Two variants of Lithium batteries are ideal for flashlights: Lithium-Metal and Lithium-Ion. In this article, we'll state the difference between them to help you choose the battery right for you.
CR123A (Li-MnO2, non-rechargeable)
CR123A is currently the most popular model of lithium primary batteries, and one CR123A costs about $1.2. Once depleted, they must be replaced. Most tactical flashlights require two or even three CR123A batteries for operation. In this regard, CR123A seems to be a costly option, but why do people still use CR123A batteries?
CR123A batteries have a considerable wide range of operating temperatures, meaning they can withstand extremely cold or extremely hot environments. Moreover, they boast a lengthy shelf life, up to 10 years under proper storage conditions.
Can retain charge for up to 10 years
Wide operating temperature range (-40oC - 60oC)
Inappropriate for high output flashlights
18650 (lithium-ion, rechargeable)
18650 also happen to be the batteries used in Tesla's electric cars. Compared with CR123A, they are a little less tolerant to extreme environments.
Can support much higher currents
Poor shelf life
Slightly more complex (risk of overcharging/overdischarging)
Apart from the differences above, you'd better make your choice after understanding the flashlight manual and battery availability near you.
