Good batteries
I love these batteries. I use them in my spypoijt cameras. They don't last quite as long as the high dollar energizer, but close enough since they are rechargeable. I just wish I could buy a bulk amount without having to buy another charger

Very long lasting battery. Haven't seen a AA like this before
Holds a lot of charge capacity, functions great. The design of the top of the batter is a bit narrow so some AA charges wouldn't work with it, but it comes with a convenient charger so was great for me. Now don't need to recharge my aa batteries so often thanks to the large capacityUPDATE:These batteries hold so much charge. This keeps candle lights on for two weeks straight. My bubble machine still hasn't finished it yet for over a month use by my children. All other aa batteries I had didn't hold close to how much these do!

Economy price with amazing performance
These batteries perform exactly as I had hoped. The time for them to fully recharge is minimal.

Tested pretty well.
My tests are complete. The performance of these batteries only looks bad when compared to the product details, not when compared to other batteries.Pros:They charge fast, in less than 3.5 hours. (I never timed these against the 2.5 hour claim, but I know it's less than 3.5)They deliver a constant voltage.Capacity is about the same as standard alkaline battery—but can be recharged.Cons:Not for use in devices that depend on low voltage to warn about low battery.They do not contain enough power to be labeled as 3600mWh.The tests: Constant Current capacity test (CC), Portable CD player and my contraption.CC, drain the battery to measure the capacity. My tester is calibrated to be reasonably accurate.400mA, cutoff at 0.8V.SinceHoly 3600mWh was able to deliver 2279mAh or 3400mWh and drained in 05:42:18.Similar 3600mWh was able to deliver 2229mAh or 3312mWh and drained in 05:34:33.NiMH 2800mAh was able to deliver 2515mAh or 3096mWh and drained in 06:17:27.Looking at the results compared to the NiMH, these didn't last as long, but delivered more voltage in the run time, resulting in more mWh.Portable CD Player, made around the year 2006.Full volume, Repeat full CD.SinceHoly 3600mWh played for 44:39:42.Similar 3600mWh played for 44:32:13.NiMH 2800mAh played for 43:53:40.Standard Alkaline played for 44:39:30.There you have it. On this low power draw device they all come out similar.My contraption, basically a motor geared to a counter.Run until the motor stops.SinceHoly 3600mWh got 10044 and ran for 75:30:35.Similar 3600mWh got 10071 and ran for 74:25:12.NiMH 2800mAh got 10376 and ran for 93:59:18.Standard Alkaline got 11257 and ran for 106:24:16.These are able to make more turns in less time because of the constant voltage. The Standard alkaline got the most points, but also it was running below 0.8 volts for like 3 days.I will not test the recharge cycle amount claims. I'm sure it's many cycles. I have some graphs to try and show the way that the voltage acts compared to NiMH and alkaline in the CC test. The alkaline I used for the graph is not a top brand.Conclusion:These are really good batteries and well worth the cost. I was never able to get close enough to 3600mWh out of them, but not for lack of trying. I'm taking one star off because it would not have been hard for them to label/advertise these as 3400mWh.Feel free to ask for more comparisons and such in the questions.

Powerful and long lasting
This batteries are a great product! Charge super quick, and last for a long time! The charging dock is super small and do not take any space! Definitely a must for electronics at home! Will save you lots of money!

Doorbell and Camera lithium
Very good item. Using with Blink doorbells and cameras. They take Lithium batteries and the regular 1.2v rechargeable battery doesn't work. Put these in doorbell and lasted over 90 days before needing recharge. Compare price to disposable lithium batteries and this is a BIG WINNER. 1.5v lithium rechargeable recommended. Seller Recommended.
