My Citizen EcoDrive Just Stopped - What Happened?
I hear that question every day mostly from people who use this type of watch for "formal" reasons (they don't wear it to work). Where do they leave it? Most people say in a draw or in the box. Is this you? Most likely, but for some, more likely.

First Citizen claim:
"The Energy Cells featured in our Eco Drive product have a life of 40 years. Even after 20 years it will still maintain 80% of its original charge capacity. It is highly unusual for one of these special cells to fail."
Second Citizen claim:
"Your Eco-Drive needs light to operate correctly. While most types of light will charge your watch, it can take extended periods of time with "normal" lighting. In these circumstances, we recommend charging by exposing your watch to direct sunlight. Sunlight through a window is acceptable but do be aware the glass in your window will refract and minimize light energy coming through so additional charging time may be needed. After fully charging your watch, be sure to do the all reset/0-positioning(some models) and set your watch, otherwise it may continue to operate in an unusual manner. Charging rates vary by model."
Third Citizen claim:
"Eco Drive = Never Needs a Battery"
Most of what Citizen claims is true, but only to a point. Without knowing the exact chemical composition of the Citizen Lithium-Ion battery, I can only give you specific facts on a traditional lithium ion battery.
Fact 1.
A known drawback of the Lithium-ion battery is that its service life is dependent upon it's shelf life. From day one (regardless if it was charged or the number of charge/discharge cycles) a lithium ion battery will decline slowly in power capacity. This means an older lithium-ion battery will not last as long as a new lithium-ion battery, unlike other batteries. As this capacity decreases over time, the time required to charge it also decreases proportionally (you see it everyday with your cellular phones).
Fact 2.
Lithium-ion batteries should not be allowed to fully discharged below their minimum voltage, 2.4 V to 3.0 V per cell. Lithium ion batteries should be kept in a cool dry environment. Aging will increase at high temperatures like in front of a window or directly under a lamp.
Fact 3.
Lithium-ion batteries will rupture, could ignite, or explode when exposed to high temperature environments, for example in an area that is prone to prolonged direct sunlight through a window.
Fact 4.
Our (meaning the human race) battery technology is slowly involving to a better battery, but we are not there yet. Don't believe me? Why does the average cellular phone battery die in 3-5 years? Why are we not driving in electric vehicles. While our batteries are getting better in weight and longer life, it still isn't "there" yet.
So with those facts in hand about a lithium-ion battery, are those claims made by Citizen entirely true? Not exactly. You will need to replace the lithium-ion battery. When? Like I mentioned above, I don't know the exact chemical composition of the Citizen Lithium-Ion battery, so I can only give you ideas... maybe 5 years to 20 years? Yes it is a big difference in time because some people may abuse their ecodrive, and some may not.
If you your eco-drive watch died and you followed step-by-step guidelines outlined in your Operating Instructions Booklet, then contact Citizen directly to send your watch in for repair.
Notes Regarding Recharging your Citizen Ecodrive:
1. Always Make Sure to Recharge Frequently - watch out for long sleeves too! Long sleeves can block light.
2. When you take off your Eco Drive, place it in a bright, cool location as best as possible.
3. Avoid recharging the Eco-Drive in close proximity to an incandescent lamp, halogen lamp, on the dashboard of an automobile or other locations subject to high temperatures.
4. If you have to charge the watch by a lamp, keep the Eco-Drive about 2 feet from the light source to prevent your watch from getting hot.

What is Eco-Drive?
Citizen Eco-Drive watches use the most technically advanced power generating and storage system in the watch manufacturing industry. A Solar panel teamed up with an energy cell is the power source for the Eco-Drive. The Eco-Drive's ability to use light-energy from any source (sun, lamps, table lights etc. etc.) to generate electrical power means your energy supply is limitless and free.
What is a Eco-Drive Solar Panel?
The Eco-Drive watch uses a thin disc of amorphous silicon under the dial to convert light energy into electrical energy through the photovoltaic process. The electrical energy is then stored in a special energy storage cell. The charging is done in a more efficient manner than was ever before thought possible. Because of this newly developed technology, it is now practical to use a wide variety of attractive and colorful dials.
How is Energy Stored?
A special EcoDrive energy storage cell is used to store the electricity from the converted light energy. The quality of the cell precludes it from being affected from the regular charge/discharge cycle as with an ordinary battery. With normal care and exposure to light, the owner can be assured of a lifetime of reliable and trouble free power. As an added benefit to the environment, the energy cell does not contain the chemicals used in ordinary watch batteries.
Eco-Drive Stopped?
Your Eco Drive needs light to operate correctly. Easy as that. No $10.00+ battery charge. Just walk outside.

How often should the Eco Drive be exposed to light?
Depending on model. Every Eco-Drive model enjoys regular exposure to light. It needs it for proper function and charging. If it has stopped operating try giving it light.
Side Note:
Usually the light in your office, or school is insufficient to achieve a full charge from a completely depleted power reserve. Citizen recommends that you use natural outdoor light from the sun, or an incandescent light source 20" from the watch for charging a watch. Not to scare you, your office, or school light is sufficient for keeping your watch continually charged. It's only a depleted power cell that needs the sun light.
The more complications your eco drive has, the more power it will use. The more power being used, the more recharging you will have to do.
Additional Notes:
After a full recharge from a low or no charge state, it will be necessary to perform an all reset and in some cases a 0-positioning. If this is not done, your watch may not operate correctly.
For simple analog models, pull the crown out the time setting position, leave there for 30 seconds, return the crown to the closed position next to the case, then set the time. For other than simple analog models (perpetual calendar, multi-function and specialty pieces), please refer to your instruction manual or the instruction sets on our web site for the all reset and 0-positioning procedures.
