Tenergy Premium PRO Rechargeable AA Batteries, High Capacity 2800mAh NiMH AA Battery, 8 Pack Rechargeable Batteries

I’ve been using these for over a month now, primarily in a mix of high‑drain devices like wireless gaming controllers and mid‑drain gadgets such as LED flashlights and remote controls. So far, they’ve consistently performed well and entirely replaced the need for disposable batteries around my house.Right out of the box, the batteries charge quickly and hold a strong capacity—often staying charged for weeks even in devices that I don't use daily. When used in my Xbox controller, I can go several long gaming sessions before seeing any noticeable drop in performance. That’s a relief, especially compared to budget rechargeables I’ve tried before that tend to lose charge fast between uses.Another thing I appreciated is the labeling and casing. The shrink-wrap is neat and doesn’t peel, and it’s easy to tell the charge orientation without touching the terminals—very helpful when I’m changing batteries in low-light situations. The batteries feel well-built—not loose or rattle-prone in the charger or when placed in the device.Over the weeks of use, I’ve also noticed they maintain power very well, even if a device sits idle for several days. The cells seem to have solid self-discharge resistance; I haven’t needed to top them up nearly as often as generic rechargeables. When I do charge them, they take a full charge in a fairly standard time frame—not painfully slow.Overall, these are easily among the best rechargeable AAs I’ve used in daily tech and hobby use. They save money, reduce waste, and keep your devices powered reliably—especially in gaming controllers, flashlights, and the like. I’ll definitely keep buying them.

I got these to replace used up batteries in solar lights and objects in our garden. They're nice and bright, once installed, and I've had them in use for a while with no sign of weakening. Well worth the price, these have the potential to give new life to anything that uses rechargeable batteries. I have these same batteries in solar lights that have been in use for months with no loss of the ability to hold charges with little or no bleed off. Very reliable

I use these batteries in my hand held scanner, and have had very good luck with them. I use the Tenergy Chargers, and they outlast the corresponding Energizer batteries buy well over an hour. They do loose some charge in longer term storage. I have been pleased with these batteries, and purchased more.

The 2800 mah capacity is false advertising. I have tested mine, and they all come in at either 2400 to 2500mah. Still a good battery, just a false claim by the company.

Long lasting batteries

When you live the life of a full-time rver find yourself needing more. That's why I turn to these batteries to power all the little things repeatedly. Longevity of these items is average I would say and work well in low temperatures. They were a good value for the money as I don't have to waste $18 on a pack of 30. Being rechargeable is what truly saves the Day no I purchased both styles so I don't know if this is triple a or double a. They both get the job done. Coming nice little packages to keep them sorted and protected and have a decent build quality. Remember being a full-time rver rechargeable batteries is a must guarding emergency preparation. Recommended have battery charger on hand.

These black Tenergy batteries are a major disappointment. They do not hold a charge well. I use them mostly for wall clocks and computer keyboard/trackpad devices. They need to be replaced after 1 or 2 days when used in the keyboard/trackpad --totally unacceptable. In addition, they seem slightly too large to fit some devices, such as my beard clippers.The older blue-label Tenergy batteries, by contrast, held a charge well and fit everything I put them in. I'd order those again, but never these so-called "premium" batteries. They are a total waste of money in my experience.

excelente producto.
