Introduction Can three 18500 lithium batteries replace three AA batteries? They are used in 8 W flashlights. THANKS. It's dangerous. This definitely won't work. This will burn out the flashlight circuit or immediately damage the battery.

Can three 18500 lithium batteries replace three AA batteries? They are used in 8 W flashlights. THAN

Dangerous, definitely not possible, it would immediately fry the flashlight circuit or cause battery problems. The reason is that the full charge voltage of the battery is very different: the voltage of each AA battery is 1.5 and that of 3 cells is 4.5V, while the voltage of a lithium battery reaches 4.2V and that of 3 cells is 12.6V. Secondly, although the voltage of a single lithium battery is similar to that of three AA batteries, the discharge current is different from that of AA batteries . A special protection circuit must be equipped, otherwise the main part of the lamp head will be burned. , or the battery will be discarded due to over-discharge. Finally, it could be a hardware error. The appearance of the 14500 lithium battery is the same as that of AA dry batteries, while the 18500 lithium battery is smaller.
