Yes, it is a general problem with active basses, @KenS - you have to unplug your bass every time you stop playing in order not to drain the battery (no matter whether you set the bass to passive or not). I didn’t do that when I first got my active bass and thought something was wrong with it as the battery died within a very short period. Now, I almost reflexively unplug when I put the bass down and thus the battery lasts for weeks! (Still, I always carry a fresh battery with me, as my bass is ONLY active - without the battery it is just 10 pounds of dead weight - beautiful, but useless).
