years. Some are going past 10 years!

Like anon129 I had the same problem. Those "outdoor" functions need more battery power than just telling the time and the stopwatch do. When the rechargeable lithium battery gets old and tired - which they apparently sometimes do for no very good reason - it can't provide enough power when required to, so it goes into recovery mode. It's very annoying but if your battery level indicator is already showing H the only solution is to replace the battery.
My second battery seems to be lasting better, but I'm not leaving it charging in the sun for ages this time, as I think it overheats it when the battery is full. I'm also not using the outdoor features as much, and the light hardly at all.
