Default [Q] Erratic battery life with MOAR 8.0

Running MOAR 8.0, I am getting days of great battery life, then occasionally the battery dies within a few hours, dropping quickly. The strange thing is that the battery gets warm to the touch when fast drain occurs, but is cool under normal circumstances. I have three different batteries, and thought it might be a battery issue, but the same thing happens on any one of the three batteries. Anyone else experience this sudden fast drain?
