They work really well. They last a good while. Very affordable. These met my expectations. Definitely worth it. No need to improve the product. I use these for everything that needs batteries. I definitely recommend these to others.

Expensive battery's that do the exact same job as a value version. You pay for the brand name, not the product. Personally, I opt for the cheaper options.

Love these for my blink camera. I wish they lasted a little longer but they still have a long life on them. I love that they can be used in any device that takes AA battery. They are a bit expensive for how many you get in a pack.

Our family likes energizer batteries, they seem to last longer than others and are at a better price point. We use them in almost everything we own and in multiple baby toys. 

decent batteries! the life isn't nearly as long as they tout, my clock will start to run behind within a few weeks of replacing batteries and my other tech things will start to run lower as well.

My daughter leaves her toys on and plays with them a lot. I go through a ton of batteries. These have cut down on how many I have to buy because they last longer then most others I've tried. Real money saver in the long term.

At first I thought these energizer ultimate lithium batteries were rechargeable (wrong!). They look nice, and their performance is great, actually. However, they Do NOT last as long as comparable batteries.

These are the only brand of batteries we use in our household. All of my sons toys have energizer batteries in them. They work for a long amount of time, as long as we keep the toys off when not in use.

Just like Duracell, this is a high quality, long lasting battery and highly recommended if you want your battery powered items to work for a long time. Rarely needs changing!

Seems like batteries don't last as long as they use to with how much they cost these days. I can't tell much difference in the longevity between these and Duracell batteries
