Eneloop Panasonic BK-3MCCA10FA AA 2100 Cycle Ni-MH Pre-Charged Rechargeable Batteries, 10-Battery Pack

Love these for my battery operated indoor candles. Save a ton of money over time. They are reliable and last a long time. Fast charge with the Panasonic charger.

These are amazing rechargeable batteries. I've heard from many that they last a long time, and the casing on them already feels much better quality than your typical non-rechargeable AA/AAA battery.They work in all the devices I've normally been putting traditional AA batteries in, they're the same size and everything, kind of the point of the AA standard, and they work well.If you need rechargeable batteries, these will definitely be worth the money.

Great batteries so far, seem to have the same power of a standard AA but rechargeable. The charger can hold both AA and AAA so it cuts down on excess items.

Love the Eneloop rechargeable batteries. We have them in AAA and AA sizes in many devices around the house. They keep their charge even when stored for a long (1 year +) timeframe between uses. NO LEAKAGE when stored in electronic doodads, unlike the old alkaline batteries, these NiMH batteries have not leaked even in devices that sat around unused for more than a year. PSA: it's always a good idea to remove batteries from electronic devices that are not going to be used for an extended timeframe.

Best rechargeable batteries we've used, charge fast enough and definitely last way longer than the Amazon basics brand! Like a 3 to 1 difference in charge duration.

Eneloop rechargeable batteries are the best. They are our go-to batteries. They are keep their charge and last four years.

I've been using Eneloop cells rechargeables since they were Sanyo. They seem to last forever and of the many (over 100) that I've used, none have leaked or failed. I still have some from 2012 that I use regularly (I date each cell so that I only use like-dated cells in any application) that work fine.

Just a heads-up: While the packaging shows the older BK-3MCCA model, the batteries I received in the package are actually newer 5th generation BK-3MCDA cells. That’s a plus; these are the latest version. In simple terms, you get slightly more capacity, voltage stability, quality control, and output.Cons:One caveat: the 2100 charge cycle claim is a bit misleading. That number is based on a generous IEC lab testing. In real-world use (or a more stringent IEC test), you should expect closer to 600 cycles. This is shown on the packaging. I wish Panasonic was a lot more transparent about this.Don’t expect these to power high-drain devices like camera flashes, RC glow igniters, or air pumps very well. For that, you’ll want Eneloop Pro cells, which are designed for heavy draw. These cells don't perform well in camera flashes in my experience.Pros:These Eneloop AA batteries are excellent for midrange power applications like smart locks, wall clocks, and flashlights. I’ve also tested them in sub-zero temperatures outside my house down to -15°C (about 5°F), and they still perform reliably, which makes them great for outdoor winter use. Much better than cheap alkaline batteries.The batteries are genuine Eneloops, with proper date codes embossed on the cells to view manufacturing date. No issues with authenticity. You can see in the provided photos how genuine cell date codes are supposed to look like.Overall, a solid buy for typical household and low-to-mid-drain gadgets. Just make sure you understand what your needs are and get what suits you best.
