What's the downside?
Seems if something that simple was a good idea, the battery manufacturers
would have already exploited the benefit??????

The downside for the manufacturer is decreased sales. I have seen  
perfectly good batteries come my way for almost free just because  
someone didn't follow directions.

A 4 to 1 mixture of distilled or rain water & epson salt to help keep  
your batteries in top condition.

4 parts of distilled or rain water
1 part epson salt

You can make a quick batch using a microwave and a glass measuring cup.

I like to make a half gallon at a time and keep it on hand at all times.

1. Bring the water to a slight boil.
2. Add epson salt and stir until it is all dissolved. Never add epson  
salt without first dissolving it. It will just sink to the bottom and clump.
3. Allow mixture to cool.
4. Add in each cell as needed. If possible, shake the battery to mix it  
up good.
5. Do not overfill your batteries. It will overflow and make a mess. a  
1/4 inch over the top of the plate is more than enough.

You can also try this recipe with batteries that no longer hold a good  
charge. Marine, Golf Cart, and Fork Lift batteries are best to use  
because the plates are much thicker. Car batteries plates for the most  
part are thin, and they disintegrate easily over time.

You can use car batteries if you do the following:

1. Completely drain the battery of all liquids.
2. Add baking soda to the old battery acid to neutralize it, and safe  
3. Rinse out the batteries a few times using rain water (free). Rinse  
until the water comes out clear. DO NOT USE A WATER HOSE. You can use  
compressed air and a plastic tube if you want to agitate the plates. The  
impurities in in normal drinking water will destroy your battery.
4. Make your 4 to 1 mixture, and allow it to cool.
5. Pour it into each cell.
6. Leave the fill caps loose.
7. Charge your battery at no more than 2 amps for about 3 days.
8. Take readings each day and write down the results.
9. After the 3 days have passed, do a load test. You are not going to  
get a full 100% of the rated CCA, but if you get 50-90 percent, then you  
are good to go.

Keep detailed records of each battery you do this to. Using a soldering  
iron or evgraving tool, give each battery a unique serial number. This  
will save you headaches in the future, and prevent you from wasting time  
on a battery you already reconditioned many times in the past.

Many preppers pay $-$ for old car batteries and have achieved  
excellent results with this method. There is no need to pay top dollar  
for batteries that will die eventually. You can repeat this process up  
to 3 to 4 times before a battery will finally die completely. Think  
about what you will save in the long run.

I prefer using smaller pallet jack batteries. Each 2 volt cell weighs  
about 50-75 lbs, but a $00 used set will last 30-40 years if you  
maintain it correctly.

 Yes and no. However, mostly no. See this wiki article:

<http://en.wikipedia.org/wiki/Lead_acid_battery>  for the full

 In particular this section:


  TBH, I'm surprised it was left to me, a mere lurker in this NG, to
point out the 'bleeding obvious' and provide those links.

You beat me to it.

I was struggling to simplify this to show why adding -more- sulphate  
won't help reduce lead sulphate on the plates, although it may  
temporarily increase the conductivity of the electrolyte and make the  
battery seem better.

I've gotten a few more years from a 'dead' U1 battery in a 'dead'  
riding mower I was given by forcing current through it with a higher  
than normal voltage, to break down the crystallized sulphate. You have  
to check and top up the water level while doing this.

I take better care of my own batteries and this desulphating process  
has less effect on them. I think they die from other causes, like the  
cheap construction of batteries from WalMort.
