There was a very similar thread addressing this issue about a year ago, a 374 owner was asking why the battery was crapping out after 3-4 weeks and he was advised to unplug the bass when he's not using it. Well, I've had this 374 for about a month and a half and I've already had to change the battery twice. I'm always careful to unplug it when I'm not using it. How often do those of you with active basses need to change the battery? I was under the impression that you should only need to change it a few times a year, not once every 3 weeks. Do I actually need to remove the battery from its compartment when I'm not using the bass? By the way, for the record, this time I didn't get any warning whatsoever, the bass sounded fine the last time I used it a couple of days ago, then this morning it's barely making a very quiet farting sound. The battery must have completely gone dead while the bass was just sitting there unplugged for a couple of days.
