Review: It's the perfect replacement rechargable battery for my old G-Shock GW-M850 - I got this for a Casio G-Shock GW-M850 that is now around 13 years old, it works perfectly appeared to be fully charged already after I installed it, the CTL1616F was and is the exact same battery/capacitor that came out of the watch. The only reason I had to get this is that I think I cooked the original battery by leaving the watch unused at the window for a long time the watch probably overheated and ruined the battery, apart from that the original battery had worked perfectly for the 13 years I've owned this watch so the new one should work at least that long or longer. The symptom was that although the watch still worked and the power indicator was still at H (full) any time I used the backlight the L M H indicator would start flashing and the backlight basically didn't work any more. After replacing with this new capacitor/battery the watch is working perfectly again and the backlight is great. Just make sure that if your watch is a solar powered watch that you get the Panasonic CTL1616F this Casio item is the Panasonic CTL1616F it's the F that's important. Pictures show the watch with the new supplied battery, my backlight now working and the old battery which I removed from the watch the new one was identical to the old one. The last picture is the watch case being opened I would recommend that you get a new seal is you are doing this with a G-Shock as you'll probably forget at some point that you've opened it up and your 200m water resist will not longer be valid I cleaned all the years of sweat and gunk from mine and from the strap as well as replacing the gasket and hopefully my watch is still good for its 200m water resistance. The Casio part number for the gasket is product code: 10237046 if anyone has a similar model, the o-ring fits multiple G-Shock models.
Review: Perfect fit for my Casio ProTrek PRW-1500 - After more than ten years, the battery in my Casio ProTrek PRW-1500 solar powered watch was not charging as it should and not giving enough power to provide full functionality despite showing an H [High] symbol. After much research I found this was the required battery and made the purchase. You will need a few special tools to get into the watch and perform the change [small cross-head screwdriver (to open/remove back plate), a pin (to release battery clip), plastic tweezers (to handle battery), needlepoint metal tweezers (to reset after battery change)], but the procedure is fairly straightforward, if but a little fiddly. N.B. Be careful not to remove or lose the tiny springs that are in the body of the watch, nor of course the screws you have removed. After battery replacement, ensure body of watch is seated well and that the spring loaded buttons are in position. One may need to gently prise back the spring on the body to get it to sit in the correct position behind the button. After changing the battery, resetting and replacing the back there is an unnerving wait as the watch appears, at first, to be non functioning. The C [Charging only] flashes and the time begins at 12:00 on 1/1/2008. However after a few minutes in bright sunlight, it was soon showing an M [Medium charge] whereupon one can go ahead and adjust the watch to the correct time, recalibrate the altimeter, compass etc. The R/C [radio-control] time reception kicked-in automatically soon thereafter but failed to set the watch to the correct time, but overnight did finally update. While there are a few LCD elements that have partially failed after 12 years, there's still some life in this watch yet. And for £11 to restore its full functionality for another few years, this was definitely a worthwhile purchase. After all, a new equivalent Casio ProTrek can cost in the region of £300+. So all in all a good product and reasonably priced. But perhaps only for individuals adept at repairing fiddly, small and tricky items.

## Questions & Answers

**Q: Is this suitable  for  g  shock  awg-m100**
A: No, I do have an AWG-M100 model watch but this battery was bought for another Casio I have. The AWG-M100 battery is a re-chargeable one I believe

**Q: Hi, is this battery (ctl1616f) the rechargeable version?**
A: Yes. This is the battery used in many Casio solar powered watches. Although they look similar to other disk batteries the internal chemistry is very different. These batteries are designed to supply low power demands but can be recharged by a small solar cell for a minimum of ten years. They can last much longer in regular use, i.e. kept charged. If used to replace a Casio watch battery, it will may take a few hours or days of exposure to full sunlight to bring the battery up to a full charge on the watch indicator, if fitted. This is perfectly normal and not a sign of a faulty battery. Once fully charged the battery will run a solar powered watch for around 9 months, or up to 2 years in power saving mode without further exposure to light. Of course, the battery can be recharged even if it does run flat. These batteries have a very exotic chemistry which is reflected in the price. As far as I am aware, Panasonic are the only manufacturers, so there is no other alternative supplier. The last watch battery I replaced lasted 14 years before it started running out of power during the long winter months. On that basis the batteries are reasonable value for money.

**Q: is this battery made in Japan or Indonesia? Thanks in advance**
A: The battery I bought was made in Indonesia.
