Can I use the Fenix ARE-C1+ to charge an 18650 Li-Mn battery?
We would highly advice against charging Li-Mn batteries in the Fenix ARE-C1+. The ARE-C1+ User Manual states that the charger is only intended for rechargeable Li-ion batteries, Ni-MH batteries, and Ni-Cd batteries. Other types of batteries may cause battery breach, leakage, or explosion. Learn more about different batteries for flashlights.
