don't depend upon rain water being that clean.
The idea of running it through a filter to remove the particulates is a clue to the fact that rain collects quite a bit of stuff on its journey through the atmosphere.
It would be best to use a known entity like distilled water rather than gamble on rain water. If need be, set up a solar still - not that hard and not that expensive.
In researching for another post/question, ran across this detailed chart of what PPM levels are problems for various contaminants (page 11 in the English guide) from the Trojan Literature Page:Trojan Battery User's Guide (English)Trojan Battery User's Guide (Spanish)

re: "what was or was not put in distilled water decades ago" -- oh, gheesh! sorry to have caused such offense
Distilled water, by definition, has nothing put into it.
Rainwater is another matter, from the nucleus of dust that precipitates the drop to whatever it encountered on its way down.
But it is indeed true that batteries will work with minor levels of pollutants in their electrolyte solution. Some folks do quite well with their tap water in some places, I hear.
What you can get away with is one thing. What you suggest for others is another.

re: "that a bottle labeled distilled water may not be distilled" - consumer fraud is its own issue. Using it to rationalize a viewpoint in this context is a logical fallacy with its attendant problems.
re: "it's unfortunate that there seem to be a few hotheads on this form with a my-way-or-the-highway attitude" -- This is due, in part, to the nature of the medium. It has been a topic of study for a long long time (going back to usenet days, even).
The thing for all of us to do is to realize the difficulties and do what we can to avoid making them worse. That means being aware of our own feelings, that our perceptions of what we read may not be completely accurate, and trying to adhere to established guidelines for etiquette (see, for instance, RFC 1855) - and it means exercising tolerance and patience regardless of the pain ;-)

If I was in Haiti and I have been, (wall to wall blue Caribbean paradise) I would find a decent way to collect rainwater and that is what I would do. I would tell the OP there are alot more important issues with making a battery last decades than
using clean rainwater for maintenance.

Sounds like being a bit paranoid about water purity (from any source) may be a good idea if you have an expensive set of batteries.
Placed "TDS (total dissolved solids) Meter" into Google and came up with $25-$125+++ TDS meters.
Another tool. Yippee!
A three-alarm fire that damaged a San Carlos warehouse containing memorabilia belonging to rocker Neil Young started in a vintage car that he had converted into a hybrid vehicle, authorities said today.
An investigation determined that the fire started in a 1959 Lincoln Continental and spread to the warehouse. Young had outfitted the car with electric batteries and a biodiesel-powered generator as part of his company called LincVolt.
"We are still investigating the exact cause, although it appears to be an operator error that occurred in an untested part of the charging system," Young said. "We do know that the car has been operating perfectly for almost 2,000 miles and the system in question would not be in use while driving the car. We are investigating the components involved with plug-in charging."

.......... I have a related question: some FLA batteries are shipped dry and you pour in the acid when you get them. Ive allways used 100% acid, is this correct or should I be diluting it?
The drinking of distilled water has been both advocated and discouraged for health reasons. The lack of naturally-occurring minerals in distilled water has raised some concerns. The Journal of General Internal Medicine published a study on the mineral contents of different waters available in the US. The study concluded
Drinking water sources available to North Americans may contain high levels of Ca2+, Mg2+, and Na+ and may provide clinically important portions of the recommended dietary intake of these minerals. Physicians should encourage patients to check the mineral content of their drinking water, whether tap or bottled, and choose water most appropriate for their needs.
It is often observed that consumption of "hard" water, or water that has some minerals, is associated with beneficial cardiovascular effects. As noted in the American Journal of Epidemiology, consumption of hard drinking water is negatively correlated with atherosclerotic heart disease. Since distilled water is free of minerals, it will not have these potential benefits.
While a growing number of people prefer fluoride-free water for health reasons, others still suggest that—because distilled water lacks fluoride ions that are added by many governments (e.g. municipalities in the United States) at water treatment plants using fluoridation for its inhibition of cavity formation—the drinking of distilled water may increase the risk of tooth decay due to a lack of this element. Of course fluoride can still be applied to the teeth alone with toothpaste and fluoride therapy.
