Can an Energizer 1616 be used as a replacement for a CTL 1616

Please don't type in all CAPS, it is considered SHOUTING and harder to read.

CR2025 is the battery type!

I have the same watch with the same issue, .. I don't want to have to junk a good watch, .. hope someone can help.

The CTL 1616 is a special device.
It's not really a battery, but a "capacitor", which means, that it's mainly supplied by the energy of the light. The capacitor is designed to maintain the functions only for (short) periods of darkness.
It's NOT a "standard lithium battery", because It has a different voltage (2.3 V instead of 3 V) and consists of different materials.
Unfortunately, the capacitor loses its ability to store the energy over the time. So your watch may be able to maintain all the functions for more than 11 months of darkness in the BEGINNING, but after a few years it may only last for a few hours!
However this may be STRONGLY influenced by the use of the functions: for example the automatic reception of radio signals or using a digital compass may strain the energy seriously.
So, the use of different functions may affect the lifetime of a CTL 1616.
I also recommend to expose the watch to (bright) light as often as possible in order to maintain a HIGH level of stored energy.
I also heared that there were serious problems with the quality of this type of capacitor a few years ago. Maybe a new CTL 1616 will last for decades.

Just need a small phillips head screwdriver and a CR1616 battery.

Do you know how to toggle between am/pm and military time? If you do, please email me at fischermh at netzero.com

The battery is CTL 1616 and I had the same occurance when I opened up my model Casio model 3043. I needed to use the battery to test my model 2767 and find out if a new battery would bring it back to life (yes, it still lives). After replacing the battey back into my 3043, I jumped the (ac) to (-) and at first the watch would indicate all was well but then it would revert back to "open". I tried over and over to try and get the "open" display to clear but I was not successful. I then thought to go ahead and replace the back on the case to see if the three contact springs would change the display and sure enough, "open" no longer was in the display. The watch works perfectly as before. As for the 2767, as soon as I jumped the (ac) to (-) the "open" display went away. There is only one spring contact to the back case on the 2767 model. Unfortunately I do have an extra spring that fell out when I opened it up and I have no clue as to where it goes. I have not found anyone who can help me on the location for the shorter spring. Any advice would be most helpful.

I found one of these on ebay. Here's the item I ordered.

I used the instructions here to replace the battery myself:

Hope this helps.

CTL is the designation for a rechargeable secondary battery. The CR is a primary disposable battery and is a 3 volt cell. 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.

Send it into repairs and they will send you an estimate on what it would cost to fix it. Give them a call at 800-706-2534 option 2.
