Amazonベーシック 充電池 単4形 ニッケル水素電池 24本 850mAh 1.2V くり返し最大500回 充電済

何も問題ないですよ自己放電も普通で放置していても使う時に問題ないです

可もなく不可もなく。安くて良いと思いますが長期使用しないとなかなか評価出来ないですね

特に問題なく使用できます。

コスパは最高ですが、パナとか日本メーカーの電池よりも大きいので、入れるとき若干窮屈です。

Amazonブランドなので安心して買えるのは良い

充電もちは、普通です。

There're several brands I keep going back to for rechargeable batteries, and Amazon Basics is one of them. The other two are Eneloops and Ikea Laddas. There are claims some of them are relabels of each other, I can't say for sure but all of them have worked reliably. They're also all very easy to procure, meaning it's easy to use 3-4 of the same batteries in a device rather than having to mix and match. They fit in standard battery chargers. There's nothing wrong with them other than the usual issue with the sudden voltage drop compared to alkaline batteries. Some devices like smart door locks recommend you use alkaline batteries so low voltage detection works to alert you before a critical device runs out of battery. Since lithium ion batteries hold the voltage longer before a steeper drop, your devices tend to die more suddenly. But for kids toys that drain battery like crazy, it's hard to go wrong with these rechargeable batteries. I also like how you can find different counts for each battery size with Amazon Basics, so you buy exactly how much you need. There's not a huge discount for buying more, as is often the case in Japan, so just buy how much you need. Great for kid's toys and remote controls mostly, many toys seem to prefer AAA over AA nowadays.

安定の使い易さ。 他社製品より値段を気にせずストック出来る。

Recently purchased the Amazon Basics 12-Pack Rechargeable AAA NiMH Performance Batteries, and I must say, I am thoroughly impressed with their performance and value for money. These batteries have become an essential part of my household, and here's why: - Love the long-Lasting Power: Has a 800 mAh capacity of these batteries provides ample power for a variety of devices. Whether I'm using them in remote controls, wireless mice, or small electronic gadgets, I am getting consistent reliable and long-lasting performance. - Quick Recharge: These batteries recharge quickly, which is a huge convenience. I appreciate not having to wait around for hours to get my devices up and running again. It's a great time-saver! - Durable and Reliable: For the most part, as brand name Amazon Basics I have kinda been skeptical, but the quality, with these batteries are great Built to last and can withstand multiple charge cycles without losing their capacity or efficiency. This saves me money in the long run and reduces waste. - Environmentally Friendly: I love that I can reduce my environmental footprint by using rechargeable batteries. It's a small but meaningful step towards sustainability, and these batteries allow me to do that without sacrificing performance. Hey, at least I am trying to do my little bit for the planet. - Economical Choice: 12-pack is a fantastic deal for the price. Considering the quality and longevity of these batteries, they are an economical choice compared to disposable ones. I've saved a significant amount of money since making the switch. Got high hopes for Amazon Basics 12-Pack Rechargeable AAA NiMH Performance Batteries . I highly recommend these batteries to anyone in need of AAA rechargeables – they won't disappoint! Off now, to look at their AA offerings.

Amazon Basics AAA Rechargeable Batteries (850 mAh, NiMH) — Tested Capacity, Performance & Matching Results I tested a full 12-pack of these AAA rechargeable NiMH batteries after a couple months of normal use in kids toys and various gadgets using a charge/discharge/charge analysis cycle, and the results were consistently strong, well above the rated capacity, with only one weaker outlier. Test Setup * ISDT N8 Series smart battery charger * Full analysis cycle (charge → discharge → recharge) * 0.3A charge/discharge rate * 0.90V cutoff voltage * Temperature range: 28°C – 33°C Measured Results * Average Capacity: 1,079 mAh * Highest: 1,171 mAh * Lowest: 964 mAh All cells exceeded the rated 850 mAh capacity, with most landing comfortably above 1,100 mAh, which is excellent performance for AAA NiMH batteries in this price range. Internal Resistance & Performance * Average: 193 mΩ * Most cells: 180–200 mΩ * One outlier: higher resistance, lowest capacity Lower internal resistance helps with performance meaning less voltage sag in high-drain devices like controllers, camera accessories, and other electronics. Cell Matching Results: After testing, I grouped the batteries by performance: * Top tier (7 cells): high capacity, closely matched * Mid tier (4 cells): slightly lower capacity but still good * 1 outlier: lower capacity and higher resistance This is typical for budget rechargeable batteries but still allows for multiple well-matched sets. What Stands Out * Consistently exceeds rated capacity * Good overall cell matching * Only one weak cell in the pack * Works well for both high-drain and everyday devices Final Thoughts These Amazon Basics AAA rechargeable batteries are a solid high-capacity option at a very reasonable price. With basic matching and rotation, they can deliver performance close to more expensive brands. The cons to this being that this is effort you generally don’t have to expend with more expensive premium Japanese made cells. However, if the cost savings are worth it to you these are a great value for the money and outperform a lot of the other Chinese-made budget cells. Some of whom wildly overstate their actual capacity. Rating: 4.5 / 5 (Can’t give half a star Amazon rating. Hence the five star rating) Please note: All NiMH rechargeable batteries have a break-in period when new. This is usually 3-5 full charge/discharge cycles (premium low self discharge Japanese-made cells generally only need one or two cycles). A good smart charger with a “refresh” or “activation” function can do this for you (it can take several hours) or it will naturally happen over time as you use them. This just means that capacity will increase after break-in so rechargeable batteries aren’t necessarily defective if they don’t meet their rated capacity straight out of the package. Why grouping similar performing batteries, if possible, makes a difference in real-world performance. When using rechargeable batteries in devices that use multiple batteries like controllers the load is shared by both batteries. Pairing a strong cell with a higher capacity and lower resistance with a weaker lower capacity higher resistance cell means the weaker cell is going to deplete and drop voltage faster. The stronger cell ends up shouldering more of the workload. This all means you get less time between recharges. None of this, of course, is strictly necessary, but if possible analyzing and grouping together similar performing batteries will increase their lifespans and give you more usage time between recharges. Once again not strictly necessary but something to note.

Son muy buenas, su relación calidad precio valen la pena. Se recargan rápido.

Good price

Pilas buenísimas, funcionan perfecto en mi cargador marca "Energizer" y la batería les dura bastante, las compré para mi control de videojuegos y demás controles del hogar, les dura meses la carga.
