These batteries are a must in the ATN Xsight 2 line of Night Vision Scopes. If your tired of 2 hours on standard AA batteries or 4 hours on AA lithum batteries, look no further. This is the most used batteries in many ATN Xsight Scopes. I am getting 8 hours run time on my scope with many of the features turned on an running. I cant function being task as a invasive species removal operator with out my scope running at least 6 hours on a set of batteries. These fit the bill. You will not be unhappy. Give them a try....
