96 EVO Posted April 26, 2023 Share Posted April 26, 2023 I've read several times on RV forums, once recently, of owners using the water from their dehumidifier to top up their batteries. In the coach today and had to dump my dehumidifier bucket. Thought.... why don't I test this liquid gold 😁! On my Total Dissolved Solids meter it read 0.16 Water from my fresh water holding tank was 0.05 Think I'll just stick with store bought distilled water, which tests at 0.00 2 Link to comment Share on other sites More sharing options...
TomV48 Posted April 26, 2023 Share Posted April 26, 2023 (edited) GOOD choice. I hated to think what grows in any exposed vessel of water, especially what grows in a machine. But I hope to never have to water an RV battery again. Save that store bought water for my C-PAP. Thank GOD for my AGM's and LiFePo's Edited April 26, 2023 by TomV48 Link to comment Share on other sites More sharing options...
96 EVO Posted April 26, 2023 Author Share Posted April 26, 2023 I had no intent of using it, just curiosity! I'm on CPAP as well, so always a few gal of distilled on hand. Link to comment Share on other sites More sharing options...
cbr046 Posted April 26, 2023 Share Posted April 26, 2023 I had been using distilled from the dehumidifier. I'll limit it to just radiators going forward. Thanks for the research. - bob Link to comment Share on other sites More sharing options...
