Rated 5 out of 5 by from Long Lasting I love how long these have lasted in the toys that I have used them in. I also used some in an item that gets left outside a lot and with previous brands have ended up having to clean up the mess from leaking batteries. So far these have been in the item and I have had no leaks! I plan on picking up some more of these now that Hurricane season is close, just to have on hand!

Rated 4 out of 5 by from They work! I received these batteries to review. They are ok. I personally have used better, But these work well too. I'd love for them to work longer than 2 weeks though lol. But 2 weeks is great in xbox remotes. Great product and works.

Rated 5 out of 5 by from best batteries ever okay so my daughter is in college and took her WiiU, which really burns through batteries like no bodys buisness. I have to say she still has the same pack of batteries and her controllers seem to be lasting twice as long now. I have since bought another pack to use for the game systems we have at home and i too was amazed at how long they lasted. these are very good long lasting batteries in my opinion

Rated 5 out of 5 by from Long lasting! I used the Fusion AA batteries by Rayovac in a digital camera of mine that runs through batteries like crazy! I am happy to say that i was able to take the pictures i wanted and did not have to change out my batteries. It was quite impressive life, better than the other leading brands of batteries. I think i will be purchasing these instead for now on! I am very happy and pleased that i had this opportunity to test and review for free in the exchange of my honest and unbiased opinions and review.

Rated 5 out of 5 by from New FUSION batteries These Rayovac Fusion batteries are AAs, like other AAs, but last longer. I tried them in a flashlight and they kept on working. It's hard to quantify, but they seemed to be longer lasting than my usual "replacement cycle."

Rated 5 out of 5 by from Long lasting power When I received these batteries I decided it was best to test them in something I used a few times a day. So I went with my electrical toothbrush so I could properly test the promised longer lasting power of these batteries. Normally, my toothbrush goes dead in a month or so. It has been over a month and my toothbrush almost has as much power as the day I put these batteries in. I say almost because it is possible to tell due to how loud the toothbrush sounds and how fast the rotating heads turn. So I suggest you all try these batteries in your battery operated items and form an opinion yourselves on their long lasting power.

Rated 5 out of 5 by from Consider Overall Value I tried the Fusion Gamer 6 pack of AA Alkaline batteries also. This particular “Advanced Alkaline” was sent specifically to test by the Brand and suited my personal products for long term use. I will be specific about a situation you do not want. I placed the Fusion Gamer (blue package) in an iHome charging speaker radio and the electric cord detached by accident. The battery drained down, as it was connected to something and therefore in charging mode. Even though this Fusion (red package) is another longer lasting type, the same type of situation can happen. I was able to transfer them over to a less demanding beauty rotating cleansing device and a massaging arm band, which I also tried for use with this type. To check the level of sound or power with the iHome- I connected a small simple old mp3 player and the new Amazon Fire tablet, but this time watched and observed for a short time with this tester. It is too soon to tell how long it will be equal to using electricity in this manner for music listening. I also want these to be around for my Brother Label maker which does not have a power cord. It happens to be a high battery user or "Power Hungry" especially left in or working with it on. I do not have enough rechargeable batteries around to power it. In emergencies and electricity outages, or just inadequate places to charge those types, this option becomes necessary. Because batteries need the same capacity level and an 8 count often fulfills most needs, it is realistic to have them on hand. Unless, I drained both battery types and other brands the same way, it would be difficult to fully compare some qualities in a short time. I have been familiar with the Brand and though not as available, the overall cost seems to still be less. I am going to start looking for the AAA size since that is what fits my small flashlight, wireless mouse, and more. These are often left on by mistake or used extensively and are essential to function at all times. I see the listing for digital cameras, high powered toys and grooming devices on the package. That may include some oral care/inter dental devices which may need batteries. These are listed as Rayovac’s longest lasting battery made in the USA.

