Sony silver oxide batteries provide an extremely high quality, compact battery for the high performance devices today. Sony also ensure consistent reliability and performance in every cell. While Silver Oxide batteries are known for mainly wrist watches the application usage due to the high energy density and discharge characteristics have given the cells a broad range of application usage.

Batteries worked well.
SVY
They will save you lots of money in the long run rather than using a jeweler to replace batteries!

These are great batteries and very durable.

I purchased two (5) packs at $2.85 each with free shipping. I figured, if the batteries worked at all, how could you go wrong? Well, as soon as I placed the order, it showed that the expected delivered would be 4 to 6 weeks (little did I know that the product was coming from Hong Kong). Not willing to wait that long, I immediately went in to cancel the order. However, I could not cancel becaused the items showed that they were shipped. Now this means that the supplier received the order, processed it and shipped it in less than 3 minutes. WOW!
Now, I am truly annoyed. The batteries arrived in 6 weeks and I did manage to surive the wait.
I used one of the batteries and they seem to work fine. After all is said and done, I guess it's a good deal if you are willing to wait on them.

What can be wrong with a batteries?
I guess an expiration date? Faking real ones for a Chinese fakes?...
Nothing wrong with this product; EXP 2015(not as fresh though),made in Japan(good),real Sony(good).

NOTE:
It took more than 1 month to deliver 1 oz envelope.
After a written complaint to Amazon CS ,It was delivered in 3 days.(Thanks Amazon)
My guess ...seller just don't consider $4 purchase as a profit, so... priority for the faster shipment is not on the list.
One month??? No ship.tracking???
Now it's your decision to order or not.
That's all folks;)

Good side:
Good price
Bad side:
Only works for about three months on my watch. (Normally one new battery is definitely good for 18 months on my watch.)
So I replaced it with another one in the same package. Still just a few months!
Feel frustrated.
I noticed that the expiration date is Oct., 2012. I bought the batteries on Nov. 2011. I don't know if that is the issue. Be aware of the expiration date!

Very good price but that doesn't matter if all the batteries are dead when they arrive and therefore do not work.

Size Name: 5 Pack
Watch batteries are a usually apin to find as it seems that each manufacturer uses a slightly different battery. In the past I've tried looking for some very particular batteries at our local super megastore, but since I had not found them there I turned to Amazon. For these particular batteries I didn't even bother searching locally, and went directly online.

The reviews for these batteries were all over the place, so I don't know what to expect. It took a while for them to arrive (well over a week), but nowhere near some of the worst experiences that some other customers have had. The batteries were easy to install and worked right off the bat. Usually one watch battery would last me a couple of years, so I was just looking for a single replacement battery. However, at the *very* low price for which these are sold ($2.25 as of this writing) getting a pack of five is still a great deal. Don't know how long is their shelf life though, but if it's no shorter than two years, and if each battery doesn't last more than four to five months, I think this is still a good bargain. If I have any additional experiences with these batteries, I'll make sure to update this review.

I would give this 0 stars if I could. The pack I received has a Dec 2016 "use by" date and none of them work. I bought them to use in watches. When I put batteries into two watches, the watches still wouldn't work, I eventually took them to a watch repair shop, thinking something was wrong with the watches. Instead, I was told the watches are fine, but none of the batteries work.
How do batteries not dated to expire in over TWO years not work at all????

Pleased with speed of delivery of order but when I installed the new batteries in two Skagen 233xltmd watches
the power in the batteries was insufficient to move the calender date to the next day when midnight arrived. Both
watches simply stopped at midnight. Using the crown to manually turn the hands past midnight resumed timing
but the following midnight the same thing occurred. Changing batteries again produced identical result.

I don't know what the shelf life is on these but I've bought some that lasted and some that didn't. It took some time to get them but the price was very good so it was worth it.
