Please before you order compare our image with your existing power cell; the MT920 power cell has 12 versions and they are not interchangeable. Each MT920 is designed for a specific time piece and caliber or movement. Only order after you compare and diligently verify this is the correct version of the MT920 your time piece requires. We do not accept returns on opened product which are non-resaleable after being opened and handled.

Factory tested fresh new factory sealed product; No returns accepted for any reason.

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 nitrle or non-powered gloves. 30 day warranty. Big box and kiosk employees ruin these then say product was bad. Do not take to them for replacement; do it yourself for a job well done. If you use a watch repair shop and they mishandle the capacitor and ruin it then say it is bad we will not warranty it.

Please note that the MT920 is the basic battery or capacitor engine for 5 different configurations; look at all the search results for the MT920 and eyeball match to verify and confirm if you have any doubts. The Panasonic MT920 is a button-type titanium carbon lithium rechargeable Li-ion battery that uses lithium titanium oxide as the positive material, carbon as the negative material, and organic electrolyte.
