Rechargeable

Reliable and long-lasting — these Duracell Coppertop AA batteries have become my go-to for all the small devices around the house. They hold up well in remotes, clocks, and flashlights, and I like that they’re backed by a brand that’s been trusted for years.

Buena duración, solo que son un poco más grandes de las normales y en un mouse inalámbrico quedó muy justo casi no la logro quitar.

Very Disappointed. They ranked so highly on project farm's online tests. Bought these because they were less expensive than the brand I've been using. They last less than 50 photos in a simple point and shoot camera (with the flash off most of the time). Disposable batteries, older versions of this battery and Nuon brand last for 150-200+ photos. Also, these seem to self discharge significantly in just 24 hours. Gave them two stars solely because they do recharge...kind of. Tried three different chargers thinking maybe that was the culprit. The output tests lower on these than the Nuon brand, Harbor Freight's brand and older Duracell's. Probably deserves a single star.

Duracell has always been my favorite brand of alkaline batteries, & now have become my favorite Nimh rechargeable batteries. I use 3 different brands...& so far I prefer Duracell (sold & delivered by Amazon) over Energizer. To be fair, I haven't used my Eneloop rechargeable batteries yet...so I can't say anything about them...yet. I plan to in the future though. They have a great reputation. Anyway, the Duracell that are copper & green...have been extremely consistent when I charge them on my charger that is not a basic battery charger at all. It tells everything you need to know about a rechargeable battery when charging...& when they are finished charging. It charges 4 batteries at a time. The voltage, maH (capacity), & ma (resistance) are basically identical in every way after charging. That says A LOT to me. They also have a higher maH @ 2,500....compared to Energizer. And so far, none have gone bad on me yet. A couple of my Energizer batteries have lost their usefulness. I can see that there resistance has become way too high to use, so they were retired. To be fair, I've had them for quite awhile now. Anyway, I really like & trust Duracell, a lot. So far.....they've been great. I only use rechargeable nimh batteries now. I really like the idea, of being able to recharge batteries...& use them over and over again. Saves money & not wasteful! I'm not sure if there is any difference, between the ones that are copper & green vs. the ones that are copper & black. Most likely, they just changed the way they look. I like the way the copper & green ones look...lol. I know it doesn't make any difference on how they perform, of course...but they look "cooler" to me. To sum it up, I would definitely recommend Duracell. They are very consistent...& last a long time in my devices. I mainly use AA batteries, so I can't form an opinion on their AAA batteries, yet. I hope this has been helpful.

Long lasting. Use it for mics at my church

Really good batteries and bathed maintain a charge for quit a long time. Impressed.

Slightly larger than standard AA batteries and won't fit in everything, but work well with what they do fit in.

These are a wonderful choice to avoid the waste of conventional cells HOWEVER they only work reliably in limited applications: 3-4 cell flashlights=super!, TV remote control=useless! Haven't tried in wireless telephones because they use specialized batteries. Our big LED wall clocks advise not to use them, but they work fine anyway. These cells are well worth the investment for use in appliances that have compatible current demands. Test first and have a few conventional cells on hand in the event that rechargeables simply aren't up to the task.
