I have an HCigar vt133.
When I press the trigger, the display lights up and shows the batteries as totally empty, and won't fire. I popped the batteries into a different vt133, and sure enough, both batteries full and working fine. I even tried another set of new batteries, checked to make sure they're fully charged, and same result. Display comes on, battery indicator reads 0%.
Any ideas what could be causing this?
