Re: battery and Epsom Salt
We tried EDTA and Epsom Salts in college and got a little more life out of what would have been a dead player. Not worth the hassle if you ask me. Here's some info from Wikipedia:
Many vendors sell chemical additives (solid compounds as well as liquid solutions) that supposedly reduce sulphate build up and improve battery condition when added to the electrolyte of a vented lead-acid battery. Such treatments are rarely, if ever, effective.
Two compounds used for such purposes are Epsom salts
. Epsom salts reduce the internal resistance in a weak or damaged battery and may allow a small amount of extended life. EDTA can be used to dissolve the sulphate
deposits of heavily discharged plates. However, the dissolved material is then no longer available to participate in the normal charge/discharge cycle, so a battery temporarily revived with EDTA should not be expected to have normal life expectancy. Residual EDTA in the lead-acid cell forms organic acids which will accelerate corrosion of the lead plates and internal connectors.
