<VV> batteries shipped dry

[Eric S. Eberhard]

I have done this twice -- I just go to Napa and buy a box (with a 
plastic bag in it) of acid.  I follow the instructions which are to 
pour it in and wait.  No charge, put it in the car and go.

The first one I did was an NOS battery.  The instructions said it had 
a shelf life until 1966.  I used it in 2001.  It was still perfect in 2009.

The second was a fork lift battery from California Corvairs.  It is 
the originals size and looks stock, less the markings.  And cost a 
lot less than a full repro.

I am not convinced that anything more than following the instructions 
on the package from NAPA are required :-)
