Duracell Optimum Coppertop AA Batteries with 4X Power Boost Ingredients 30 Count

Reliable, dependable and always what I buy.

These batteries have a much longer life than the Duracell Power Boost. We use them in our Keypad Entry Locks and they last longer with the same amount of use. Our Locksmith recommended these batteries and he is right!

Holds the charge ok

Great improvement in product and so far have out lasted the basic dura cell battery.

Battery package was open with batteries scattered throughout the bag. I’m questioning whether these batteries are new or if someone used the batteries and returned them and now I’m getting someone else’s used batteries.

They last. I have so many battery operated devices and candles... I go through a lot of batteries. Cheaper alternatives really don't offer savings, when they barely last a more than a week or two. These are great batteries and will give you good mileage for your buck.

Long lasting

I’m a videographer and my audio recorder (The tascam dr70) is an energy hog. I didn’t measure but I can say the optimum gives around twice the recording time than the basic Duracell batteries.I think these are a gear buy.I do have to point that the second batch I got had a few out of date batteries with some moldiness around the positive polar but Amazon took care of it and sent me a new package promptly.TL;DR - Great batteries for a decent price
