Otherwise they may have heard of a hydrometer and  dry charged
batteries which need electrolyte added to make them operational.

For your information a dry charge battery does not actually have a  charge 
added to it. It becomes charged when you add the Electrolyte which  creates the 
chemical action that produces the electricity. Charging a battery  removes the 
sulfuric acid from the plates and returns it to the water so that  you can 
have more chemical reaction to create the electricity.
 
Take a piece of copper and piece of lead and put them in a bottle of water  
you will get nothing, then replace the water with some juice from a  grapefruit 
and measure the amount of voltage that it  creates.

Here  is a part of the site that I have mentioned.

14.7. Pulse chargers,  desulfators, aspirins or additives will revive 
sulfated batteries.
Using  pulse chargers, desulfators or additives are very controversial 
subjects.  Despite claims of the manufacturers, most battery experts agree that 
there is no  conclusive proof that pulse chargers work any better than constant 
voltage  chargers to remove permanent sulfation. They also agree that there is 
no  evidence that additives or aspirins provide any long-term benefits. Short 
term  gains are achieved by increasing the acidity (Specific Gravity) of the 
battery,  which could increase the Amp Hour capacity, but increase the water 
consumption  and grid corrosion and decrease the overall service life of the  
battery.
