Duracell Coppertop AAA batteries with Power Boost exceeded all expectations. The 8 pack provided reliable power for our household needs. They truly deliver long-lasting performance, crucial for our everyday use. These alkaline batteries proved to be reliable and well-suited for various household devices. Highly recommend to anyone valuing reliability and quality!

Excellent batteries at an affordable price They are reliable and I have used this brand for ages They are somewhat expensive but worth it I do dislike the fact that once the pack is opened the shelf life seems to go down rather fast

I use these both at home and at work. They last a long time especially in smoke detectors. I also like the 5 year guarantee.

The Duracell 9 volt batteries are the best! I've used them in walkie talkies that get used daily and the batteries are still going strong. I would highly recommend them.

This product did not disappoint. From the packaging to the performance, everything was exactly what I was looking for. The twin pack is twice as nice for the price and the product is as always, flawless and reliable.

I purchased a package of Duracell 9V batteries with the intent of using them in my smoke detectors. Little did I know that they would be used for something more important. Hurricane Ian was heading our way so we gathered our supplies and started replacing batteries, turns out it was my daughter's flashlight that needed 9V. We spent 2 days without power, and those batteries never failed us. Duracell is our go to batteries for everything now.

I recently purchased these Duracell 9 volt batteries to power my smoke detector. I love using Duracell batteries for that because they last a long time and Duracell's reputation helps me to feel that my family would be safer if we ever had a fire in our home. I always keep Duracell 9 volt batteries on hand for whenever the current batteries in my smoke detector run low. The fact that these batteries are guaranteed to last 5 years always makes me feel confident that they will last until I need them.

The packaging is so sturdy! These batteries seriously made a difference while using them for a long period of time! We didn't have any issues with defective batteries!

The product is working great and we agree that it should last a long time.

These are still working. I am happy with these batteries, so far. I was reimbursed by Field Agent for my honest review.
