I've always opted for Duracell batteries where I can as I've trusted the brand more than any other battery, and these did not disappoint. I used them as a replacement in my wireless keyboard which had been on the fritz (the keys only functioning half the time due to dying batteries). I replaced the old batteries with two of these and the keyboard is working better than ever, honestly feels like it has more connection than I've ever had (ie no pauses in typing). I love the 12 year storage guarantee, but do need to say that the packaging feels a bit dated, and I'm not sure what power boost ingredients are as there is no explanation on the packaging.

I would also like to know if these are made in the USA on the package rather than having to see the imprint on the battery - I much prefer to support locally made products. All that said, as above, it's a very good product as expected from a trusted brand, just might tweak some of the packaging.

I think these are great, I normally buy the regular Duracell batteries, and they are good as an overall battery, I find I'm needing to replace them in my insulin pump regularly. The manufacturer recommends Energizer batteries but I wasn't really happy with the performance so I switched to Duracell a year after using the Energizer Batteries that Medtronic Recommended. I put the Duracell Power Boost battery in the Insulin Pump, and it's been 2 weeks and still going strong. I'm floored to say the least. Yes these are a little more pricey than the regular ones, however with the length of time I got off of one battery it was paid for itself, and I still have 3 batteries left. I was a bit skeptical at first, but I'm sold!

The thing I appreciate most about these Duracell batteries is their lastability - twelve years in storage! Their lasting powers certainly vary with what they're used in, but I know from experience these will keep powering on for as long as you need them to and then some. It's a little thing, but I also like the way they look and feel. They're a bit heavier than other AA batteries, I think, and they feel extremely sturdy. Overall, these are high quality batteries from the way they look to their usage. While they're more expensive than some other brands, I think Duracell batteries will last longer, making up for the price difference.

Duracell has always been a long lasting battery that I have favored over the years and this Power boost one did not disappoint. You can immediately feel the difference in power when you first install the battery into your appliance. I like the design it comes with. The vertical and horizontal lines is pleasing to look at for some reason. Maybe because it's different. The battery is expected to last for quite some time as this has been the case with my previous Duracell purchases. Overall a great battery from a great brand.

I used these batteries to replace dollar store off brand batteries in my flashlight. It is back to being very bright and steady where before it was weak and dim. These batteries work well and so far with extended use have not worn out yet. I like the way these batteries look and the matt ridged texture helps with grip and install. The package says, "NEW POWER BOOST INGREDIENTS," which I'm not sure what that means. The back references guaranteed 12 years in storage, so I'm not sure if that is what Power Boost does or what. It is nice to have the dates etched on the battery about when those 12 years are over.

I bought these Duracell batteries as a replacement for the factory installed batteries in my remote that drained extremely quickly. I was looking for batteries with more durability that were manufactured by a well-known brand. The packaging felt high quality and the batteries were easy to install. The price was a little high but it justifies the quality. I have been using them for a couple of weeks and they power my remote very well with absolutely no interruptions. I am very pleased with these batteries. They really gave my remote a power boost.

Packaging of the product is great with an easy to open back so you can the amount of batteries you need for the occasion. I used two for a remote and it worked just fine. I took the other two to a flashlight and it gave it a nice brightness to it that I like to see with these type of products. Fully charged and with the guarantee that it could last twelve years puts my mind at ease. Great value for a long while. I don't know how much that guarantee will hold up but I guess I will find out in twelve years after storing them. I think the in storage part should be bigger seeing how that can be overlooked and misunderstood. Overall I will continue to use this product and share it's reliability with others. Good battery for a good price!

After purchasing these Duracell Power Boost batteries, I decided to put them to the test. I have a LED flashlight that I had just replaced with new batteries. I removed those and replaced with the Duracell Power Boost batteries. Both myself and my husband agree there was a noticable difference in how bright the LED flashlight was when the Duracell Power Boost batteries were used. And even though I just installed the Power Boost batteries, I have full confidence they will last longer than the brand of batteries I was previously using in this flashlight. I will definitely be replacing the batteries in other electronics I use with the Duracell Power Boost batteries.

Duracell is definitely our go to battery in our household. When it comes to smoke detectors, flashlights or anything else we keep on hand for emergencies, Duracell is the battery we know we can count on. I like that even if these batteries stay in an unused product, I can count on them to work when I need them. I live in Florida where we lose power quite often during hurricane season. I know that Duracell batteries will get me through just about any outage. They last for many hours, and don't go bad while in storage. Great product to have on hand!

Worst Batteries on the Market

Worst product ever. I used to like Duracell batteries and used them almost on all my devices. However, over the last few months, my opinion of Duracell batteries has changed 180 degrees. A couple of months ago, my emergency portable radio went dead so I decided to change the batteries. When I opened the battery compartment, both batteries had leaked ruining my emergency radio completely. Today (Sep 13 2019), one of my 3 (I have a 3 zone A/C) A/C thermostats was blinking meaning the battery was low. When I opened the battery compartment, to my surprise, both Duracell batteries had leaked so bad that they had ruined the thermostat contacts. The battery case itself had expanded so bad, it had ruptured and I needed a screwdriver to remove the batteries. Now having had 2 ... MoreWorst product ever.

When I opened the battery compartment, to my surprise, both Duracell batteries had leaked so bad that they had ruined the thermostat contacts. The battery case itself had expanded so bad, it had ruptured and I needed a screwdriver to remove the batteries. Now having had 2 recent Duracell failures, I checked my other 2 thermostats and guess what? The Duracell batteries had begun to leak as well. So over the last couple of months, I've had 4 devices ruined by Duracell batteries. I now used Energizer batteries throughout all my devices in my home, in hopes that these will prove better, have better quality, better design, and not leak as they advertize that Energizer batteris will NOT leak for at least 2 full years after the battery life has been depleted, but we will see. But back to the issue: DURACELL BATTERIES ARE THE WORST of the disposable battery market worldwide. DO NOT USE unless you want your devices ruined by leaking batteries.
