Energizer Recharge Universal Rechargeable AA Batteries (2 Pack), Double A Rechargeable Batteries

Batteries work great, they come precharged and ready to go. They recharge in a couple hours using my very old Sony Cybershot nickel metal hydride recharger. Glad I got them.

I've used Energizer rechargable for over 10+ years. The batteries have evolved a little, increasing the mAhr output over the years. For me energizer is a trustworthy brand. My "charger" is also quite old. I think it works great. In fact, I do not see a similar rapid charger for sale these days. Perhaps I'm fortunate.Pros:- name brand- quality- great for home electronics, remotes, Wii, game controllers, etc- quick recharge if you have the correct chargerCons:- slow recharge with the slower charger- a little on the pricey side to start with. But over time you break evenSuggestion: do not mix and match newer rechargeable with the old. I personally feel it leads to more recharge cycles on the newer. so I always mark my batteries and try to use old with old and new with new. When the charger flashes red for a battery, then its life it done and I recycle it

Short and to the Point Review:Love these batteries. Never let me down. Best rechargeables I’ve used.Long and Rambling Review:From the 1970’s to about the early 2000's, most rechargeables were crap. And expensive. Didn’t matter if they were for small electronics or professional power tools, didn’t hold a charge for long and expired way before they should have. I used to recharge regular batteries (a big no-no) when I was a kid in the 60’s with a unit from Radio Shack and had as good luck as these older rechargeables. I gave up on any rechargeables for a few years and then decided to try again as I got tired of purchasing regular batteries all the time as more and more electronics demanded batteries.Bought my first Energizer Rechargeables in 2014. They are still working. Yes, I know the battery chemistry has changed over the years and it was about time. I Sharpie all my batteries with the date I put them into service and most of the 2014 units recharge and function. Only 2 died recently of the first batch I purchased. They really do last 10 years.I have purchased several new devices in the last few years that require AA’s including two Zoom field recorders. I initially purchased Panasonic eneloop Pro batteries because of their high capacity. They work flawlessly but are on the expensive side.Because of the longevity of the Energizers, I purchased a new set. Their capacity is almost the same as Panasonic’s, but I know the Bunny will last a long time. The AAA’s have lasted as long as the AA’s. I also have had good luck with the Rayovac Rechargables and still have working units from 2014.One note to consider. All these batteries are 1.2v, which work fine in most devices. The Zoom recorders allow you to define which type of batteries you are using to help determine when they need to be recharged or replaced. Some older electronic devices will not function correctly and need 1.5v batteries. If you have a problem with your older device, it’s probably not these batteries.Retired Military Aerospace and Industrial Manufacturing Engineer

I decided to test rechargeable batteries for photography, with my Nikon D750. The battery charger charged the batteries quickly and powers the camera well enough for my test. I will try to give an update on the performance in a few days. I recommend using a wall adapter to properly charge the batteries. A USB port in a wall outlet is not enough and will take hours to charge.Update 4-26-202225:I had a wonderful photo session today. These batteries worked great. Absolutely no issues with pics/videos, even on high power/quality settings, I used a high-quality Nikon 85mm lens. While these batteries worked great, I did not realize how power hungry my camera was. These batteries lasted maybe just over 2 hours, but they did work and worked well. Fortunately, I had an OEM battery, so I was able to continue my photos. Bring extras if you chose this type of battery, or an OEM.

I received the four batteries and put them in the charger. I was concerned the charger (or batteries) might be faulty because after 12 hours (the max time indicated on the manual), the batteries had not yet fully charged. The charge indicator light on the charger remained red until about 16 hours of charging. However, the batteries seem to have been charged and work as advertised.

Work as advertised

This charger is a great value—especially if you catch it on sale. The included Energizer batteries are a nice bonus, but what really impressed me is that it works perfectly with other brands too, like Amazon Basics rechargeable batteries.Why I recommend it:Reliable Charging: I’ve used it with multiple sets of batteries and haven’t had a single issue.Cross-Compatible: Don’t feel locked into Energizer batteries—this charger handles others just fine.Simple & Effective: Easy to use, compact, and gets the job done without any fuss.Great for Stocking Up: I’ve purchased a few of these now for different spots around the house.If you’re on the fence because you think you have to use Energizer batteries—don’t be. This charger is flexible, dependable, and a smart buy.
