Amazon Basics 8-Pack Rechargeable AA NiMH High-Capacity Batteries, 2400 mAh, 1.2V, Recharge up to 400x Times, Pre-Charged

These batteries are great value and recharge no problems, last a good time before requiring recharging, I suppose depending on use

I’ve been genuinely impressed with Amazon Basics AA and AAA batteries. They deliver consistently strong, reliable power across everything I’ve used them in — from TV remotes and wireless keyboards to game controllers, smart home sensors, and kids’ toys. Performance has been comparable to far more expensive branded batteries, with no noticeable drop-off in power or premature failures. What really stands out is their reliability over time. They hold charge well in low-drain devices, don’t leak, and feel dependable even when left installed for months. For everyday household use, they simply work exactly as you’d expect a good battery to work — no fuss, no surprises. The value proposition is exceptional. You get dependable performance at a price that makes sense, especially if you go through batteries regularly. They’re ideal for bulk buying without feeling like you’re compromising on quality. Overall, these are batteries you can buy with confidence. Practical, reliable, and excellent value — Amazon Basics AA and AAA batteries have become my default choice and I see no reason to switch back to more expensive alternatives.

Good value although some batteries don’t last as long as they should.

I bought these rechargeable batteries for one reason: **Christmas lights.** Hours and hours of Christmas lights. Days, even. Weeks, if necessary. I wanted illumination so steady and so relentless that even Santa would squint as he flew over my street. And let me tell you, these batteries DELIVER. The moment I charged them up, I swear I heard a faint choir of angels (possibly my imagination, possibly the fairy lights themselves humming with excitement). I loaded them into my lights and… BOOM. The glow. The shimmer. The sheer *luminosity* of it all. My house didn’t just sparkle, it achieved a level of brightness that could guide ships into harbour. I wrapped the first set around my little red-berry-bearing tree. Hours passed. Still glowing. Night turned into morning. Still glowing. Neighbourhood dogs barked at the suspiciously constant light. STILL. GLOWING. Then I used them for the fairy lights on my door cover. Same story. Hours and hours of uninterrupted festive brilliance. Meanwhile, my neighbours frantically battled with plug sockets, overloaded extension leads, and timers that only seem to work when Mercury is in retrograde. Not me. Oh no. I stroll past my lights like a smug festive wizard, knowing full well that my energy supply is infinite. I have more rechargeable batteries. SO many more. I have become the Christmas equivalent of someone hoarding gold bullion in a bunker. The neighbours keep asking, “How are yours STILL on?” I just smile mysteriously, like I’ve made a deal with the Elf King. But really, it’s these batteries. These beautiful, unstoppable, long-lasting, Christmas-saving batteries. If these things ever go out, it’ll be because I took them out myself, not because they gave up. These batteries don’t give up. They PUSH THROUGH. They WORK OVERTIME. They carry the entire festive season on their tiny cylindrical shoulders. Buy them. Charge them. Illuminate your life like a glorious holiday beacon. **Hours and hours of Christmas lights? Try days**

I recently picked up the Amazon Basics 12-Pack of rechargeable AA batteries, and let me tell you, these little guys have been a game changer for me! First off, it’s super convenient to have a whole pack, especially since I seem to have a million gadgets that need batteries. From remote controls to my kid's toys, I never have to worry about running out. The batteries charge fairly quickly, and I've found they hold their charge pretty well. I’ve used them in various devices, and they perform just as good as the alkaline ones I used to buy. Plus, it's great knowing I'm being a bit more eco-friendly by using rechargeable batteries. What I really appreciate is how cost-effective they are in the long run. While the initial purchase felt like a bit of an investment, I can already see the savings since I’m no longer constantly buying disposables. They also come with a nice little charging station if you don't already have one, which is a nice touch. Overall, I'd say if you’re tired of buying disposable batteries and want something reliable, this 12-pack is worth considering. They’ve definitely made my life easier!

