Factory Sealed Genuine Citizen Capacitor 295-33
Please note that the MT621 is the size number; These capacitors resemble a battery but their function is very different. The capacitors on the kinetic oscillator watches recharges by body movement while the capacitors on the solar cell watches are powered by all sources of light.
Capacitors are storage devices and do not always come already charged. The customer needs to charge the watch after inserting the capacitor. They should not be tested , a battery tester will not give an accurate reading. Most of the time, the capacitor itself is not defective. Sometimes the connections may not be attached perfectly and may be the problem.
Please do not use a battery tester or volt ohm meter as these very low volt cells can be ruined by testing. Please do not handle with your fingers as static electricity, body oil and contaminants can ruin the cell. Please only handle with plastic tweezers or wear non-powered gloves.
