Subject: 12 volt battery rejuvination/restoration
Content-Type: text/plain; charset="us-ascii"; format=flowed
Has anyone on the list seen the youtube videos on rejuvenating a 12
volt battery and tried this. I am a bit skeptical of what could be a
backyard chemistry experiment that becomes a potential ticking time
bomb. The poster on youtube drains the exhausted 12 volt battery of
acid and flushes it out with a solution of water and baking soda. Okay,
makes sense so far. Then the battery is filled with a solution of alum
and water and set to charge. The poster later suggests that a bit of
salt may be added to prohibit the battery from freezing in extreme
temperatures. I would hate to rejuvenate a battery in this way if it
might pose any sort of hazard with electrical damage, seepage,
excessive offgassing or some other more disastrous consequence. I hope
this is not considered a Friday topic since a lot of our vans are
second or third vehicles and do not get enough battery life by
potentially sitting so much unless kept on a constant trickle charge.
Any chemists or electrical gurus on the list have any input on this.
Here is the URL for the video I watched with a healthy degree of
skepticism. http://www.youtube.com/watch?v=Supe1a3LW2U
