I like the value of the bulk buy. These came as PowerBoost which I think is their default standard battery. We go through a lot of batteries, so we like the Copper Top. Most of the time I don't have a leak problem and they seem to last a long time.

I just received these they were packaged nicely. I got 28 batteries for $9 which is a great deal. I am using 18 of them to put into my under the cabinet puck lights. Hopefully they will last as long as it states. I will update my review after a little while of using them to see if they actually last.

I have 7 wifi connected smart door locks that are power hungry and eat batteries for lunch. Each lock takes 4 AA batteries at a time. I tried a number of different battery brands. Some lasted as few as two weeks. Duracell Coppertops lasted the longest by far, around 5 - 6 weeks. There are variations on the Coppertop battery. The version with the faint rings around the coppertop part of the battery (Optimum or Power Boost) are more expensive than the original coppertop and do not last as long. The coppertop with the red lower part of the battery (Quantum) also doesn't last nearly as long as the original coppertop. Another brand, ProCell, also doesn't last as long as the original Coppertop.

I always need to have these on hand. Especially the AA. I have stick candles in my windows all year long and also many other things that take AA. I've tried all the others and for the money you cant beat this deal. I hope it stays this price for a long time they will have my repeated business. I've tried the dollar tree and they are a decent brand but they dont last like these. I like Energizer batteries but they are too expensive. These are great for my purposes.

I run a live sound and wedding dj business and I got tired of dealing with rechargeables that never would hold a solid charge. I switched to these and I am running multiple weddings on my microphones now and they still show full battery. No question that these are worth the money if you need consistency, longevity, and reliability.

They were a great deal! We are going through them quite rapidly like 4 a day with our portal fans no matter which brand. Just for the walk from school and the dollar tree batteries (cheaper and last longer in the portal fans). If you can recommend 20+ portable fans that are reasonably prices maybe the new neck ones? We need 11 adults and 9 kids for the time. We honestly need more for all the walkers and parents, crossing guards, School staff because this year’s heat in Florida is over the 100’s! The school board is making us wait even longer for dismissal from the beginning it was walkers 1st not we all have to wait for the buses which have AC bf our children may be dismissed to us. Heatstroke is real. The school is not in an area that they can be afforded then littler children are dismissed before anyone waiting for siblings and grandparents as well as people like myself who are handicapped. Please if any suggestions or assistance/donations can be provided that would be such an appreciated amazing blessings!!! Thank you kindly for any assistance!

Buy in bulk and get it delivered the next day.

I really like and trust the copper top batteries... Duracell... a lot! They come in a nice-sized, affordable pack and they always have a long life! If you need a pack of batteries, give these a try!

Had these leak battery acid in my flashlight

This a brand name battery so of course they want to keep their name good so they produce a good product a good value for the money. I have ACDelco and several other batteries and they all perform the same or at least close. I'm still in the trial stage but I'm expecting Duracell to outperform in the end for the extra cost that I'm paying. We'll see. waiting to see . but happy
