The Simple Method
As was mentioned, take either Vodka or 100 pure grain alcohol, place 2-3 drops in a condom, place battery connector in the condom and allow to soak for an hour. Remove from condom, with a whipping motion shake any excess fluid from the battery connector. Stand battery on connector end upside down on a piece of paper for 24 hours to drain and dry. Prior to use blow out battery with compressed air or orally a few time before attempting to use.
The Hardcore method:
In order to take apart any Auto Battery it's best to use a vice with rubber covered jaws, if you do not have the covers use a couple of pieces of cardboard. This will protect the housing from getting scratched and bent.
Once the battery is secured, take a garbage carto and screw onto the battery. The battery connector is a pressed fitting so take your vice grips and clamp onto the cartomizer.
Remember: Only tighten the vice enough to keep the battery from moving while turning the cartomizer.
It's the old righty tighty, lefty loosy, you will want to go clockwise in a tightening direction until the battery connector pressed fitting (pops) gives way and you will able to remove the contents.
This is where it gets a little tricky, there are 2 leads (pretty fragile) that are connected to a post on the opposite of the battery connector hole (generally where it shorts).
Try and left the actual battery by slowly raising the battery connector enough to access the white and black leads with some tweezers, lifting up on the battery. If the battery does not easily slide out, take a long sewing needle, pop the bling cover off by inserting the needle between the crome bezel and housing.
You should see a thin white plastic grommet around the circuit chip, take the sewing needle and run it around the several times, each pass with a little more pressure, then try and lift the battery out again, repeat until the battery slides out.
Once the battery is out carefully inspect the top of the battery and the lead connections to the battery connector post, clean if needed, reassemble. If done correctly everything should go right back in....you may need to take a ratchet head and lightly tap the battery connector back into the housing.
No guarantees.....hence the word "sacrifice". So
