Product Datasheet

Energizer Silver Oxide 377 Battery 3.6 5 7 7
These batteries have staying power I collect watches so require many 377 batteries. I pull the stems on the watches when not in use which saves the usage on each battery. They are easy to install in the watch and I can depend on them to give me a good usage time. I also use these for little mini-clocks. I know I can depend on Energizer and I've been doing that for many years. May 12, 2012
I use only Energizer batteries in my Watch Repair business! I own a watch and clock repair shop, and Energizer Silver Oxide and Lithium cells are all I use. I go through an estimated 100 of the 377 cell in a month's time, and have had virtually no issues with defective cells. Additionally, of all the cells I have seen, Energizer has the best life, and are the least likely to leak once they have gone dead. They are not the cheapest battery on the market, but for the superior value, it is the only one I will use for any application! January 14, 2012
This product is dependable and long-lasting, out-performs other brands. I'm somewhat of a watch-a-holic, having some thirty-five to forty watches. I like to change up my watches often and the only battery I ever use in them is your Energizer battery (not all of them use the 377 but use same brand). I don't have to replace my batteries as often. The only thing that would make it better for me is if this particular battery came in a economy size with a lower price. You have a good product and don't see how you could improve on it.

Needs to be less money or last longer. Seems like I have many items that use these button batteries. The cost is outrageous for how little a time they last. Please provide some bulk purchase opportunities. Also a battery trester for these little guys would be awesome. December 15, 2011
bad battery I bought a 2 pack of the 377 batteries 2 weeks ago. I put one in a watch which is dead now the other one I put in a clock which is still working. I tried switching them and the one that was in the watch does nothing. December 15, 2011
trusted product i only use Energizer batteries in my watches. i tried another brand and found that they either died before there time or ran slow. For a trusted brand i only pick energizer. September 12, 2012

Answer: 
The Energizer 377 battery is a replacement for the SR626SW. As for whether it's sold in New Zealand and in which particular area of New Zealand is difficult to say. The 377 is a fairly popular item here in the US so it's very likely you should be able to find this item at any major retailer who carries Watch/Electronic batteries. The item, of course, can be purchased online as well, but if you are having major difficulty tracking down a 377, please contact our Customer Service line.

Answer: 
The replacement type for the SR521SW watch battery is the Energizer 379 battery. While distribution varies across many retailers by store, you should have some success finding it at a Walgreens near you.

Answer: 
Thank you for this great question, I would be happy to assist you. Regarding the 377 battery, it does have a 5yr shelf life; the 2011 on the packaging is the copywrite date of that package. If you are looking for the use by date you will find a 2 or 3 letter codes on the back of the package, if it is 3 letters the middle initial will be "z" we would have to provide you with the use by date due to those codes. Please contact us at 1-800-383-7323 and we can better assist you with that.

Thank you for taking the time to contact Energizer.
