These are at best 2000 mAh batteries - poor quality.

I have done some basic capacity testing on these Tenergy AA NiMH batteries and my results do not match the stated capacity of 2500. I have found that capacity varies widely from cell to cell. Humidity, load 500 mA. They have been ridden at least twice, but the improvements have been marginal. Perhaps Tenergy uses a much lower load to get the rated capacity, but even that doesn't explain the large cell-to-cell capacity variation. I usually avoid Tenergy because I've never had good results with…

Pros
  • FOR EVERYDAY USE - Our ideal high capacity AA replacement battery is ideal for high/low drain electronic devices. Use it in all your home appliances like LED lights, flashlights, solar lights, night lights, calculators, remotes, controllers, cordless phones, RC toys, headlights, garden lights, headsets, alarm clocks and more.

Not nearly comparable to Eneloop

Don't let anyone tell you they're comparable to Eneloop. After purchasing this kit, I ran two simple tests. I removed the 3 year old Eneloops from the outdoor solar lights and replaced them with Tenergy. All enelupes glow throughout the night. Tenergy is barely visible at 10:00 p.m. because only the poles are exposed to direct sunlight throughout the day. The rest are long dead. As soon as 11 p.m., all Tenergy give up and Eneloop laughs. Likewise, I took a snowman for the house that chews…

Pros
  • Save money, be environmentally friendly - as one of the most economical batteries, Tenergy AA batteries are rechargeable up to 1000 times, 1 to 10 charges are worth it. You also reduce your carbon footprint by limiting the waste generated by single-use batteries. Switch. Save on computer. Reuse. Recharge your batteries with Tenergy.
Cons
  • boring packaging

Not quite 2600 mAh - Test Results

There are two things you need to know about rechargeable batteries: how much energy they store (capacity) and how quickly they lose energy just by sitting on the shelf (self-discharge). As noted by other buyers, the stated capacity of the Tenergy 2600 batteries is grossly exaggerated. I bought four dozen of these and tested them in groups of four with my Powerex MH-C900 analyzer/charger. After running in and 4 charging cycles of the batteries, none of them reached a capacity of even 2000 mAh…

Pros
  • No Memory Effect - With no memory effect in our AA NiMH batteries, you can charge your batteries anytime. Even when they are almost or partially used, you don't have to worry about long-term memory effects and you get the full capacity with every use.
Cons
  • Ugly packaging
