These are the best batteries that I have found for my smoke detectors.

I've always been using these batteries for years now. I used them for my fire alarms, it always last for a year or two at least. That's why I liked them so much

[This review was collected as part of a promotion.] I received the C 4-Pack Fusion batteries to test and let me tell you............I have 5 Grandsons who wear me down with batteries. They also like swiping Grandpa's flashlights which his one takes these size batteries. One of the boys had left the one light on all night and I couldn't believe that when I checked in on him in the middle of the night the flashlight was still on and working.............now let me tell you any other batteries that I have used they would of not have lasted this long ...........they would of burned out in just a few hours and I want to say that these batteries were still working after at least 6 hours of continued use..............I would recommend this brand of battery to anyone who have children that have a great deal of battery operated toys............they really do outlast all others.

[This review was collected as part of a promotion.] These C 4-Pack FUSION™ Premium Alkaline Batteries are great to have around for baby gear such as a swing or bouncer and certain other kids toys. The battery life is good ans I would recommend them to family and friends.

I purchased this brand based on the reviews it gave. I am using them in a TENS unit and they work great

always wonder how the company came up w the name for these batteries. lol! but theyre a good brand with a reliable product

[This review was collected as part of a promotion.] Perfect batteries - these work great and I haven't even had to change them out for 6 months on controls that I use everyday! I can't believe they are working this well. Very impressed.

I will let you know as events warrant, you can't rate a battery by it's tentativeaty, but more by it's tenacity. if this confuses you, blame the people who don't teach.

bought for a alarm clock. placed in clock battery died in 30 days. but states have 5 year guarantee.
