love these things, charge fast and last forever! use them for gaming and they last days sometimes. great quality ourchase def get these batteries trust me

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.

Rechargeable Batteries are much cheaper and last longer than other 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.

What I like The pack has lasted. I bought it in 2020, and I think most of the batteries are still in my collection. They tolerate regular rotation. Controllers, stair lights, and other household devices cycle through them every month or two. They use standard NiMH charging. A capable charger can charge, test, and occasionally refresh individual cells. The 16-pack is useful for a battery-heavy house. It supplies several devices and leaves enough cells to maintain a rotation. They keep working as they age. Performance is no longer uniformly new, but the batteries remain useful six years later. They are a credible Eneloop alternative. If the Energizer pack is priced well, I would not hesitate to use it. What annoys me My caveat is mostly comparative. I usually buy Panasonic Eneloop AAs. In my experience they have been the better value, and they remain my first choice. The Energizers have been good enough that this is not a complaint about failure; it is the reason the grade is B rather than A. Price needs to be checked at the moment of purchase. Pack sizes, sales, and marketplace sellers change the per-cell calculation constantly. My view that the Energizers cost more reflects the comparison I have made, not a permanent law of Amazon pricing. Divide the current pack price by the number of cells before deciding. The batteries are also aging. A six-year-old NiMH cell can lose capacity, develop higher internal resistance, or become less consistent with its neighbors. A charger-analyzer is useful here, but a refresh cycle cannot reverse every form of chemical aging. If a cell repeatedly tests weak or behaves poorly after a controlled cycle, recycling it is more sensible than endlessly deep-cycling it. Finally, do not mix cells carelessly in multi-battery devices. Use cells of similar type, age, capacity, and charge state together. One weak or partly discharged cell in a controller or light can be pushed into over-discharge before its stronger partners are empty. Who they are for, and who should skip them The Energizer 16-pack makes sense for a house with game controllers, stair lights, toys, remotes, and other devices that consume AAs regularly. It is especially useful if you already own a proper NiMH charger and want enough batteries to keep charged spares ready while other cells are in use. Buy whichever reputable low-self-discharge NiMH option offers the better per-cell value when you need it. If Energizer is cheaper or easier to find, this pack is a good choice. If standard Eneloops are cheaper, I would buy the Eneloops because they remain my preferred battery. Skip rechargeable AAs entirely if you use so few batteries that maintaining a charger and rotation adds more hassle than it saves. Also check device instructions when equipment explicitly rejects 1.2V NiMH cells or uses an airtight battery compartment. Verdict My Energizer Recharge Universal AAs have lasted six years of regular use in controllers, stair lights, and other household devices. They are aging, but they continue to charge and work. Grade: B. They are good rechargeable batteries and a legitimate Enveloop alternative. I would buy them again at the right price, but Enveloop remains my first choice.

good quality brand name good price

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 charger Cons: - slow recharge with the slower charger - a little on the pricey side to start with. But over time you break even Suggestion: 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

NOTE ON BATTERY TESTERS: Battery testers designed for standard AA batteries are calibrated for alkaline batteries, which start out at 1.5v and gradually decline. But, these batteries are NiMH and output a more or less constant 1.2v until they are dead. Because the voltage of a fully charged NiMH battery is substantially lower than a fully charged standard alkaline AA battery, a standard AA battery tester will likely indicate the battery is weak or dead.

These rechargeable batteries are nothing short of outstanding! I was impressed by their performance when they first came out when I was a kid and I still am as an adult! They hold a charge incredibly well, lasting significantly longer than many other rechargeable batteries I've used. The charging time is efficient, and they’re ready to go again quickly, making them perfect for high-use devices. What truly sets these batteries apart is their consistent reliability. Whether powering up remotes, flashlights, or toys, they deliver steady, long-lasting power. The fact that they are rechargeable also means I’m reducing waste and saving money in the long run—it's a win-win for both my wallet and the environment. Additionally, the batteries come with a sleek, user-friendly charger that fits conveniently on my desk. That thought went into the design and functionality, making the entire experience seamless and hassle-free. Overall, these rechargeable batteries exceed expectations in every way. They combine top-notch performance with eco-conscious benefits, making them a fantastic investment. Highly recommended for anyone looking to make a smart, sustainable choice!

Brand new, high performance rechargeables.

Works good it recharges not much to say.

Es wurde minderwertige Leistung geschickt. Händler hat den Preis nachgelassen. Folge- Akkus halten nicht lange.

I had purchased a pack of 8 more then year ago, I'm really impressed with performance of these batteries. This battery hold the charge for a year. My earlier experience with Duracell rechargeable was not good and they didn't response on warranty claim.
