[This review was collected as part of a promotion.] Energizer is a brand that I can trust. I like to keep different sized batteries on hand for many different needs. 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.

[This review was collected as part of a promotion.] Only batteries I use. It last a very long time, I don’t have to be changing regularly like I used to with other brands, I have had too many flashlights, radios, other battery driven devices ruined by Duracell and other low quality batteries. Never with Energizer batteries, will never buy any other brand that’s for sure.

[This review was collected as part of a promotion.] I highly recommend these C batteries by Energizer! My electronics run great on them and they last so long! 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 have 3 little ones so I don’t have to explain how many batteries we go through, but we have used these in a toy that has been on non stop for about a week and they are still going strong! I would definitely recommend these for toys or anything that is used often.

[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.] I wanted this multi-pack of Energizer 9 V Max batteries to power my smoke alarms and as backup power for my alarm clock. These Energizer batteries perform exactly as expected, and I'm very pleased with them.

[This review was collected as part of a promotion.] These Energizer C4 Max batteries work well. I use them in my flashlights and in a small lamp that I bought. The lights are bright and the batteries seem like they may last long time. I have enough spares to last awhile.
