Eneloop Panasonic BK-4MCCA10FA AAA 2100 Cycle Ni-MH Pre-Charged Rechargeable Batteries, 10-Battery Pack

I recently switched to the Eneloop Panasonic BK-4MCCA10FA rechargeable batteries, and they truly exceeded my expectations. These batteries deliver consistent performance across a variety of devices, holding their charge for impressively long periods. I appreciate their robust build quality and quick recharge time, making them a reliable option for daily use. Plus, knowing they’re eco-friendly gives me extra peace of mind. Overall, I highly recommend these batteries to anyone seeking long-lasting, dependable power solutions.

Eneloops are some of the best rechargeable batteries ever made! If you want to make the intelligent choice, switch to rechargeables but don't choose a brand that makes other batteries, they have no interest in their rechargeables working well b/c they sell non-rechargeables as their main business. Hint: the 2 main battery manufacturers' rechargeables are pure TRASH in my opinion!Panasonic may make non-rechargeables but it's a small part of their market. I have AA Panasonic rechargeable batteries that are over 20 years old and still hold a charge. The Eneloops show similar quality and longevity.If you want to know one thing you can do that will save you money in the long run AND help the environment, move to rechargeables and choose Eneloop. But don't just take my word for it, public opinion agrees. These are a solid investment.

Excellent rechargeable batteries! I’ve used these for the last 25 years and the ones purchased back then still recharge and work beautifully. Just purchased some more AAA for 3 air conditioner units. Highly recommended.

Way, way, way cheaper than buying disposables! Last for years. In 10 years, I think I've only had 4 go bad. Extremely high quality, made in Japan (not China!). Better for the environment, better for your wallet (in long term), so these are a no-brainer.

Love that they came precharged. I already had a charger, so this worked out well and the 10 pack was the cheapest at the time per battery.

These Eneloops are built to last. The quality is excellent, and they’ve consistently outperformed other rechargeable brands I’ve used. Long-lasting charge, solid construction, and you can feel the difference. Panasonic knows what they’re doing—this is the kind of product you just set and forget because it works.Battery life:10/10

Yes, these batteries work but when I put them in a PC mouse and they didn't work. I played around with them and got them to work but not reliably. I cannot explain why they won't work in all battery compartments but I suspect it has something to do with the way the positive tip is set into the battery case. The positive terminal wasn't making a secure connection. They will work in most battery compartments but not all.

I picked these batteries because I've used the AA size and have found them to be the best NiMH batteries I've tried. The AA's hold a charge well, even in storage and last a long time. I have no reason to believe these won't be every bit as good as they are, but if I do find any problems I will post an update to this review. Again, based on my experience with the AA's from this company, they are an excellent value for the price.
