Amazonベーシック 充電池 単3形 ニッケル水素電池 12本 2400mAh 1.2V くり返し最大400回 充電済

コスパがいいので使えなくなってもなっても気にならない。色々使いまわしてます。

電池の性能については申し分ないと思います。全長は変わらないものの、プラス極の頭が低く、物によっては端子に届かない事があります。故障かと思って焦る前に一度電池を取替えてみることをおすすめします。

充電式ニッケル電池はずっとパナ◯ニックを使っていましたが、最近とても価格が上がって買えなくなりました。試しにこちらの製品を購入しましたが、パ◯製品と何ら遜色ありません。若干出力電圧が低いようですが、実用的には全く問題ありません。今後は随時切り替えます。

1.使用感 他社と比べると、タイトルのように電圧低下率が大きく、長時間使用には向かない。値段なり。 具体的には、エネ〇〇プの1/2程度の印象。 2.良かったところ コスパが良いところ 3.改善が必要なところ 電圧低下率を小さくしてほしい。 4.リピしたいか

合わない危惧もある。

普通に充電出来ました。使用回数がまだまだ少ないので、長持ち（充電回数）の度合いは分かりません。

防災用に購入

とても、良いです。

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.

Ho scelto queste batterie perché avevo bisogno di una soluzione economica e ricaricabile per telecomandi, giocattoli e dispositivi elettronici domestici. Prima impressione Appena tolte dalla confezione, le batterie risultano compatte e ben finite, con scritte chiare che indicano capacità e tensione. Essendo precaricate, sono subito pronte all’uso, il che è comodo per chi non vuole aspettare la prima ricarica. Uso nella vita quotidiana Le utilizzo in telecomandi, mouse wireless e piccoli giocattoli. La durata è buona, e il fatto che possano essere ricaricate fino a 400 volte le rende un investimento conveniente nel tempo. La capacità di 2400 mAh permette di avere prestazioni stabili anche con dispositivi che richiedono corrente moderata. Cosa funziona bene Precaricate e pronte all’uso, comode subito. Alta capacità (2400 mAh) per lunga durata nei dispositivi quotidiani. Ricaricabili fino a 400 volte, molto conveniente nel tempo. Funzionano bene in dispositivi che richiedono corrente costante. Buon rapporto qualità-prezzo per una confezione da 8 batterie. Cosa convince meno Non adatte per dispositivi ad alto consumo continuo (come fotocamere professionali o flash), dove durano meno. Richiedono un caricatore NiMH appropriato per ricariche ottimali. Essendo AA, limitate a dispositivi compatibili con questa misura standard. Conclusione Le batterie ricaricabili Amazon Basics AA sono una scelta pratica ed economica per uso domestico, perfette per telecomandi, giocattoli e piccoli apparecchi elettronici. Offrono lunga durata e facilità d’uso, ma non sono ideali per dispositivi ad altissimo consumo.

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.

Ok, ale rzeczywiście średnica baterii trochę większa (grubsza) niż standard, więc nie wszędzie będą pasować.

I decided to switch properly to rechargeable batteries after realising how many disposables we were getting through every year. Between Xbox controllers, remotes, wireless mouse, children’s toys and the odd torch during power cuts, it was adding up. I went for this 12-pack of Amazon Basics 2400 mAh AAs because the price per battery was very reasonable, especially compared to big-name brands. The fact they arrive pre-charged is genuinely useful. I was able to put them straight into a controller and a bedside lamp without waiting around for a full charge first. That convenience makes a difference. In terms of compatibility, they’ve worked perfectly in everything I’ve tried — standard AA sizing means they slot straight into controllers, torches, fairy lights, clocks and cameras without any fitting issues. They sit snugly in the battery compartments and make proper contact first time. Performance has been consistently strong. In higher-drain devices like game controllers and LED torches, they hold up well. Brightness in torches and battery-powered lights has been steady and comparable to good disposable batteries — no dim, weak glow or early fade. Even as they start to run lower, the power output feels stable rather than dropping off suddenly. The 2400 mAh capacity is noticeable. They last longer than older rechargeables I’ve owned, especially in devices that get regular use. They also hold charge well when sitting unused. I’ve had a few stored for a couple of weeks and they still had plenty of power left. As for weight, they feel solid but not overly heavy. In hand they have that reassuring density you’d expect from a decent rechargeable battery, but they don’t make controllers or smaller devices feel bulky or unbalanced. Long term, the value is where these really make sense. Being able to recharge them hundreds of times will easily outweigh the initial cost, and it’s far better than constantly throwing away single-use batteries. Overall, reliable, widely compatible, steady brightness output and excellent value for money. These have become my default choice and I wouldn’t go back to disposables now.