I shall be buying more of these rechargeable batteries. At present, I'm using them to power outside lights that my wife insists need to be on - despite them being solar powered and there being insufficient sunlight to keep them charged. Fortunately, the lights have removable rechargeable batteries so I'm whacking these AmazonBasics batteries in them every 3-4 days to keep her happy. As any man knows, this is essential if you want to do anything that doesn't involve a constant whining sound in your ears. They charge quickly and they appear to have good life. They probably have a better life than I would if I was to stop placing them in the exterior lights. Come to think of it, such a risk isn't worth taking. I would be safer taking a long walk off a short pier, hang-gliding in the Himalaya's or hitching a ride on the back of Lewis Hamilton's F1 car at 210 mph and asking Pastor Maldonado to return to F1 and try to overtake us without actually hitting us. They're a rather neat grey and lime green colour. If you don't like lime green, tough. I think it is a perfectly nice colour that reflects environmental concern, something that won't be at the top of the list when you come to dispose of any battery in this day and age. Your local council will probably insist you place the batteries in a silly bag in order for them to take them, so you'll inevitably just throw them into the general waste bin. Woody Woodpecker - whatever happened to him? I miss him. But I digress... I wasn't sure about buying these batteries and almost opted for another brand (a better known brand where batteries are concerned). However, I then realised that I was probably going to do little but subsidise their next ridiculous "Bunny Rabbit" advertisement on TV and I couldn't live with the thought of that. The thing is, I've nothing against that bunny but it is wearing a bit thin now. How many times can you advertise batteries with a toy bunny and keep the interest of people? A year? 3 years? But 15-20 years? It must have been on TV that long now? Everyone knows a normal bunny would have long since died, popped its clogs and gone to bunny heaven. Don't try using these batteries to power your Tesla. They're unlikely to work. For everything else, they do the job. Stop wasting your time reading this and get them bought. Before you do, spare a thought for Woody Woodpecker. He's probably redundant, or even dead.

Have used these batteries for a while now and they're initially pretty good. I would say they get nowhere near the quoted 400 cycles before becoming useless. Had a good few refuse to charge in the charger now and are useless.

These Amazon Basics rechargeable AA batteries are excellent. I’ve ordered them multiple times now, and they’ve been consistently reliable every time. The 2400 mAh capacity lasts a long time, whether I’m using them in controllers, toys, cameras, or household devices, and they hold their charge well between uses. They recharge quickly, perform just as well as more expensive brands, and have saved me a lot of money over time. I also appreciate the convenience of the 16-pack — it’s great to always have spares ready to go. Overall, these are dependable, high-quality rechargeable batteries at a great price. I’ll definitely continue reordering them and highly recommend them to anyone looking for long-lasting rechargeables.

The battery seems okay, but the size for this AA battery, not sure had it got 1mm extra bulk, it seems to not fit normal UM-3 slot. I had to massage it in. Will see.

Rapport qualité prix au top, longue durée selon l'utilisation.

