You DV is new if I remember correctly. Have you charged it after use or while using to get that up a lot. The DV normal battery life is really long. You are not getting its full use yet. Keep charging that sucker and see what happens of course use it a lot as well. Run a few chambers charge, run a few charge. After doing this a bunch of times see if the life gets any better if not you might have an issue. It seems like the new DV's need to condition the battery. I am glad I didn't have to do this. It worked great out of the box and I didn't know anything about off gassing or any of that nonsense when I got mine and I guess over time either it went away or I never had an issue or it does it and I have no idea lol.
