The Battery Difference: A Solution to Reducing Soldier Load and Increasing Effectiveness on the Battlefield

‘Just the facts’

    Using L91 lithium batteries:

  • Extends operational life by 300 percent to 500 percent;
  • Saves mission weight by about 600 percent; and
  • Saves logistical costs by 300 percent to 500 percent.


  • Do not mix batteries of different types or brands. They will discharge unevenly and can ultimately rupture and fail.
  • Using the wrong battery type affects the accuracy of your battery indicators or alarms. Developers designed night-vision devices, thermal sights and target locators to use L91 lithium AA batteries. Alkaline batteries will not accurately indicate, or alarm, their state of charge, but lithium batteries will.
