Optimum AAA Batteries with 4x Power Boost Ingredients, 4 Count (Pack of 1), Triple A Battery with Long-lasting Power, Alkaline AaA Battery for Household and office devices

Really optimum AAA batteries here. I used them for my razor and remotes. Have not had to replace in remote in over a year now. Razor, depends how much I use it but it's better then the dollar store brand or other inferior brands. They last quite a long time, and I prefer to spend my money on something of quality rather than a pack of 12 and replace every month.

I've used Duracell batteries so many times that it's impossible to count. I find their brand to be the best available and this specific type is no exception. They come well packaged, they're easy to install, they're made well, and last a very long time under typical use. I'll always go back to the Duracell brand as I find them to be the most reliable when I need them. Zero complaints here. Trust the copper top!!

Made all my kinky stuff last all night !!

I don't necessarily need premium batteries in every little device around the house, but there are certain things where I don't want to constantly wonder whether the batteries are getting weak. That's where I tend to use Duracell Optimum. These AAA batteries have been dependable in the electronics I've used them in, and I like keeping an 8-pack available for remotes, small electronics, flashlights, and other devices that take AAA batteries. Duracell advertises these with its “4X Power Boost Ingredients,” but I'm not running controlled battery tests at home to determine exactly how much additional performance I'm getting. What matters to me is that they provide reliable power and I don't find myself replacing them constantly. They do cost more than basic or generic AAA batteries, so I probably wouldn't waste them in something that barely uses any power. For devices that get regular use, though, I'm willing to spend a little extra. Are they exciting? No—they're AAA batteries. But when I reach for a battery, install it, and don't have to think about it again for a while, that's exactly the experience I'm paying for.

I bought these last week because my kid's RC controller went through cheap alkalines too fast. The voltage stays strong as they drain so the toy actually performs right. My only complaint is the plastic tray is way too hard to pry open. Worth knowing: The storage tray requires a lot of force to slide open.

Worked fine.

After reading other reviews, I bought these for my garage door opener keypad. Other reviewers said they were the best choice. I chose them especially for a quality battery that will hold a charge when it’s cold.

has lasted a good while
