Using lead from batteries

Aside from the fact the acid neutraliztion/disposal poses a problem and a hazard,  can lead from  lead storage batteries be used.  Never seen it mentioned on the forum. Just wondering.

From MSDS sheet on auto battery composition:

INGREDIENTS (Chemical/Common Names): CAS No.: % by Wt: EC No.:
Lead, inorganic 7439-92-1 43–70 (average: 65) 231-100-4
Sulfuric acid 7664-93-9 20–44 (average: 25) 231-639-5
Antimony 7440-36-0 0-–4 (average: 1) 231-146-5
Arsenic 7440-38-2 <0.01 231-148-6
Polypropylene 9003-07-0 5–10 (average: 8) NA
NA: Not applicable; ND: Not determined

Average of lead content is around 65%, the thing is it doesn't say pure lead.
I always figured the material from batteries is like alloy from wheel weights, who knows what is in them.

Plus all the toxic crap that is formed inside a battery by the interactions of the sulfuric acid.

06 - from Cast Boolits ... (You need to Login or Register to view media files and links)

Salvaged battery lead should be avoided at all costs. Since the advent of the maintenance free battery the lead content has been reduced and elements such as strontium, calcium and others have been added. Most of these elements cast very poorly, ruin a pot of good alloy they are blended with and are extremely toxic. The quantity and quality of lead from batteries is not worth the risk or the effort.

From "Linstrum" on the Castboolits forum - Maintenance free/low maintenance batteries use calcium metal-doped lead to catalyze the hydrogen gas. The lead alloy used in batteries also contains a bit of antimony and arsenic to help harden and strengthen the lead. When hydrogen comes in contact with arsenic and antimony, the hydrogen reacts to form ammonia analogues called arsine and stibine, AsH3 and SbH3. In World War One the Germans experimented with these as war gases. As such they were highly effective since they are deadly in amounts too small to easily detect.

Do yourself and everyone else in the vicinity a favor and DO NOT use batteries. Severe lung damage and even death could result. Sell the batteries to a recycler and let the professionals deal with the risks.

Thanks,  that is good info to have.  I had no plans to tear into a battery,  simply because I've got no way to dispose of the acid.  And  from  having worked in a chem lab,  a little bit of acid can create a big ****ing mess.      Thanks KAF for the msds, great place to look,  never thought about that.

and westerner,  I ho ho ho ho hope the poison clears out so you can get to 4000 posts !!
