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

4.67 stars. Seems to work fine for various brands of NiMh AAA & AA batteries. It's a dependable, simple, brand name charger. BEST FEATURES: ++ Plugs directly into an outlet or power strip. NO fussing with USB chargers or cables, or ports than can go bad. ++ Comes with 4 Energizer rechargeable AA batteries, so it's a good deal, price-wise. ++ Simple, large, bright indicator: red (charging), green (DONE!), or flashing red (problem with a battery). ++ Charges our Tenergy or Energizer brand NiMh batteries well, & also generic ones from outdoor solar lights. ++ Has an opening in the back, so it's easy to push out the batteries when they are fully charged. DOWNSIDES (small, but good to know): -- You cannot charge just ONE battery at a time. You must charge either 4 or 2. If charging 2, they MUST be in either the 2 left-most or 2 right-most slots. This was not obvious when we purchased, but we did find the "CHARGE 2 OR 4" statement afterward in the additional images. -- Included printed directions are welcome, but are fairly small print. The image of proper battery placement could have been larger and better designed. IMPORTANT: It's NOT for NiCd or other non-NiMh type batteries. If you need to charge more than one flavor of battery, look elsewhere. This one is for NiMh batteries only, in AA or AAA size only. WOULD WE BUY AGAIN? Yes.

Works a stated and is perfect for controllers and they last longer than regular batteries

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.

The product received was as described and works perfect. I bought this along with rechargeable from amazon for her VR controllers. Batteries last about 3 days plus before needing recharged. Happy daughter and happy parent!

Better then the off brand rechargeable only problem is batterys don't last to long for gaming but great for other uses for the price I'd definitely recommend

I purchased in 2021, I have used these in my bathroom for 4 1/2 years and they are just now starting to need replaced. They do take a few hours to recharge but usually last me more than a month. I liked the AA size so much that I got AAAs as well for my remotes.

What you expect, 4 batteries with the chargers, pretty good and works perfectly.

I love that it comes with some AA batteries, and fits AAA batteries too. The charging light is very bright and easy to see. After charging it fits away nicely in a drawer thanks to the plug being foldable. I found that it may misdiagnose some batteries as 'bad', it happened to me once, and the batteries I was trying to charge were brand new. If that does happen the best course of action is to take the batteries out, unplug the charger, put the batteries in the charger and plug the charger in again, the ol' turning it off and on again schtick. I found that fixes the issue easily enough, but if it persists than I suspect a battery may actually be dead.
