Batteries and Water Quality

What do the battery makers think about water quality?  They are pretty particular:

What difference does it make? This is what Trogan thinks:

How does yours stack up?

 And so now you know. I use either kitchen RO or dehumidifier water.

  1. I've had good success at making "battery water" with my water-maker as follows:

    * I make regular water into a container, usually about 3 gallons.

    * I then use that water as the feed-water to the RO unit and set my valves up so the the new product water feeds back into the same container. As soon as I start making water from the first pass I reduce the feed pressure to around 200 PSI.

    * I let the system make FW from FW for 30 minutes or so.

    * With three gallons of 1st pass RO water to start with I get about a gallon of FW that measures with my TDS meter at 20-40 ppm. Not perfect but usable.

    Your mileage may vary, and most boats aren't set up to be able to do this but I've had great success over the past three years using this approach. The system of valves and hoses also gives me many options for flushing and cleaning the system.
