quick how to on aluminum sulfate electrolyte for lead acid batteries.

Step 1: Purchase Ingredients.

you will need aluminium sulfate, a hydrometer, distilled water and a two buckets.

also you will need a face mask. long sleeves, safety goggles and water on hand.

this job could cause death or serious harm from explosions and acid spills.

you will also need a battery charger, applicator bulb and common sense.
<p>I have made several of these Alum batteries and use a inverter to plug in a lamp during power outages. Depending on how bad your battery is sulfated they work well, holds 11 volts for hours</p>
<p>well after going through this , hubby would need a 6x4 shed the other end of the block . As for my phone battery and laptop battery that wouldn't hold a charge I wrapped it in plastic and put it in the freezer for a day then fully recharged it been good as gold since freezer wipes the memory so it takes a full charge </p>
<p>Im looking into if there is any fact or logic in this considering there is not such thing as Li-ion batteries having ANY kind of memory whatsoever, there are different control factors at play here</p>
<p>How can you trust someone who doesn't even know how to rotate a pic...</p>
<p>hahah beat that turned the laptop </p>
<p>is aluminium sulfate epsom salt?</p>
<p>Epson is magnesium</p>
<p>According to what I have been reading, you dont need to add any sulphuric acid. Just use the alum and water.</p><p>http://blog.hasslberger.com/2007/01/how_to_convert_a_lead_acid_bat.html</p>
<p>very goog tips</p>
<p>In step 5 I see:<br>&quot;feel free to use any ratio. I have found 20% sulfuric acid to aluminium sulfate works the best.&quot;<br><br>1) there should be NO sulfuric acid; lead alum is an Alkiline battery, not an acid battery<br>2) &quot;any ratio&quot; often in chemistry, a very specific ratio is required. This may be the cause of your results. One source says 10% alum to distilled water, by weight; and NO sulfuric acid.</p>
try it and see how it goes. im no longer interested in this subject. I figured the sponge lead fatigue was the major cause of failure. nothing you can do to put the powder back on the plate so why bother?<br><br>its like trying to put rust back on your car and hope it turns to steel.<br><br>my experiments were riddled with holes but actually doing it debunked it sufficiently for me. if you think there is more to it I wish you the best.
Any idea what the chemical reactions are? As far as I know, a sulfuric acid and lead battery discharges when the negative electrode combines with the acid to make lead(II) sulfite (PbSO4) and gives off some electrons; the positive electrode is lead oxide (PbO2) when charged and takes some electrons with the acid to make lead(II) sulfate (PbSO4).<br>
I dont know. I put a lead and lead oxide plate in the solution and discharged them to see what it was.<br><br>The plates did not go white. I think it may be aluminum. <br><br>But as a layman I cant say for sure. Wish I knew...<br><br>Btw there is little or no charge when you add the solution. Also they self discharge in a matter of weeks.<br><br>This was my last experiment after trying to resurrect dead batteries. The whole battery rejuvenation idea is bunk imo.<br><br>Moving on to hho to see if there is anything to that.
