Can't pull air through manual battery
I'm looking for some help figuring out why my 3 mo. old manual battery won't pull any air.
It was working properly. I charged it until the green light came on (about 3 hours), put a pre-filled cart on it (Wow VG vanilla), and got no air flow whatsoever. I took the cart off and thoroughly cleaned the battery terminal. I still can't get any air flow.
Besides the thorough cleaning, I've tried shaking it, holding the LED end, as though trying to get the last bit of ketchup out of the bottle. I've tried tapping it terminal side down, not very hard, on the table.
Try as I might, I couldn't find a previous thread that really answered my problem.
Oh vaping gurus... have you any help? :)
