Energizer Recharge Universal Rechargeable AA Batteries (16 Pack), Double A Rechargeable Batteries

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.

good quality brand name good price

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.

First off, ENERGIZERS ARE AUTHENTIC and legit but DO NOT PLAN ON USING THEM DIRECTLY OUT OF THE PACKAGE! Despite this listing's claim that these batteries have been packaged & shipped fully charged and ready to use, you will almost assuredly find that your new Energizers are incapable of more than faintly lighting a small LED light and won't have sufficient charge to run any motorized or power hungry devices at all when you first unbox them. Indeed, you'll be putting them on the charger ....so I hope you have a newer or fairly advanced rapid charger to make quick work of charging these fully before first use. Thankfully, my Energizer branded 4 cell rapid charger took the entire pack of 16 from virtually bone dead to fully charged and powering 8 extremely realistic authentically hand-dipped wax LED flickering flameless Christmas candles for each of our home's front windows--in under 2hrs time. That includes the time spent carefully unpacking each individually wrapped taper candle and a set of brand new brass candle holders, charging batteries in 4 batches of 4 and loading each candle with 2 AA Energizers before setting them to desired flickering effect & brightness and placing them in all street facing windowsills while finishing up hanging of 3 remaining sets of lights around each window frame. Couldn't be happier. Sidenote: I used to be a huge fan of Duracell Quantum batteries and didn't realize just how much money & time lost to charging excesses I had squandered until I found myself in a bind while traveling & 3 out of 4 Duracell AA batteries suddenly failed recharging; leaving me to hurriedly find & purchase replacements from a limited supply of off-brands and various Energizers--so I selected Energizers & crossed my fingers. *Strike 1: Duracell* The set of 4 Energizer AA rechargeables I chose was interesting because they included a FREE plug-in wall charger AND cost slightly less than the basic Energizer 4-pack without a charger. That purchase turned out to be an awesome deal in more ways than just saving me a couple bucks. The included Energizer charger turned out to be far more capable than my relatively new (<3mos old) Duracell 2x charger, which employed a tiny green LED (steady blinking or solid lit) in lieu of any meaningful charge progess indicators plus it annoyingly required batteries to be charged in matched pairs AND it never did indicate my 2mo old Duracell rechargeables were bad or failing. The free Energizer charger offered rapid charging, built-in battery testing & accurate time-lapse indicators for between 1 and 4 AA or AAA batteries AND allowed immediate confirmation & identification of 3 BAD Duracell rechargeables in a new set of 4! Score one for Energizer. Now, if that weren't enough, the Energizer rechargeables were incredibly reliable....longer lasting and quicker to recharge than the Duracell batteries I had long trusted. Another score for Energizer. **Strike 2 for Duracell.** Jump ahead 2 years or so and 5 out of 7 First Alert smoke detectors that shipped with long-life Duracell 9-volt batteries began chirping weeks apart after a mere 1 year in service. Having previously discovered & subsequently replaced a dead primary smoke detector downstairs, I was shocked and curious following installation of our new smart combo detector. I chose a brand new hardwired Google Nest Protect that includes battery backup ....and noticed it shipped with a brand new ENERGIZER ULTIMATE LITHIUM 9V BATTERY and upon reading that Nest engineers specifically designed & optimized the Nest Protect's dual mode smoke & CO smart detector to such exacting standards that they would only GUARANTEE the detector to never fail to operate correctly even during power outages for 10 years, as long as any required replacement of the 9V backup battery was done with the SAME EXACT ENERGIZER ULTIMATE LITHIUM BATTERY (or Energizer's latest equivalent upgraded lithium ion 9v in current production), it got me thinking. Less than a 1.5 years after replacing all 8 original smoke detectors in our home-- 1 smart Nest Protect using Energuzer Lithium backup battery and 7 conventional smoke detectors that came equipped with Duracell lithium 9V batteries-- 5 outta 7 of the conventional detectors began chirping within a week or so of one another while the Nest Protect worked flawlessly, completing its own weekly self-checks and never falsely alarming nor chirping at 2a.m. to warn of a low backup battery despite being 6mos older than these other 7 detectors that were now chirping for battery replacements 24/7. So I made the executive decision to replace all 7 Duracell backup batteries at the same time using the more expensive ENERGIZER ULTIMATE LITHIUM 9V instead of the First Alert recommended Duracells. It wasn't cheap ....but 3 years later and every smoke detector in our home routinely tests good and not one has chirped even a single solitary chirp! ***3rd and FINAL STRIKE for Duracell*** I owe it to the permanent switch to Energizer ULTIMATE LITHIUM batteries, which I now use exclusively in all of my battery powdered devices including remote controls and every one of our alarm / smart home sensors (some use coin cell batteries & I even order Energizer Lithium replacements for those). The only devices I use Energizer's RECHARGEABLE Ni-Cad batteries in are non-priority items and high consumption items like older flashlights and motorized RC kit cars, toys & Christmas decorations, etc. For devices that chew through batteries that don't warrant the expenditure for the lithium ion chemistry--which has a much more consistent drain & characteristically linear power output quite nearly to point of complete drain, as well as higher supply tolerances for peak bursts / transient current demands (common in dSLR flash modules) than traditional metal hydride & rechargeable nickel-cadmium chemistry or worse still, old-school alkaline batteries that give up most of their power early, rapidly fading to lower & lower output until dying with a whimper--you want the reusablility and cost-effectiveness of these Energizer Rechargeables!! Hope my experiences help you feel confident choosing the correct battery & brand required for your specific needs. Cheers!

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.

good

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

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.
