Samsung, Panasonic, and LG are undoubtedly confirmed for producing the best and original product which could be bought at Amazon’s website and Aliexpress website and if not, then ensure you buy from those that have stores or outlets and not from hawkers.


Having a battery with a higher mini ampere-hour should not be a bad idea since it is not detrimental to your devices. Not all higher capacity batteries can be used for lower capacity devices. If you should have a higher mah, then ensure it is suitable for your device.

The answer is no because the AA battery just has a similar shape to the 18650 battery, but their capacity and performances differ. It is a clear fact that 18650 batteries have a higher capacity than AA batteries. So using AA instead of 18650 may damage your device if not carefully managed.
