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 :-) Read more

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. Read more

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! Read more

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! Read more

Everything is good. My only complaint is the batteries arrived on the date that I did not expect. I bought on 11/17 and estimated delivery date changed a few times and then moved to 11/29. The package was delivered on 11/28 when I was not home. Luckily, I am living in a good and friendly neighborhood so everything is fine. I hope the estimated time works better. Read more

A much better value than the black 'Pro' version. Almost the same capacity and 4X more charge cycle life. It's a good idea to mark the month/year on them when they arrive to know their age. Read more

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. Read more
