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.

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!

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;)

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

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????

I installed two batteries in my watch and neither one worked. I then installed an Energizer batterie and it worked fine. Never going to buy a Sony batterie again.

I replaced the battery in my Dad's watch and it started working. I guess there is nothing more to report other than that the battery works. I cannot say for how long because it's been just one week since I used the first one.

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.
