Waw I did not expect such an overwhelming reaction to my edta article, 127 messages. Glenn, you 'must' definately put it up on the web.
As most of you ask the same questions here are a few answers. 1. What is it ? Full name: tetraacetic acid disodium salt Molecular Weight: 372.24 Chemical Formula: C10H14O8N2Na2.2H2O Basically it is a salt. It is harmfull and irritating so use proper safety measures. It comes as a white powder that needs to be disolved in destilled water. PLEASE FOLLOW THE INSTRUCTIONS TO THE LETTER. 2. Where to get. I got mine from http://www.pureresearch.co.uk/ go to the bottom of there webpage. The first part goes on about GSM (mobile phones). Do a search on yahoo for 'edta+battery', I am shure you'll find one closer to you. I have no affiliation with pureresearch at all. 3. You need to follow the instructions : EDTA does not desolves in the battery accid so it needs to be disolved in distilled water first and it doesn't disolve wel in water to. So shake long. 4. After adding leave the battery a day or 4 for mixing before you start charging. THIS IS IMPORATANT. I found a few charge-disscharge cycles to be most effective. Good luck and let me know your results.
