Is there a replacement for distilled water , last week it was easy to come by next week maybe not so much .
Could you use filtered rain water ?
Could you use filtered rain water ?
Maybe make a distiller ?

Filtered rain water ought to work pretty well. That's what D Angelini uses I think. I have some extra but nobody here close.First Bank:16 180 watt Grape Solar with FM80 controller and 3648 Inverter....Fullriver 8D AGM solar batteries.

Lake Superior water. Has worked well for me since 1994.Island cottage solar system with appriximately 2500 watts of panels, 1kw facing southeast 1.3kw facing southwest 170watt ancient Arco's facing due south. All panels in parallel for a 24 volt system. Trace DR1524 MSW inverter which has performed flawlessly since 1994. Outback Flexmax 80 MPPT charge controller four 467A-h AGM batteries. Insignia 11.5 cubic foot electric fridge 1/4hp GSW piston pump. My 31st year.

O ok cool , that is a good thing to know .I had a nightmare last night that I was using well water and all the stuff that build up in my coffee pot was bubbling out the top of my battery bank , the stock market crash / virus thinking is putting me on edge .Out back flex power one with out back 3648 inverter fm80 charge controler flex net mate 16 gc215 battery’s 4425 Watts solar .

That distiller was what I was thinking about or something like the still in the swamp on the mash tv series . Cool

de-ionized water works if its done right.

The water from a dehumidifier is de-mineralized. Of course, it's a little refrigerator mechanism, so a power hog. My water source is a 1 gallon Sears distiller run as a dump load (like today). My new Surrette S550's use very little water, most of it's being used in a humidifier to moisten up the house air (wood heat).

it is unusual for natural water in N America to be acidic. Water usually has an alkaline pH due to proximity to salts of calcium, magnesium and sodium absorbed from rocks and gravel - for starters.
I had a client with acidic well water that contained easily measurable phosphates. This confounded a large group of leading saltwater reef keepers. Some of us decided a probably cause was proximity to a septic system. The client moved.
Some areas have acid rain due to industrial pollution or a high concentration of motorized traffic. I'd much rather use acidic battery top off water than alkaline. Neutral pH is what we seek - 7.0 with no dissolved solids or organic compounds.First Bank:16 180 watt Grape Solar with FM80 controller and 3648 Inverter....Fullriver 8D AGM solar batteries.

The collection source for rainwater probably needs to be metal. Any petroleum based roofing would be suspect. At the minimum any collection source should be professionally measured for contaminants. At least once and probably every 5 years.
A Britta or similar filter is good insurance but most all rainwater out of a tank that has set for a couple days or more is going to be good. Connection piping needs to be non metal.
I have never noticed anything in negative from using rain in batteries for my home and clients in over 30 years. We still run a 48V FLA as insurance to our lithium based electronic batteries. They both are nice to have."we go where power lines don't" Sierra Nevada mountain area

Deionizer water filters are out there, some/many/all for battery filling can include a go/no go light (probably measures the water resistivity--Filter exhausted, start getting more minerals in the water):
https://www.sbsbattery.com/products-services/by-product/battery-maintenance-safety-accessories/water-deionizer.html
https://solusgrp.com/water-deionizing-system.html
Not finding much in the way of prices--The few out there appear to be all over the place. The one above is probably in the $400 +/- $20 range... Although have seen prices from $300-$1,100 for similar units with a quick browsing of the web.
Supposed to be good for 600 Gallons, but depends on the "feed water". 100 ppm TDS is 600 Gallons. If your water has higher TDS, then life goes down (can be 250 gallons or less with--Probably something like 300 TDS and 200 gallon capacity ratio).
A bit more technical:
https://www.total-water.com/blog/quality-vs-quantity-use-mixed-bed-deionizer/
Does not sound like a cheap solution--And upstream filters prior to the deionizer bed filter is, most likely, needed.

Some areas like West Texas may have TDS of 1000. We called it liquid rock. TDS varies, I have a vague memory of ~700 from a previous well. Or was that Denver water? Old memories for sure.
De-ionization is in for a short life when the source water has a lot of minerals.
You can test for mineralization by simply filling a glass with water and letting it evaporate. Any white chalky substance remaining at the bottom of a dry glass is minerals that you do not want in your batteries. Mostly calcium, calcium is highly abundant in rocks. The earth is a big rock with a lot of water.

Batteries last longer when they are properly charged. Maintenance is important but undercharging is almost always the problem."we go where power lines don't" Sierra Nevada mountain area

Of course.
706jim got 19 years out of basic deep cycle batteries. Something unique was going on.
I replaced a couple 9 year old 8D's when they showed 12.2 morning volts while the rest showed 12.5. The change was almost immeasurable. Tester said they were still "good" and showed 53% healthy. I console myself by telling myself they would have gone bad soon.
The way I see it - we never quit learning about batteries. Especially will all the newer technologies.
Here is a great test of different 18650 lithium batteries. The Chinese manufacturers claim 3 times the energy while delivering less than half the energy of the others. Or - about 12% of their stated claim. China's manufacturing reputation is sketchy though very good products can, of course, be made there. The Japanese and Korean cells delivered on their promises within 2%. The Chinese missed by 88%!

Hi Folks!Distilled water, unlike demineralized water, is purer, especially at a microbiological level (and is more expensive).For batteries, demineralized water should be fine, which, first treated by reverse osmosis and then further filtered through resins, should guarantee a sufficient degree of purity (from minerals).

Why use water that has maybe 99% of mineral removed when distilled water costs the same? At least it does in this area.First Bank:16 180 watt Grape Solar with FM80 controller and 3648 Inverter....Fullriver 8D AGM solar batteries.

softdown said:99% of mineral removedI'm agree with you, buying distilled water is the best thing to do!But I think the thread goal is a practical solution instead of a fast commercial transaction...So, what about using Water from your Air Conditioner ? Is it even worse?
