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

I originally bought my first batch of these batteries in AA and AAA sizes in 2021. I had purchased expensive Energizer and slightly less expensive Rayovac NiMH AA batteries a couple years before and was not impressed by their short life. Not short in charge life but short in the number of times they could be recharged before they failed permanently. I called both companies and was told about over-charging, high-current applications, temperature considerations, just about everything but why they failed in everyday use around the house in low current devices like flashlights, remote controls and small digital devices. So, I gave up on the national brands and bought a 24 packs of Tenergy AA's and AAA's along with their associated Tenergy 16 position AA/AAA charger and I couldn't be happier. This purchase of 24 more of each size is not for replacement of the original order but supplement to as I needed more of each. I have replaced all of the batteries in my home with these batteries and they have performed exceptionally. They are long lasting, charge well, hold their charge in devices that have a lot of stand by use (like flashlights) and I have had no failures in the 3 years of use with many, many recharges. These are superior NiMH batteries and are significantly less expensive than the natiuonal brands availble at big box stores. I heartily recommend these Tenergy NiMH batteries.

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!

I tried the cheap route first and bought the PowerOwl 8-pack battery + charger combo. It was worth it because the charger is really great, 5 stars for that, but the batteries sucked because 3-4 batteries were dead out of the box or within 30 days. I actually have a review here somewhere on those. The company contacted me and sent me replacement batteries, which was cool, and because that was cool I bought another 8-pack, but they both went 50% dead within a month too. I had similar experiences with Amazon-branded batteries. So THEN I tried the Tenergies, which were a little more expensive, and I have to say, this is a case of you get what you pay for. These batteries work great, and thus far, 6 months later out of the 24-pack there are only three that are going dead, which compared to the others is great! This is with daily use in battery-powered small garden lanterns and electronic devices like handheld game controllers. In summary, I will continue to buy Tenergy brand batteries going forward!

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

Speedy delivery, great pricing, item as described.

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

buenisima calidad

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!
