Battery Water (revisited)
Really. Haven't we beaten this to death? Steam distilled will be as good as
you can practically get. If you're really anal, get triple distilled deionized HPLC grade water from Fisher Scientific or similar. It'll probably cost $50 a gallon, but hey... it's really pure H2O! "Glenn Ashmore" wrote in message ... Steve, the steam distilled is as good as it gets unless you pay through the nose for laboratory grade USP water. I have been playing with this Hanna TDS meter that I am putting on my watermaker. It came with calibration samples of USP water and a 1000 ppm TDS sample. I calibrated zero ppm with the USP water and 1000 ppm with the other sample then started playing with different samples. The kitchen faucet read 190 ppm. A sample of grocery store distilled water was 15 ppm. Less than 8% of faucet water. Steve wrote: Thanks for all the tips on finding distilled water for my batteries. However, I still remain sceptical regarding the quality of the supermarket "distilled water". In one store I found it labeled as "steam distilled" water but no reference to the TDS (total desolved solids). In another store I found two brands of "distilled" water. One label stated that it came for "Portland water system, charcoal filtered, Reverse Osmoses or steam distilation." I many not have the wording exactly, but that "OR" worrys me. Else where on the label it states that it has less than 1ppm solids. The other brand only indicated that it came from a plant in New Hampshire and gave a 800 number. Surprisingly, I called it at 1700 Pac. time and got a real live and helpful person. He had to go check when I as what process was used to produce the "distilled water". Without any prompting, as to what answer I wanted to hear, he came back on the line and told me it was Steam Distilled. However, I neglected to ask if he know what the TDS was for this product. I got the impression that he was just an answering service for the distiller and had to call someone for all technical matters. I purchased a couple gallons of the product that provided the info on TDS (1ppm) but now I'm unsure of how high a TDS I should allow.. I have no idea where to have a sample tested of the other stuff.. Anyone have any idea of what would be exceptable for my $600+ battery bank?? Perhaps I should call Trojan?? BTW. I had several gallon jugs of nice clean rain water. Well, after sitting on the shelf for 2 years, this water developed green algae bloom.. I dumpted it out but later, I realized I could have filtered it through coffee filters. Steve s/v Good Intentions -- Glenn Ashmore I'm building a 45' cutter in strip/composite.
