Title: Discoloration of cell fluid
Post by: Dgrblu on September 08, 2021, 08:13:07 PM
Eight six volt Crown CR-430 batteries, 2018 date code, wired in series for a 48 volt system.
I am beginning to see the electrolyte in the cell nearest the negative post turn brown after adding water. Appears to me that when I shoot the water in it stirs up some sort of sediment. Would this be normal?

Thanks

I'm not sure.  Someone else will most likely chime in with info.

I m wondering though if you usually use distilled water ?

Take a look here - they list a number of reasons.

Yes, the link was very informative.
The settings on the Classic 150 have not changed in the year that I have owned the place/system. Not frying them.  Water has always been where it needs to be. The batteries SG is all good. So being curious, I took a peak at the electrolyte while the Classic was resting and found all cells were clear. Having a bit of good timing, I later found the system in EQ mode so I took a peak at the electrolyte. All cells of all eight batteries the electrolyte was muddy color with floating swirling particles.
I'm now thinking that with the batteries being used for three years that there would be debris from the cells as they age.
May be being a bit of a worry wort..... :)
