How to open the LuxProLP1100V2 flashlight to replace batteries. The tail cap is not unscrewing. The head unscrews donot want to force silver disk out.

The Luxpro LP1100V2 is easy to replace the batteries. You should be able to unscrew the tailcap and replace the 2 D cell batteries. The tail cap should unscrew counter clockwise to loosen. You should not unscrew the head because it will not give you access to the battery chamber. Thank you!
