How would you compare the performance of the Ni-MH 1.2V battery and the lithium 1.5V battery?Updated 5 hours ago
In most Fenix flashlights, runtime is comparable between the two despite the voltage difference, because Fenix lights are regulated to draw the current they need rather than depending directly on raw voltage - capacity (mAh) matters more than the small voltage gap between 1.2V NiMH and 1.5V lithium. Check your specific flashlight's manual to confirm both are supported.
