You would loose considerable efficiency of that cell, but on the bright side all you have to do is drain the electrolyte, open up the cell and clean it off with a pressure washer, then reassemble and refill with fresh electrolyte.
Really... just where the F is carbon coming from? Its filled with KOH, the plates are Nickle and Iron, the only other thing involved in the battery is electrons. Where the hell is the carbon coming from to "Build up on your exposed plates"
the answer is that really NOTHING is going to happen to your metals in your FeNi battery when the plates are exposed except for the reduction of performance because the active chemical area has gone down because the plates are not fully submerged in the electrolytes... and YES. I own NiFe batteries. Also, I know the company, I know the battery technology very well. Using numbers I got from Iron Edison I calculated that you are going to have to spend 12% of your captured solar energy to run a distiller to make distilled water to replace the lost water in the NiFe batteries. You just can't put any water into the batteries, it MUST be distilled batteries.
