I went to many stores, from Sharper Image to Best Buy to Circuit City to Radio Shack and a few online spots to find the CR2025 batteries for my clock radio remote and air conditioner remote. The stores either did not carry the exact battery type or wanted over $6 per battery. When I checked Amazon, the Energizer battery ECR2025 was available for less than $4 for two. I was concerned if ECR2025 was the same as CR2025; I took a chance, and they turned out to be the same, so the E probably just stands for Energizer. The batteries have been working fine because the remotes work fine. This was the best deal for this battery. Delivery was free because I bought the batteries along with something else from Amazon. Amazon seems to carry many things with excellent prices, and the free delivery is great.

The above review was from a late 2007 purchase, which is now outdated. One of the two batteries I bought finally stopped working (Energizer ECR2025 lasted 6.5 years), so I came back to find it again. However, I noticed that the product has since changed on the website, and Amazon is no longer the seller. Instead the new page sells various batteries instead of just the one I bought. The new reviews are no longer "Verified Purchases" (which often means they are fake reviews if not "verified"), so I would be careful to check each retailer before you buy a battery here. Read the individual reviews of the retailer (by clicking on the retailer's name) instead of the product page of Amazon. Look for companies with 98-100% positive 5 star ratings only. Otherwise, you may find yourself buying old/used batteries. You should also do a general search on Amazon for your battery to see if other product pages will offer you cheaper prices and better quality retailers. Again, also check retailer reviews instead of just the product reviews (and always check if a product review is "Verified Purchase" next to the reviewer name to make sure it is a REAL review).

A battery either works, or it doesn't. These work fine, and they've been working for over a month since I received them. The non-Amazon dealer sent them fast, in their original Energizer packaging, with a far-distant expiration date.

I've been using these in one of those counter-irritant conductor devices that zaps you with electronic jolts to reduce or eliminate temporarily what ails you. I've tried several other 2025s, but the Energizer is definitely stronger and longer lasting. This price represents a 33% reduction compared to Walgreen's.

I definitely read the reviews on the items I view on here so decided to leave one too.

Some reviewers mentioned receiving old stock batteries and that some just didn't work. I went ahead and ordered this battery, hoping to avoid having to buy a new digital watch, which I only wear rarely. Well, to get straight to the point, it works! My watch works along with the illumination feature so I am happy spending what I did for this battery than buying another watch that was around $20.

Hope this helped you out!

Sure these batteries are good. They last about three years in my alarm remote. I get them through Amazon's free shipping offer when I have $25 or more worth of purchases. The box store charges 5 bucks a piece for these (if you can find them) and Amazon charges less then half. Kind of a no-brainer to me.

I recently bought a sound system from Amazon, but the battery in the remote was out by the time I received it in the mail. Not only was I credited $5.00 for that dead battery (after a couple simple emails to the seller), but I was able to buy this replacement at a fraction of the cost with Amazon Student (or Amazon Prime), and I also got it in the mail within two days. I also checked other local electronics stores, and they were asking several dollars more for this small piece of metal to power my remote, which I found quite ridiculous. And, these smaller, more specialized batteries are extremely difficult to find, and only smaller electronics stores even consider carrying them.

Energizer is also known for their long-lasting batteries, and having such a top-name brand battery in my possession with some extra change in my pocket makes this college student a happy student!

This battery is just great. I ordered one for my HP laptop's remote controller. I would rate this battery A+++++, would buy it again. Although it has not shipped yet, so I am not sure on the quality, I can guarantee this is the battery you need for your HP Pavilion entertainment PC dv6915nr with Altec Lansing speakers. I know , because I did the hard ground-level research, opening the controller, finding the battery, removing the battery, examining the battery, finding the name of the battery, replacing the battery, closing the battery containment area, and so on.

We've bought batteries from this company before. The card it came sealed in was printed in 2011 -- but since Energizer batteries are good for many years that is not a problem. The important part, it works and the one of a kind little desk clock that I bought in Taiwan over 10 years ago works again -- all for a price that is at least 1/3 of what I would have paid locally. Great dealer that ships fast.

Easier than going to the store, works just as well, shipped fast, and costs exactly the same. So glad these are available online - they have been out of stock in the store forever and would cost twice as much if we let them order us one. Perfect that there is a single package too, because the little device this is used in only needs one and has only had the battery changed once in it's four year life.

I happen to have one of those heart rate monitors that regularly eats batteries, so I am glad I ordered these, because they last about a month, which is terrific. The other "regular" (not extended like these) batteries pooped out in a couple of weeks. It sounds sad, but I'm thrilled about the fact that I'm only changing a battery every month. Great product at a great price.
