Are ARB-L18 and ARB-L2 batteries interchangeable?
The ARB-L18 batteries are upgrades to the ARB-L2 batteries and generally work with most Fenix models that use 18650 batteries. However, the ARB-L18 series are sometimes unable to be used in older Fenix models and the ARB-L2 series are sometimes unable to be used in current Fenix models. For example, the ARB-L2 18650 battery will not work in the Fenix PD35 V2 flashlight. However, the ARB-L18 series will work in the PD35 V2.0. If you have a specific flashlight in mind and want to know if the ARB-L18 battery or ARB-L2 batter will work with it, please feel free to contact us.