Rated 5 out of 5 by from Satisfied!! So I had been going through batteries like crazy, because I found this trash can that I really like. It has a sensor that opens the trash can lid so you can toss the trash in! But it does take 6 batteries. I know that is a lot! Well we went through several packs of batteries because they just wouldn't last that long, they would die within that first week. Then we got these, so I was like okay it's worth a shot! Well guess what, these batteries are still installed in my trash can right now, and it's still going strong!! They have been operating my trash can sensor for about a month now. I won't be wasting anymore money I will buy these as I know they are long lasting! This is also a brand that has been around for years and it's only gotten better! I'm satisfied and happy that it functions my trash can daily!

Rated 5 out of 5 by from Long Lasting power! I tried the Rayovac Fusion AA Batteries and am thoroughly impressed!! I use a wireless mouse at work, and I tend to go through batteries like crazy. I was so excited to potentially have a longer lasting battery. I exchanged the battery I currently had in my mouse with the Rayovac Fusion AA Battery and was impressed! After 3 weeks, I usually have the red blinking light of disappointment that tells me I am nearly out of juice; but, three weeks after using the Rayovac Fusion Battery, my light is still glowing that beautiful green! I will now, and forever, use these little gems!

Rated 5 out of 5 by from Long lasting batteries! We've been using the batteries with the controls of our Wii, we play everyday for like 45 minutes or more and the batteries are still working after 3 weeks approximately. We're definitely getting more of these by our own, they're very long lasting. I received this product for free in exchange of a honest review.

Rated 5 out of 5 by from Noticeable difference I finally got a chance to use these. The batteries in my mouse ran out. I put these in and I expected them to be like new but they actually seemed to be more powerful. My mouse responded faster and the batteries are lasting a lot longer before they run down. I use my mouse daily and for hours so I usually have to change batteries often. So far, these have worked longer than my usual brand.

Rated 5 out of 5 by from Awesome batteries! I received these batteries to test and so far they are great! I put 4 of them in my son's Leap Frog Explorer. I wanted to see how well they work in high-powered devices. So far so good. I'm hopeful that they will last a lot longer than other AA batteries as advertised. I'll be using them in our TV remote, my rechargeable toothbrush, etc. when needed. I have confidence that these batteries will last a long time.

Rated 5 out of 5 by from very long lasting batteries After receiving the Rayovac Fusion batteries I tried them out in my little water fountain with light. It seemed like my fountain worked better and hasn't lost power yet. I am very happy with them and plan on buying more in the Future. Fusion is the way to go.

Rated 5 out of 5 by from Long lasting Received these in exchange for my honest opinion! I have been using these in remotes and in our toothbrushes and one in a gaming remote. All have lasted longer than some other batteries I've tried. I usually change every three weeks or so and so far they're still going! I like these and will be purchasing more!

Rated 4 out of 5 by from Work Well I decided to try out my new Rayovac Fusion AA 8 Pack batteries out on my remote controllers and so far so good. I have not run into any problems and they are super easy to install.

Rated 5 out of 5 by from Fusion batteries--non stop working I received this 8 pack of batteries to try out. These batteries are awesome. We have split them up into my daughters toys, my hubby's electronics, and razors. They are holding up perfectly with no apparent decrease in power from them. Typically, especially with razors, they die fast. Not these. It's been about a month and they are going steady and strong. As for toys, they are holding up every bit as strong as well. There is one toy in particular that my daughter messes with ALL the time and typically needs batteries every month. Not these. We definitely will be purchasing these in the future.

Rated 5 out of 5 by from Fusion = long lasting strong battery I received these batteries to review and I'm happy to get to try them. I put them in my toothbrush,flashlight, and radio at work and I saw a significant power increase in my toothbrush stronger and flashlight brighter. I haven't had to replace the batteries in over a week not like the other batteries which only lasted a week in my radio. I highly recommend in buying these batteries they are worth every penny you spend.

Rated 5 out of 5 by from Fusion AA Great product. I received this as a product to try and am amazed at how well its doing. Using them in so many ways like flash lights, kids toys, etc. Lot s time the grand kids forget to turn the item off and its left going and they still hold up a lot longer than some of batteries on the market. Another plus is there made in the USA and are guaranteed with information on the back on pkg. should you need to do so.

Rated 5 out of 5 by from Awesome batteries They really do last a super long time so you don't have to change them as often which is a big plus in my book. It's nice to not have to change out the batteries so much. I received these batteries to try.
