TenergyPremium High Capacity NiMH Rechargeable Battery Combo, 12xAA and 12xAAA Rechargeable Batteries, 24 Pack

The batteries are a little bigger in diameter, so they won't fit in my X-box controller, but I have plenty of other rechargeable batteries that will, so I really don't care, they fit in everything else just fine. So far they seem like a great battery and I will update when I've had the chance to cycle them a few times as to their charge lifespan. I plan to buy more in the future.

These are awesome batteries with very good energy ratings for Ni-MH rechargeables - 1,000mA for the AAA's and 2,500mA for the AA's. Excellent amount of rechargeable batteries for the price.

RATING: 3.75 stars. Slightly above average, as compared to other brand rechargeables in a similar price range. Generally, these are a better buy than Eneloops, which can cost 3 to 5 x more (but don't last 3-5 x longer). Tenergy packaging & presentation could use lots of improvement.All 16 batteries (8 AA + 8 AAA) arrived uncharged and/or close to dead. This is a huge missed opportunity by the manufacturer to impress their customers. Other manufacturers have consistently sent their rechargeable batteries at least 50% charged, but Tenergy has been hit-or-miss.At any rate: prepare to spend a day or more charging all these up, unless you have a fancier charger than can handle all 16 batteries at once. We use the 4-slot AA/AAA Tenergy charger ( https://www.amazon.com/Tenergy-Battery-Charger-Portable-Batteries/dp/B07TGT9D98 ) which works fine but is a bit cheap; you have to supply your own power plug for the included USB cord.Presentation: POOR / Needs Improvement.Arrived uncharged or close to dead, in a plastic bag with NO useful information, NO safety info, NO charging instructions, etc. Nothing but a card with very tiny print, urging us to join some kind of Tenergy 'club' online (NO thanks). Promoting unnecessary online junk instead of giving useful or safety info about the actual product is a good way to NOT impress your customers.The claim that they hold 85% of their charge after ONE YEAR while sitting in storage... well, in real life, this has not been our experience. It's more like 2 to 3 months before a noticeable decrease -- not 12 months. Your experience may vary. A professional battery testing device may be handy.However, they function well in most devices around the home, and last long enough before needing a recharge. A few devices physically won't accept the Tenergy AAs well; they seem to be very slightly thicker than a normal alkaline battery, and the (+) post is s smidgen shorter. A few devices don't like the initial lower voltage (~ 1.2 volts), but this is not a super common issue.Would we buy these again? Yes; if they last 5 years or 50+ charges, they are definitely worth it. But for a few specific or finicky devices, we still stick with normal one-time use batteries (alkaline or lithium).

Have no problem with them they work pretty good

I'd buy more but they aren't cheap but they last a long time

We have bought Tenergy batteries before. Work very well. We still are using the ones we bought 2 years ago for gaming controllers. Still going strong. These are for remotes. I love that they last so well and are so reusable. Less waste!

He's batteries holder power for a very long time excellent product

One of the AAA batteries went bad after second charge
