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

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. Read more

These are in my opinion the best rechargeable batteries Read more

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.

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.

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 Read more

Very consistent and long-lasting as always. Other cheaper brands just don't hold up over time, and either fail to charge outright or discharge too quickly. These rarely fail, and hold their charge on the shelf a long time. Read more

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. Read more
