[This review was collected as part of a promotion.] Energizer is a well known brand that makes good quality products. This one is no exception. These batteries outlasted other brands I have tried, no contest. I have used Energizer my whole life, very familiar with the bunny that keeps going, and going, and going...

This particular type is great for my kids’ toys, flashlights and some of my smoke detectors. They are long lasting, and I have never had my energizer batteries leak. Overall, these are a great product from a great brand.

Compared to other brands I like that I don't have to buy batteries as often because of the long lasting power they give my electronics! I love the quality of these batteries and highly recommend them!

[This review was collected as part of a promotion.] I use these batteries for my tens unit. I used to use generic batteries, but they would only last one day. I need dependable batteries when I’m in pain! I’ll only buy Energizer batteries to use in my devices! Would you trust a generic battery in your smoke detector??

[This review was collected as part of a promotion.] I haven't had these long enough to know how long they will last, but I received this product quickly and they work as advertised. The packaging is nice too, because you can store the batteries in the package after use. I received 4 C batteries in this package.

[This review was collected as part of a promotion.] I love these batteries. This has always been and will always be a very dependable, reliable, and trustworthy brand. They are working well so far and I expect them to last long. I will definitely recommend this to everyone.

[This review was collected as part of a promotion.] I've had these batteries in a frequently used flashlight for over a week now, and there's still plenty of power left with no perceptible dimming. Usually, in the same time period, the batteries I usually use, are already dimming. Out of the box, the batteries were all at established advertised parameters. So, absolutely no complaints there. Energizer is occasionally overlooked compared to other options, but I find them to still be a really solid value battery, especially this type of battery. Really, I can't think of anything wrong with these. Obviously, rechargeable is the way to go in most cases, but these are great single drain batteries. Recommended 5 stars Cheers!

[This review was collected as part of a promotion.] We have used this is a toy that is getting A LOT of use. Two weeks of a ridiculous amount of use and they are still going strong. I have a battery tester and they are still in the very good range so I guess we have a lot of use left. No corrosion has been seen after all the use, either.

[This review was collected as part of a promotion.] I highly recommend these batteries last a really long time! They are rechargeable too. Alot if my kids toys use c4 so these came really handy since these specific ones are a bit harder to find in stores.
