18560 rechargeable batteries are the highest volume standard battery used in lighting products. They are a great alternative for products that utilize 2xCR123A disposable batteries. Not only are you being environmentally friendly by eliminating disposable batteries, 18650 rechargeable battery provides different levels of capacity for your exact need. For example, you can get 30% more capacity out of a ARB-L18-3500 compared to a ARB-L18-2600.

In addition, Fenix batteries are built with safety in mind. There are built in features to prevent short circuits, design multiple layers of protection and the new button-top design. The high capacity 18650 Li-ion rechargeable batteries each provide protection circuits in the anode to help prevent short circuits, over charge/discharge and over heating. Each battery also includes pressure relief vents which expel waste gas in the rare case of an internal short circuit preventing an explosion.
