EneloopPanasonic BK-3HCCA16FA pro AA High Capacity Ni-MH Pre-Charged Rechargeable Batteries, 16-Battery Pack

I use these in trail cameras that are out in the woods in the winter. They last longer than the standard Eneloops which themselves are pretty great. I started using Eneloops years ago bc they were the only rechargeable that would give good life in my early digital still cameras. There are other knockoffs now, but I have had zero failures on my eneloops and they seem to hold charge ability through the years remarkably well. These things are expensive when you're buying a bunch, but they just last. A note--I have some in a Moultrie Edge cellular trail cam (the particular camera can take 8 OR 16 AA's). I loaded it with 8 freshly charged batteries and was shocked to see it read only 15% charge. I put it out anyway, and 8 weeks later it reads 6%, when I would have expected it to be stone dead within a week. My GardePro cameras show a full charge when loaded with Eneloop Pro's so it may be an anomaly of the Moultrie.

I have had great luck with Eneloop batteries and still have some functional after 15 years.Best I have ever used.

As a photographer I use a lot of batteries. These hold plenty of power, operate well even in cold weather, save a ton of money compared to disposable batteries, and most importantly, don't go into the landfill when they're depleted. Instead they go back into the charger. Never counted how many charges I get per battery, but it's likely in the hundreds. And they don't even move the needle on my electric bill. Truly a "no-brainer."

No clue why but my son couldn’t have been more stoned to receive these for Xmas. Pretty much his entire list. 😁

Many rechargeable batteries are sold with highly questionable power ratings. These Eneloop Pro batteries, however, meet the spec extremely well. On the detailed packaging they claim 2550mAh typical, with 2450mAh minimum. I have a Maha MH-C9000 charger which provides a high performance set of battery tests, including a 40 hour charge/discharge/charge recycle test that accurately shows the true battery performance on a 0.2C discharge test. So far I've put 12 batteries through this test getting the following power ratings from each: 2560, 2572, 2563, 2556, 2589, 2580, 2541, 2550, 2582, 2564, 2549, 2581. Frankly the consistency of this range is extremely impressive which is important when you're using more than one battery in a device you want them to be close to each other in performance, and the fact that they average above 2550mAh is also extremely impressive.For use in a camera flash gun (my primary purpose) the most important aspect is the battery power when shorted, so by testing the current delivery of the battery simply by shorting it out with my multimeter gives a very accurate indicator of how the batteries will perform in my flash gun. My initial tests showed a range of 8.65 to 8.8A.As a final test, my Nikon SB800 flash guns specs a recycle time of 4 seconds when used with NiMH batteries, pleasantly these batteries yielded a time of 15.8 seconds for 5 full cycles, wow 3.16 seconds each cycle for a 100% full power flash cycle on this big flash gun, that's impressive!

So this is not a normal review because people here already love these or hate these batteries.for me the batteries are great, but they have a serious flaw that is easy to fix but if you don't know how to fix it, you will end up simply throwing them away and thinking they are crap.Here is the issue:if you let these batteries discharge for a very long time they simply wont charge when you put them in the charger.i had this issue at first and may have trashed a few, but one time I accidentally electrified one by powering the + with + and the - with - with 5-8 volts for a second.That is all you need, and your battery is fixed.good luck.

We have only had these batteries for a few weeks, but they have charged and worked very well.

works great for price
