# Explain why it's good for the game
A Smartgunner will ask a Cargo Tech for a DV9 and they will be unable to
search for one causing confusion. The battery itself is called a DV9
which is what the SG asks for and this edit fixes the vendor not listing
it as such.
# Testing Photographs and Procedure
Minor text change. I verified it in-game and it's working correctly.
