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

Purchased it as a replacement for my Philips Hue switch battery which was dead. No Complaints!

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.

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.

Our security system uses these batteries in the door or window sensors so if a battery goes bad we need backup batteries

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.
