Questions & Answers

Hello, what is the expiration date of the batteries?

This is not a marked item

Do you know how long your storage lasts?

90 days, but 3 are under $5 if you buy a pack

There is a 172 on the back of my Sr621sw. Is there any significance to this?

You can ignore it because it might be a manufacturers mark or something, so long as the size and voltage are correct.

Is it possible to store these batteries for a long time?

They are probably not fresh if they are not marked on the package or if they are bulging slightly.

A good value for your money
5/5

It was very fast for the batteries to arrive, so I replaced the battery in my wife's watch, and it is now In terms of battery quality and longevity, we will have to wait and see how long it lasts I may be able to update the review in about a year. Although I bought three batteries, I had two more than I needed, but I have put them aside and I will have them when I next need to replace the batteries. This is a very valuable product.

Replace your old battery with the perfect one
5/5

The Skagen watch has needed a battery several times, so I have taken it to a battery store to get it replaced. Recently, it cost me The staff said they didn't have a jeweler on-site and they did not want to risk breaking the crystal. I went back to the store a few weeks later and they said they didn't have a jeweler on site. My research and order of my own battery led to me doing some research. The first order I placed with Amazon was lost somewhere in the scorched plains of Katy, Texas, but Amazon generously let me reorder, and my second order arrived two days later. A new battery is an exact match based on brand and model for the dead one, and it worked perfectly and fits in my watch perfectly. And I now have two replacement batteries available for $1 each, so I am good to go!.

Great product
5/5

I needed one, but the seller only sells 3 at a time. It would be useless since these things have expiration dates, and we would probably be nearing the end of their useful lives when I would need to replace the batteries again. However, I started my watch right away and powered it up. There is about 3 years left before the license expires since the date of purchase.

I use it in my watch and it works perfectly
5/5

In my watch, it works like I would expect. The watch ran a bit fast at first, so I thought it had something to do with it, but after speaking with my jeweler he said it probably had to do with a higher surface charge than advertised to allow the battery to stay charged longer. According to his prediction, the watch ran on schedule two days later.

The batteries in three cars are dead
3/5

It probably wouldn't have been a good idea to do that. It's probably not worth the money when it's so cheap. A 5 dollar Energizer is all I needed and I purchased it at CVS. The battery seller at Amazon who didn't respond to my son's inquiry should have listened to him, since Amazon does not back this scumbag seller. Only $2 for a lessened learning experience.

Watch batteries can be replaced in a good manner
5/5

A battery in a citizen watch had died and I bought these to replace it. The work has been going very well since about two months ago. I found the price to be very good and the delivery was very fast.

The impression I got was 6 months have passed since the last update
3/5

It lasted two years when it was original. There was a six-month contract on this one. Using 3 batteries together could last me 18 months, but that would require digging around in my pocket and changing.

The batteries for watches are very cheap
5/5

There was nothing wrong with the batteries, but their expiration date was a couple of years out. In the watch, everything works fine.
