Not to add to your confusion, but...
Distilled water does not have any electrolytes, it's simply H2O, hydrogen and oxygen, nothing more. That's good because, as slimvulcanrider stated, there's nothing to deposit on the battery plates like tap water has.
Battery acid is sulfuric acid. You would normally only add this prior to initially charging the battery when you first bought it. After that, just add distilled water when the levels are low. The only other time to add sulfuric acid is if a particular cell has a very low specific gravity even after being filled with distilled water above the low line and then fully charged, and that means you would need to check the specific gravity of the fluid in all the cells. Most of the time, however, the reason a battery fails is not because of low acid levels, but because the battery has become sulfated or has filled with sediment and therefore has shorted out. Adding sulfuric acid won't help a shorted out battery.
By the way, every time you connect a charger to a non-maintenance free battery, the kind with the vent tube, the battery looses some fluid through the vent tube. So frequently charging your non-maintenance free battery, even with a battery tender, will make it even more important to check your battery fluid levels at least monthly. Otherwise you will find yourself stranded with a dead battery that you just charged.
It's much easier to simply replace the stock battery once it fails with a maintenance free glass mat battery. You won't have to worry about checking the specific gravity and this battery will hold a charge longer. There's practically no chance that this battery will spill acid all over the delicate electrical components near the battery case, and you will be less likely to be stranded somewhere because you didn't check your battery fluid levels every month.
