Customer Ratings & Reviews

Energizer has built a reputation for reliability, and the 2450 continues that tradition. It has already outlasted competitors, providing great value for the price. The price was a little high but I have been pleasantly surprised by their performance

Always want to keep a few of these handy. They work great for their intended purpose and price right. The battery life is good and Energizer is a reliable brand.

I had to replace the battery in my Nixon Baja Watch and when I opened it up, the watch had a 2450 style battery. Bought it from Best Buy and had the battery changed in all of twenty minutes.

MY GO TO BRAND FOR BATTERIES. ALWAYS LAST LONGER THAN THE OTHER BRANDS

Good product. The two pack is nice because it allows you to replace batteries in both key fobs.

It great to know that when my key-fob battery dies I can find this awesome top quality battery at any BestBuy. This happened to me while traveling. Buying online was not an option.

By far the greatest batteries I've ever used! I felt like I had the power of Zeus flowing through my veins when I opened the package! As soon as I plugged them into my lantern, I heard electricity sparkle and a light as bright as a thousand suns beamed out and now I have complaints from my neighbors about my "flood lamps" blinding their chihuahua, it was just a small portable Mumei lantern! But yeah these batteries are great. I only used 1 and I can already tell I'll be just as satisifed when I use the second.

They fit perfectly in my car's key fob, as expected. Of all the batteries I've bought, they worked just like the others, which makes me glad since dysfunctional batteries would have put a serious damper on unlocking my car. I am happy to report that these batteries provide power; a fact that allows them to be called batteries. I would buy them again, given they are the required option for fixing the devices which call for them. They are perfect in almost every way a battery can be perfect; i.e., it functions as a battery for the device that calls for it. They are imperfect in that I do not expect to be able to use them for any other function. I do not recommend getting batteries that fill other functions, too, however, for they tend to not be batteries. So yes, my single function batteries are as expected--working batteries. Which is about exactly as good as a battery gets.

Great battery life never have issues with this product.

Perfect replacement battery for my Toyota key fob. It works great. I was created by an associate who helped me locate the battery that I needed. Excellant customer service.

Batteries worked very well. The watch that they were purchased for started working immediately.

You need battery and best buy have them all never had an issue when i get it from best buy

Bestbuy has priced this decently for small quantity. Lot of online stores sell bulk for cheaper price but either they are sub-quality or the expiry date on the battery is very near. Purchased this because of Energizer brand and that Bestbuy will carry a genuine and not fake unlike some online retailers.

Battery of choice for all my Samsung SmartThings devices which keep me and my family safe at home. Usually about 9-18mon life depending on device and frequency of use

Just the right size. It fit our remote exactly and kept us in business for another cycle.

Perfect for what I needed. Long lasting. Haven't needed to replace them yet

Got these to replace the battery in my key fob. Works good other then now my passenger side door won’t lock or unlock with any of the other doors.

Exactly what I needed to fix my key fob. Easy to find in store!

Energizer is a name you can trust. I purchased these batteries for my 2022 Honda Key Fob. I am confident that these batteries will last for a long time.
