Which of AA batteries I should buy? Which of the AA batteries are the best ones?
Make an informed and conscious choice based on the results of different performance tests AA batteries from different researchers are represented below.
In many cases, the tests are performed at different loadings (1000, 500, 200, 100 mA, and so on). Which of these numbers should be considered?
Usually, the test results for the minimum current values of 100-200 mA (0.1-0.2 A) should be considered - these and smaller values of the current are typical for the vast majority of devices that use AA batteries.
Is it always rechargeable NiMh batteries are preferable compared to non-rechargeable alkaline batteries?

Is it always rechargeable NiMh batteries are preferable compared to non-rechargeable alkaline batteries?
Not always. For many types of devices (remote controllers, toys and so on) power consumption is so low that the battery lifetime is roughly equivalent to the device lifetime. So, there is no need to replace the battery during the lifetime and no need to use NiMh rechargeable battery.