..., deutlich besser als die meisten, die ein gutes Stück teuerer sind. Eines vorneweg - bei den "Sternchen", die man da setzen sollte, steht ua. auch "Fernbedienung" - ich rate euch dringend, von der Verwendung dieser Akkus ( oder Akkus im Allgemeinen ) in Ferbedienungen, Wetterstationen, Wanduhren und/oder Solarlampen ab. Warum ??? - die werden da drin, schlicht und ergreifend vergessen - und gerade diese Gerätchen, haben keinerlei Akkuüberwachung - wenn da der Akku alle ist, merkt man erst, wenn der "Kram" nicht mehr funktioniert - dann ist es allerdings viel zu spät, für den betreffenden Akku ------ der ist in der Tiefstentladung - und wird sich, mit an Sicherheit grenzender Wahrscheinlichkeit, nicht mehr aufladen lassen - der betreffende Akku ist nur noch zum Entsorgen gut. Ansonsten - Die stehen in den Telefonhörern DEUTLICH!!!!!! besser/länger, als die eigentlich dafür entwickelten DECT-Akkus. Ich hab die, als 850mA-AAA ( gleicher Akku - Amazon Basics ) in einem Uralt-Sinus mit vier Hörern, von der Telekom drin - schon eine gute Zeit länger, als die teuer bezahlten DECT-Akkus, von einem bekannten Markenhersteller mit Pa... am Anfang - sogar die ENEL... von denen, die normalerweise, nie länger als ein Jahr "mitgemacht" hatten. Ich kann nur eines sagen - diese Akkus hier sind, auch fürs Telefon, absolut empfehlenswert - und natürlich auch deutlich günstiger, als die "Markenakkus", die nichts taugten. Eines ist sicher - wenn die hier anfangen "den Geist aufzugeben" - sofort die Gleichen wieder - gerade fürs Telefon - die Besten, die ich nach den Originalen, jemals hatte. Muss noch was anhängen, die Rezension mit diesen "Kurvenbildern" betreffend. Der Kunde unterliegt einem Denkfehler, was die Entladung dieser Akkus betrifft - auf den Bilder ist deutlich erkennbar, daß der Entladestrom 2A/2000mA ist - das ist für solche Akkus eindeutig zu hoch, sogar viel zu hoch. Alle Fachbücher sagen - der Ladestrom für Standart NMH/NC-Akkus soll 1.C nicht übersteigen - bedeutet 1/10tel seiner Kpazität als Ladestrom über 10 Stunden - bei jedem 10ten Ladezyklus, wird über 14 Stunden nachgeladen ------------- diese Fachbücher sagen aber auch, der maximale Entladestrom eines Standart Nickel-Akkus soll 2.C, also 2/10tel, nicht übersteigen - und diese hier sind Standart - bedeutet bei einem 2400mA-Akku, nicht mehr als 480mA - der Akku wirds dir nicht danken. Es gibt sog. Hochstromakkus - die sind entladbar bis max. 4.C - wären dann max. 960mA - keinesfalls 2000. Mein ALC8500-Ladegerät, daß auch so schöne Kurven "malt", stelle ich tatsächlich auf die vorgegebenen Werte beim Refreshen ein - und ich hab CONRAD-Hausmarkeakkus, 500mA, die sind gut und gerne 15-20 Jahre alt - die tuns immer noch - und nicht mal schlecht. Lieber Kunde - stell deinen Entladestrom runter - dann hast du länger Freude an deinen Akkus - oder - schau mal in die Bücher - hilft oft. Noch was liebe Leute - JEDER, aber auch tatsächlich JEDER!!!!!!! neue Akku, muss vor der ersten Inbetriebnahme nachgeladen werden - schlicht und ergreifend deshalb - kein Verkäufer kann euch sagen, wie lange der Akku im Regal gelegen hat, bevor er zum Kunden geht - und da ALLE !!! Akkus, mehr oder weniger, einer sog. Selbstentladungsrate unterliegen, kann niemand sagen, wie hoch die tatsächliche Kapazität des Akkus ist - ihr werdet euch, auch einen neuen Akku, ohne Nachladung, garantiert ruinieren - das gleich gillt natürlich/selbstverständlich auch für Geräte mit fest verbautem Akku - aus vorgenannten Gründen ) - und - vorgeladen, wie bei manchen Akkus beschrieben, bedeutet nicht, daß der vollgeladen bei euch ankommt, sondern lediglich, daß der Akku schon einmal geladen war, um seine Funktionsfähigkeit zu testen. Kurz was zum Thema Solarlampen - klar/selbstverständlich sind in Solarlampen Akkus drin, meist sogar Nickel-Akkus ( NC, NMH ) - aber - die haben Kapazitäten nur etwa 400 bis 600mA - einen 2400mA-Akku schafft die kleine Solarzelle nie im Leben, über den Tag vollzuladen - folglich wird immer, Abends, ein teilgeladener Akku in Betrieb genommen - das macht einer von denen hier, wenns gut geht 14Tage bis drei Wochen mit - dann ist Ende - "echte" Solarzellenakkus haben auch einen anderen inneren Aufbau, ähnlich einem DECT-Akku - die "verkraften" Teil-/Tiefentladungen deutlich besser, als zb. die hier - und - in einem Akkupack ( Reihen-/Parallelschaltung ), niemals nur einen einzelnen Akku wechseln - die Alten ziehen den Neuen, wegen des sog. Ladungsausgleichs immer leer - da macht ein Neuer es auch nicht sehr lange ---- wenn, immer alle Akkus wechseln - ist sehr wichtig !!!!!! ...und noch einen Tip - kommt bitte nur nicht auf die Idee, in einem "schnurlosen" Hörer, einfach viel "dickere/grössere" Akkus, als die Originalen reinzutun, nur weil man dann vermeintlich, ja auch länger Telefonieren kann/könnte - die Ladeschalen, für diese "Schnurlosen", sind nur für diese Originalgrösse berechnet - einen "Dicken" schaffen die nicht komplett zu Laden ( die liefern den nötigen Ladestrom einfach nicht - evtl. nach einigen Tagen, dann aber, ohne Telefonat/zu Telefonieren ) ---- 50mA sind da nicht so schlimm - aber, einen zb. 850mA-Akku, gegen einen 2400mA-Akku auszutauschen, wird nur kurzzeitig funktionieren - dann werft ihr diesen 2400mA-Akku auch weg - da seeeeeeeeehr tiefe Tiefentladung - Akku "ermordet" - der tuts nicht einmal mehr, in zb. einer Wanduhr ;-).

