I just put the ruler in...make sure the clamp is not submerged.
The brine 1 X teaspoon washing soda per 600 mls water... mix well.
My battery charger is 8 amp... when it was in the brine it showed on the amp meter as 1  3/4 amps...I will see if I can get a bit of stainless steel to suit the job. I did not do this inside..as there is a slight gas given off... Very easy to do.. but like anything, tried for the first time I showed a little caution.....keep rug rats and pets away.

Derek, going off topic, but given that your moving and I'm moving. 

I don't know what you're doing about appliances, but it costs lots of $ to move them.  & by comparison the energy efficiency of the new ones will save me lots of $.  I'm not sure I'm even going to move my old vacuum cleaner.   

Several have told me that a self cleaning oven loosens everything from cast iron.  & all you do after you have run the cycle is to have the vacuum cleaner beside you when you open up the cooled oven.  Of course, that will be my choice in stoves.  With the cast iron I have it wins hands down. 

& even if you have appliances where you're moving, I think it would pay to check how much electricity they use vs. the newer ones.

Yes, so I understand, the cycle goes up to 800' F.

Compare with other stuff for energy.

Remember, these are energy efficient applainces.  There is a huge difference.
