Eneloop Panasonic BK-3MCCA8BA AA 2100 Cycle Ni-MH Pre-Charged Rechargeable Batteries, 8-Battery Pack

I have used these batteries in a couple digital door locks [for public areas in an apartment building], remote controls, mice/keyboards, flashlights - so they get a lot of use. I've been using them for years with very good results. In fact, the first pack I bought (four years ago?) is still in active [daily] service. They seem to last longer between charges, for these types of applications, and their lifespan has been *much* better than others (like the Amazon Basics green/black rechargeable batteries or any of the off brand Chinese batteries that I've used). A friend with a some RC toys says that they don't have quite the 'punch' that the high power ones do. But, we've both noticed that these don't loose as much power on the shelf and don't need to be replaced anywhere near as often [and my computer keyboard and mouse don't care]. For things that need a lot of short term power (like RC toys) the 'high power' versions will probably be more fun but, be warned, you will be replacing those very, very, very often. This seems to be true of the 'boring' applications as well - It gets very expensive. For what I use them for, these batteries really do the job. They have been a incredible value for the money in comparison to any of the other ones that I've tried. Fall 2022 follow-up ------------------------------ I wrote the original review years ago and have to say, nothing has changed. I'm still using the 'white wrapper' batteries in a bunch of devices: door locks, LED candles, keyboards, mice (low power draw stuff) and they work great. Batteries provide good time between charges and, most importantly to me, they just keep working (years now). I bought more, earlier this year for additional devices - got a large pack with replacements in mind - but I haven't had to replace a single one. The white label batteries work great in these sorts of devices - highly recommended :-)

High quality rechargeable batteries. Still working after 5 years. Can be left in equipment for a long time. Batteries won’t leak chemical. Cheap batteries including Duracell batteries leak chemical when left inside equipment or toy for long time.

These are fantastic rechargeable batteries and will save you a lot of money, I've had them over 2 years and they still work great and have excellent capacity and charge quickly. Using these will also help the environment by reducing the number of batteries that are thrown away each year. Definitely recommended!

Last long for playing xbox, really good and manageable to use day to day.

Great batteries that last a long time on one charge. I was buying EBL batteries for our landscape lights and they would last 2 nights without sun and these Eneloop Panasonic batteries can go 3 or 4 nights without sun. Definitely glad I found them and tried them.

I buy these batteries for flashlights, my mouse and other small electronics. They last about as long as a standard Duracell or Energizer alkaline. They cost a lot less because they are reusable - and that goes a long way for my bluetooth mouse, small flashlights and other electronics I'm always using. I enjoy having rechargeable batteries, instead of constantly buying whatever is on sale when I go shopping. Panasonic has always been a reliable battery for me. I prefer the more expensive Eneloop PRO batteries - they are a dark grey/black color and are visually different. I prefer them because they last longer and perform better in photography flashes, wireless microphones and stuff that uses a little extra juice. So, there you have it. They're great batteries. I'm sure there are generic brands that work just as well, however, I've used Eneloops professionally and they have been very reliable under perpetual use. These batteries (rated at 2100) are perfectly fine and are a great value - but if you're using them professionally, but the next step up from Panasonic and a charger that will charge 8+ at a time.

The Eneloop Panasonic BK-3MCCA8BA AA Rechargeable Batteries are by far the best rechargeable batteries I’ve ever used. Right out of the package, they come pre-charged and ready to use, which is super convenient. Their low self-discharge rate means they hold power for a long time when not in use—perfect for devices that sit idle for weeks or months. With up to 2100 recharge cycles, these batteries provide incredible long-term value, making them a cost-effective and eco-friendly alternative to disposable batteries. I use them in a variety of devices, from remotes and flashlights to cameras and gaming controllers, and they consistently deliver reliable, steady power. Another great feature is their ability to perform well in different temperatures, which makes them perfect for both indoor and outdoor use. I’ve noticed that they maintain their charge exceptionally well even after extended use, and they don’t suffer from the memory effect that some other rechargeable batteries have. Overall, the Eneloop AA batteries are a top-tier choice for anyone looking for high-quality, long-lasting, and eco-friendly rechargeable batteries. Highly recommended!

Very good

There are so many positive reviews for these eneloop batteries there is only so much I can say about them that has not already been said. After using these batteries for a few months I can honestly say I'll never buy Duracell, Energizer or other rechargeable again until they adopt the chemistry, performance and quality control of the eneloop standard. They are leaps and bounds ahead of everyone else. Straight out of the pack the batteries were ready for use and charged.... but not to full capacity (mine were about 75%). When I did charge them I was pleasantly surprised, my battery analyzer showed each cell exceeded it rated capacity of 2000mAh and held over 2200mAh (discharge capacity). The best thing you can take away from the eneloops is that they are really geared for real world usage... meaning that you can charge them up months in advance and the Low Self Discharge rate allows them to hold that charge, so they are always fully charged and ready when you need them. I should also mention that you can use these batteries in lower temperatures (-20c, -4f) than typical NiMh and they are much more tolerant to partial charges or "top ups" than other AA batteries. All of this is important for me as the rest of my family does not care for or understand proper battery cycling or maintenance, so having these batteries which are easier to maintain and much harder for them to kill (murder) is essential to having batteries that last and outperform for a very very long time. I hope you find my review helpful!

Las uso para mis controles de xbox one, que usualmente utilizo con el headset conectado que con baterías anteriores había notado que se descargaban muy rápido. Con estás no he medido el tiempo porque más bien he perdido la cuenta de su duración, pero seguro es más de 15 horas de juego continuo. Único punto no tan bueno es que tardan unas 5 horas en cargar un par de las baterías y según entiendo el doble de tiempo por las 4 al mismo tiempo, por lo que estoy considerando comprar otras 4 baterías para tener de repuesto cuando se agoten unas y no tener que esperar tanto.

While re-charging with the Panasonic Quick Charger, I found these Panasonic batteries are the best available on the market. The price is reasonable and for the long use, it costs almost zero.
