DUAL FUEL CAPABLE FLASHLIGHTS-IMPORTANT NOTES This flashlight allows disposable batteries to be used in place of the included lithium ion rechargeable cell. This Dual Fuel capability is for backup purposes-lumen output run time and other performance metrics will vary with the use of disposable batteries.

ASP CR123A batteries recommended as Dual Fuel backup for lights using 18650 rechargeable cells. Major brand lithium AAA batteries recommended as backup for lights using 10900 rechargeable cells.
