Tenergy Premium Rechargeable AA Batteries, High Capacity 2500mAh NiMH AA Battery, AA Cell Battery, 12-Pack

To be honest they do the job haven’t had any problems been using them for a while

Excellent product which I have used before and continue to buy due to it's record of satisfactory service. I have no hesitation in recommending these batteries both due to their performance and their durability.

I Have over 100 NiMH rechargeable batteries. More than half are Tenergy Premium. The others that have stood the test of time are Panasonic Eneloops. The couple dozen assorted other brands lasted at best a year. I am taken aback by the negative reviews that some people have left. It is sometimes hard to choose the right battery for the application. Some applications need wasteful throw away batteries which irks me. When it comes to camera flashes these are an excellent choice. I have three main flashes and and external and one external power pack. So I pretty much have 24 batteries in flash devices at any given time. I can't tell you why, but flash performance is the best with NiMH batteries. I have had alkaline batteries kill flashes. I don't know precisely why but that's how it is. My other use for AA's is in battery powered motion activated lights which are handy to have in poorly lit areas, I think I have 5 that take C sized batteries, for which I use AA sized NiMH batteries with a jacket around them, to make them physically the same size as C-batteries. Lastly, I have a 48 LED ring light that operates on only 2 AA batteries, and it does great with Tenergys. Maybe not 100% relevant, but I am very impressed with the Tenergy AAA's as well. I Have 3 Brother hand held label makers. They drove my first Tenergy purchase. They each take 6 AAA batteries. How long will a label maker run on AAA rechargeables? I find this amazing: I used up my first two tape cartridges and never had to recharge the batteries! They other two were for other family members, but they are happy with them too. Maybe I am making too big a deal about my good experiences with Tenergy, but when I see ten one star ratings I feel almost offended. And I have nothing to do with the company. These are damn good batteries. And I think the amount of batteries I use qualifies me to say it. If you really don't know how to charge use and store your batteries that doesn't make the batteries bad! I don't mean to be insulting but there should be no three star ratings much less a one star rating. And clearly, if you don't have specific experience with specific better batteries then I can't take those reviews seriously. If you get a damaged product, then get it replaced. If you bought the wrong type of battery for your use, that is hardly Tenergy's fault. One slight criticism: I would only say one thing I believe all rechargeable battery makers should, but seldom do, is to provide re-usable plastic boxes to store the batteries In. LOL- Do you really want 24 loose rechargeable batteries? I order clear plastic boxes, at the same time I order my batteries. Now that I think of it, Tenergy did include the boxes on some purchases because they have the Tenergy brand on them. Hey! Wassup? Start including the plastic cases again!

The batteries seem well built, I have only run them for a few cycles, but my initial feeling is they are quite good. The capacity of the cells is increasing gradually, which is expected. Overall, if these show good long term performance I will buy another pack as the value is very good. EDIT: After some time these batteries have shown very poor performance! You charge them, then a few days later, they go flat despite not being connected to anything. almost half the cells that cam in this bundle were defective and have progressively gotten worse with time and charge cycles. I would not recommend these at all. Spend money buying quality batteries, this was a wasted attempt!

Charged up to capacity and seem to last well. Would buy more.
