Mayhem,

Any idea of how much amperage that was pulling on average?
And I'm assuming a 12 volt charger?

It sure looks like it did the trick!

By the way..... NICE PICTURES!

[Mayhem]

The charger is an old one that is capable of charging up to six 6V batteries at one time. It will also charge 12V batteries. I have never bothered to meter the output. I just recall seeing a plate that mentioned the six battery ability. Come to think about it, none of the knobs are marked. I usually just move them until I see a decent current draw on the meter.

Initial draw was a little over 6A but this reduced to about 4A after about an hour or so.

Nicely shown Mayhem

great shot of the crud

Your are actually Electrolytic Cleaning ,, and its the rapid production of Hydrogen gas at the surface of the Cathode that dose the cleaning .

The more amps you can get into the job the better ,, actually 6v to 12v with a current density of 10amps./ sq ft .

Just remember that's HYDROGEN gas is being produced . ( BOOM )

Baking soda you say? I thought it had to be washing soda like the Arm & Hammer stuff. Guess not.
Don't try it with one of the newer chargers that electronically control the charge rate, they don't output power until they sense the power in the battery to be charged. (I wonder if they won't charge a DEAD battery for that reason?)

Mayhem,

That is quite impressive, just to be sure the "work piece" is connected to the negative.
Is that correct?

Hi Steve ,,,,,,,,,, any Alkali or Alkaline salt will do the job .Sodium Bicarbonate and Sodium Carbonate are both Alkaline .Sodium Carbonate being more Alkaline than Sodium Bicarbonate .

Yep ,,,,,,, the newer electronic battery charger are a pain in the butt , the battery needs to have at least some voltage for the charger electronics to register that it is actually connected to a battery before it will charge , older chargers were fitted with an over discharge button so you could charge a dead flat battery .


Finished waffling now Rob

[stevec]

Rob, do you put treakle on your waffles?

[mikecwik]

a bit off topic but if you have a battery that the charger wont recognize you can hook a good battery to the dead one to get the charger to pick it up and it will start charging it. most likely at that point its already catastrophically sulfated or dead celled recycle material but it doesn't cost much to try.