I was going through batteries like water for kids toys. These have been great in both AA and AAA. Very easily charged and good life on them once charged. It has saved me a lot compared to constantly buying batteries.

Amazon Basics AA Rechargeable Batteries (2400 mAh) – Real Capacity Test Results I ran a full analysis cycle on 8 cells using an ISDT N8-series smart charger at a 0.5A charge/discharge rate. Unfortunately 4 of the 12 cells were accidentally thrown out with the broken toy they were in so I couldn’t test those. Here are the actual measured results after initial break-in and a few months of normal use in kids toys and various gadgets: Capacity Results (mAh): - 3001 - 2687 - 3001 - 2658 - 2639 - 2625 - 2649 - 2698 Average Capacity: 2700 mAh Rated Capacity: 2400 mAh Internal Resistance (mΩ): - Range: 124 mΩ – 200 mΩ Key Takeaways: • All 8 cells tested at or above their rated 2400 mAh capacity • Two cells measured around 3000 mAh, which is significantly above spec (likely inflated slightly by the lower 0.5A test rate, but still impressive) • Most cells clustered tightly between 2625–2700 mAh, showing good consistency • Internal resistance varied from 124–200 mΩ, which is decent but not premium-tier low What this means for real-world use: These are solid mid-to-high performance NiMH cells: - Great for moderate to high-drain devices (controllers, cameras, etc.) - Not quite as consistent as premium Japanese made brands, but very close considering the price - One higher-resistance cell (~200 mΩ) may perform slightly worse under heavy load and prematurely wear out. Lower resistance means less voltage sag under heavy load. Pros: - Exceeds rated capacity across the board - Good consistency between most cells - Good value for the price Cons: - Internal resistance spread is noticeable - Not all cells are perfectly matched for High-drain use Final Verdict: 4.5 / 5 (Rated five stars because you can’t give a half star rating, close enough however): For the price, these perform above expectations. If you’re willing to match cells based on performance (capacity + internal resistance), you can get excellent results comparable to more expensive brands. Testing Note: Results were obtained using a 0.5A analysis cycle, which can slightly inflate capacity readings compared to higher-drain real-world use. Not an appreciable difference however in actual usage. Testing Equipment - ISDT N8 Series Smart Charger Please note: Don’t be disappointed if brand new cells don’t meet their rated capacity out of the box. NimH rechargeable batteries have a break-in period when new. This is usually 3-5 full charge/discharge cycles (for premium Japanese-made cells around 2 charge/discharge cycles). A good smart charger can do this for you. It can take several hours or they will break-in themselves over time with normal usage but their performance will increase after break-in.
