I've been trying to make a decision on whether to purchase the Clarity for a while now. The sticking point for me has been this whole "angry bees"/high revving. Tonight, the salesman contacted me because the charge was low and he knew that I wanted to test it on a low charge. There were two bars. But I wasn't sure if this meant the battery was completely depleted or not. How can you tell? Is there somewhere on the dash display where it says the electric range is at zero? And if it's at 2 bars, is it likely the battery was depleted?
