   It's a car battery. It's not a silicon based integrated circuit.   
   Water is water. To a certain degree it's all the same thing.   
      
   I don't know the answer for sure, but I would reason out that almost all   
   tap water will be just fine in a car battery although I don't doubt   
   chlorine (or chloramines?) that they put in them might affect the lead:acid   
   chemistry.   
      
   They add fluorine too I think, and there might be a decent amount of   
   calcium carbonates and metallic ions such as copper and phosphorous.   
      
   I'm guessing that the minute amount of such things (having owned a pool,   
   I'm aware they're in the PPM range, and PPB for phosphorous) in a car   
   battery designed to last five years, won't make one bit of difference.   
      
   An example of tap water total alkalinity is around 50 to 200 PPM and the   
   calcium hardness due to calcium salts would range a bit higher, maybe   
   double (depending, of course, on the amount of old shallow seas in your   
   area fifty to two hundred million years ago).   
      
   But distilled water is cheap and rain water is even cheaper, and, in fact,   
   so is tap water - so since they're all dirt cheap, may as well use the rain   
   water.   
      
   That's how I see it from a reasoned approach, where I'm very familiar with   
   the scare tactics pool stores try to pull on people when they find   
   something, anything, to say "oh that's going to damage your equipment."   
      
   Same technique those Indian "Microsoft support tech" try to pull on you   
   when _they_ call you and tell you to look in the Event Viewer and all those   
   errors indicate your computer needs their expert help with ransomware   
   addition.   
      
   Overall, does ANYONE have ANY real data that tap water actually degrades a   
   car batter enough for someone to actually measure the results in 5 years?
