Yes, absolutely right. The AVO voltage convertor VC1, for instance, always seems attractive in that it allows all the resistance ranges to run off the single 1.5V cell. But, it's "on" all the time. Even though it uses very little current when idle, the cell will eventually drain to nothing and that's when you can expect leakage to occur. The VC1, is great if the meter is in constant use. Not so great if only used occasionally.

Morale: if you've got a VC1 and haven't used your meter for a while, check it RIGHT NOW and get the cell out. In fact, even if you haven't got a VC1, do this anyway!
