Can Fenix AA flashlights use Li/FeS2 batteries?Updated 13 days ago

It depends on the model. Many Fenix AA flashlights list 1.5V lithium (Li/FeS2) AA batteries as compatible, but compatibility varies by light. Please check the battery table in your light's user manual or on the product page of the AA flashlight you're interested in to see which batteries are compatible with the flashlight.
