BK-4MCCA16FA eneloop AAA 2100 Cycle Ni-MH Pre-Charged Rechargeable Batteries, 16 Pack

We invested in Eneloop batteries over 15 years ago and they hold up very well. We use them in everything and they last a long time. As soon as something that needs batteries stops functioning, I swap out thr eneloops and put the old ones in the charger then the next morning I move them to the drawer. They hold their charge until the next time I need them. I recommend these batteries to everyone.

I won’t use AAA alkaline batteries because of leak risk, so all my mine are either eneloop or Energizer Ultimate Lithium. Eneloops fit many of my needs, and as mine were all 10-16 years old (though still worked), I finally decided to replace them. Since the manufacture date is now the same on all, I don’t have to think about grouping them by generation or date made. These Gen. 5 have 850 max. mAh (800 min.), hold a 70% charge for 10 years, and can be recharged 2100x. The only downside is they shouldn't be used in airtight devices in case they get over discharged and vent hydrogen gas. So that leaves out things that are IP rated as dust and/or water tight, like many flashlights. But since that's true of all NiMH, these are still 5 stars.

Pro: As part of Peer Product Review, I tested Panasonic Eneloop rechargeable batteries and have been consistently impressed. They last an incredibly long time, and I’ve never had a single battery fail me in over 10 years of use. I’ve used hundreds of AA and AAA Eneloop batteries to power various electronic gadgets, and they’ve proven to be exceptionally reliable and durable. Con: The price is a bit high compared to other rechargeable batteries, and a slight price reduction would make these an unbeatable choice. Summary: Panasonic Eneloop rechargeable batteries are an outstanding investment for anyone seeking long-lasting and reliable power solutions. They have served me well for over a decade, powering a wide range of gadgets without fail. Although slightly pricey, their durability and performance make them well worth it. Highly recommend these for anyone who values quality and longevity!

Best rechargeable batteries on the planet right now reasonably priced and they do exactly what they say they do I had some with this. I forgot about left in a plastic bin for 2 years and they were right. It still had about 70% of its power left on it. I bought multiple different brands of rechargeable batteries and when they're left in their packages for too long and then you try to charge them a few years later. Even though they're brand new and you haven't opened them up, they don't last very long and the charge depletes itself almost immediately. By the next day they've lost 20 to 30% of their charge. These are different. These are the best batteries you could buy rechargeable wise. They're worth it. I made the mistake of buying aaa's which I didn't need but I decided to keep them because of their reliability in case I ever needed them one day and since they last that long in storage without needing to be recharged I decided to keep it. It just wasn't worth my time trying to return them. These are great though. Five stars all around. If you want the best rechargeable batteries currently on the market these are them. They do everything that they claim. You can't go wrong with these

Works great but need to remember that when the battery gets weak it just shuts off compare to the carbon type.

These are in my opinion the best rechargeable batteries

These batteries work great, even after many recharges. Only downside is they occasionally don't work or fit correctly in some products when a regular Duracell or Energizer work just fine.

These Eneloop rechargeable batteries are the best I have ever bought. Some of them have been charged 50+ times and still perform a good long time. I have tried Energizer and Amazon Basics, these are the best by far. Worth the money, totally!
