Casio CTL920 in our DIY Kit with tools

The power cell in the above Casio CTL920 package is the Panasonic CTL-920F (aka X14547) in our DIY Kit with tools

Used in many Casio and some Citizen timepieces

The Panasonic CTL920 is a button-type Cobalt Titanium Lithium (CTL) battery that uses lithium titanium oxide as the positive material, carbon as the negative material, and organic electrolyte. Sometimes Panasonic will insert a "A" or "F" i.e. "CTL920F" for their internal use and is the exactly same as CTL920.

We sell genuine fresh Japan design (secondary) rechargeable watch batteries (also known as capacitors) and regular Japan (primary) silver oxide watch batteries for Japan timepieces. We do not sell alkaline batteries for any timepiece due to the poor performance of alkaline chemistry.

OUR Do It Yourself KITS containing these user replaceable genuine Citizen factory capacitors can save you some serious time and money. These are fresh sealed factory tested products. Some timepieces will have the second hand skip to indicate low battery level and this is a reminder to replace the power cell. We have thousands of successful and happy DIY customers that have replaced their power cell. If your watch does not work it may be a problem that cannot be solved by replacing the power cell. Make sure of this before you order anything.

Use this to clean the watch when you open it Battery Saver

Your other option is to return the watch to the factory for an expert tune-up and we recommend this if you dont mind the expense because they will fully clean and pressure test (if necessary), put new seals and a new capacitor and guarantee their work. They may not give a price over the phone and ask you to send it with a prepaid return. This is fair because they have to evaluate the condition in order to price-out the solution.

Our solution is low cost and fast and is for those who have watched the YouTube videos and are confident of a DIY solution. We do not recommend using a store or kiosk because of their inexperience. Either do it yourself or return to the factory for a trusted tune-up; dont be otherwise sorry with an expensive botched job or incompetence.

Please before you order compare our image with your existing power cell; the CTL920 power cell has many Citizen versions which are not interchangeable. Each CTL920 Citizen version is designed for a specific timepiece and caliber or watch movement. Only order after you compare and diligently verify youve selected the correct Citizen version of the CTL920 your timepiece requires. This is easy to do. We do not accept returns on opened product which are non-resaleable after being opened and handled.

Please do not use a battery tester or volt ohm meter as these cells may be ruined by testing and they may not indicate the normal voltage of a regular 1.55v disposable watch battery. Please do not handle with your fingers as static electricity, body oil and contaminants may damage the cell. Please only handle with supplied anti-static tweezers and finger cots.

If you use a shop or kiosk they probably have never been trained or even seen a rechargeable watch battery, these are not the folks to work with. Ask if they know how to replace a rechargeable watch battery! They often will install as a replacement a regular 1.55v cell replacement which could harm your watch. Make sure you get the original power cell returned to you in a plastic bag or envelope and you mark the date on it. Follow this same procedure for rechargeable coin cells some watches use and we also sell these.

Please note that the CTL920 is the basic battery or capacitor engine for many different configurations; look at all the search results for the CTL920 and eyeball match to verify and confirm if you have any doubts. Why waste money taking your watch to a shop when you can do it yourself. These capacitors may resemble a battery but their function is very different.
