My experience is using these for watch batteries. All of the major brands seem to be of high quality. pick the latest date and cheapest price. I've never had a bad battery from Maxell, Sony ( Murata)or Renata. Beware listings for really cheap brands. They often say they are silver oxide but turn out to be alkaline (inferior and short lived). Forget the listing, watch (pun intended) the actual package picture and fine print. The silver oxide are the ones to buy They are more expensive than alkaline but unless you enjoy changing your watch battery ( most common use) yourself if you have the tools and skill then stick with silver oxide. I have found that Maxell seem to be slightly cheaper and Renata the most expensive, but your shopping experience may vary. I have found no difference in quality. These things do seem to last longer than the package date but do expire eventually. Read full review

A five-pack of batteries for half the price of having one installed? That's a pretty much unbeatable deal—provided you know how to safely open the back of your watch. That said, I still don't understand why they're identified as 'Sony' when the only brand name that appears on the packaging is Murata.

This is old Sony brand batteries. Very pleased with its quality and price. Hope more consumers will become more familiar with this formerly known as “Sony”brand.

As I have had these batteries in just 1 month it is not easy to say it is excellent, but Sony is a great brand in general and worth using in your watches or another small electronic units. I am sure the battery will last for at least 1 year, typical 2 years, and in some cases longer. For this price I can accept changing batteries every 2nd year. :-)

Best Battery ever. Worked perfectly in my watch and it is keeping great time. It comes in a wonderful silver color, very attractive. I'd certainly buy again but since I bought 5 and each is good for about a year, it will take some time before i need them.

The envelope came in well before the expected date. When I ordered it was for a small ornamental clock. On a whim I checked a watch of mine and one of my wife's, and they both used the same battery...bonus!!

They came quickly, worked perfectly in a watch that has been sitting in my drawer for 20 years, put the battery in the watch is still working. I did not want to buy a lot of batteries, so just buying 3 was a great deal, saved me a trip to Walmart, and it was a great price.

I've always found it a hassle to replace a watch battery. I have been scared to change it myself for some reason. I usually just go ahead and purchase a new watch. Now, I have a pile of watches that I never took in to have a professional change the battery. So, when I saw what a great price they were, and with a respected brand like Sony, I jumped on it. I'm glad I did. I changed all of my batteries and have an extra. I recommend other people with a pile of watches do the same and change the battery themselves and wear the watches they have instead of letting them pile up.

Bought a multi pack as these watch batteries just don't seem to last very long anymore. So far so good with these. Have only used one and hopefully won't have to replace it for a couple years.

Arrived on time and is an excellent value. Two batteries for about 2 dollars is a steal. Local watch shop wants $7 to chance battery. Did it myself for 1$.
