Auto Battery Issues

[Scottbee]

There IS a rubber diaphragm in there. As a matter of fact, if the battery is assembled correctly, it is sealed and juice can't actually make it into the battery internals.

The rubber diaphragm has a small magnet embedded in it that is in proximity to a thing called a "Hall Effect device", which is a switch that can sense the magnet.

If the diaphragm gets filled up with liquid or gunk, it can deform and the battery either won't come on, or it won't turn off. Ya need to get the gunk out.

Ok, so mine apparently got misaligned (it was a brand new replacement that I dropped 2 days after getting it), and I was able to put it back in place with the paper clip...

Correct me if I'm wrong, but the Hall Effect Device simply takes a mechanical signal(air flow in this case) and converts it to a digital signal, a square wave(on-or-off in this case). Is this correct?

Well I did what everyone said.. I plug it in it flashes blue a couple of times and wont charge. I can tap a guitar string down the center hole and get the blue light to come on and thats about it.

Its ruined...mine was acting the same way after I stuck something down to center hole to try to fix it from sticking on. Also I do not believe the hole is completely sealed. I have taken one apart and it wasn't.

Close....

The Hall Effect Device is a switch, that turns on and off based on the proximity of a magnet. In this case the magnet is mounted on the diaphragm... so when you suck on the battery, the diaphragm moves, and the position of the magnet relative to the Hall Effect Device changes.

In this case it's not actually air flow... it's air pressure (vacuum).

By design the diaphragm is capture by the plastic carrier and that should create a complete seal against the aluminum cartomizer receiver. At least on the one that I took apart (not to say that the design never changes). If you suck on the threaded end (lightly) of the battery and you get airflow, then your diaphragm isn't sealed. If you don't get any airflow, but the LED still comes on, then yours is sealed.

There is no good design reason NOT to seal them. I doubt they would have vented them on purpose.

Ok..I see what you mean....I was getting airflow through the battery that went bad...but get none from the new one. So its sealed but I still would not recommend sticking anything in the hole including liquid.
