I purchased the Energizer 379 battery to replace the Renata 379 battery that was originally installed by the watch manufacturer in two of my daughter's Fossil watches (model numbers ES-9525 and ES-1001). I also replaced the Energizer 379 battery (I do not think Energizer was initially installed by the manufacturer) in my daughter's Relic model number ZR33503 watch with a fresh Energizer 379 battery. The energizer battery has a three (3) year shelf life based on the date of manufacturer. The two-position manufacturer date (usually alpha characters) is printed on the packaging. You can call Energizer Customer Service at 800-383-7323, M-F, 7:00AM-6:OOPM CST and they will give you the month and year the battery was manufactured based on the two-position code you give them. For example, code "JC" meant the batteries I received in January 2011 were manufactured in October 2010. Manufacturer Codes are randomly assigned so you must call Energizer for the battery manufacture date. Tip: To preserve battery life, disengage the battery by pulling out the watch stem when watch is not in use. NOTE for Fossil watch owners: After speaking with a Fossil watch service center, I decided to replace the battery in my daughter's Fossil watches rather than paying $10.00 to have a service center do it. Granted, it may void the warranty. And, the back cover gasket may not seal/re-seal as well as it would if the Fossil service center were to perform the task, but I feel it will seal well enough to provide many more years of satisfactory service. Keep the "original" battery and re-install it in the watch if you must send it to Fossil for warranty repair. There are some Fossil watches such model number ES-9825 that you can not easily remove the back cover and battery replacement must be performed by a Fossil service center. Energizer 379 Button Cell Silver Oxide Sr521sw Watch Battery (1 Pack of 5 Batteries)
I bought these for a few very small watches i had. They came perfectly packaged and intact. I also used them as a replacement for the thinner SR516SW. So far, it seems to be working. The package discount makes it very worth the value too.
First time buyer for online watch batteries. Product arrived just as described! 5 Batteries (priced 0.78 cents per battery) you can't beat that price anywhere. We used it for a guess wrist watch and no problems. 4 more batteries for spares =]
I did get 5 batteries and got it fast. Used one and it was working just fine. Would have given them 5 stars except you don't really get what is pictured. You do get 5 batteries but it's part of a larger packaging. Imagine cutting the pictured item on Amazon up into five and selling them piece by piece. That's what you'll get. Packaging and battery looks like the real deal though. Can't beat the price! - Battery - Great Price - Watch Battery'
