AA Rechargeable Batteries with Charger, 3500mWh High-Capacity Rechargeable AA Battery,Constant 1.5V Rechargeable AA Lithium Batteries,1600Cycle,Max 3A Current[4AA+1Charger]

So far so good.

These charge quickly and can power a Game Gear for more than 8 hours, which is longer than most alkaline batteries. They are not for every application, however. In particular, I would not recommend them for AM radios. The voltage regulator inside the batteries generates a small amount of radio interference in the AM band - enough to affect the radio they are installed in, but not enough to affect other nearby radios. They are also not the best choice for devices that draw a very high amount of power or get hot, such as high-power flashlights. I have already had two go bad from being used in a 2000 lumen LED flashlight. That flashlight draws a lot of power and produces a lot of heat, so I'm not going to fault these batteries for that or take off a star. Overall, these are a great choice for most applications, but for radios and high-power applications, Ni-MH, Ni-Cd, or Ni-Zn batteries are a better choice.

I am very satisfied with the purchase of this kit. The batteries last and the charger appears to be of superior quality.

These batteries work really well and have excellent capacity. They charge quickly and after many cycles are performing wonderfully. It’s important to know that the charger they come with can only charge these specific type of cells. Further you cannot charge these cells in a standard NIMH AA charger.When looking over the available types of lithium ion AA batteries that use an internal voltage converter like these two, I very much prefer the type that charge from USB directly so that you can still recharge the cells if you can’t find the charger they came with.If you are confident you won’t lose the included charger, then these are perfect.

Arrived quickly as needed
