Sean,

I am seeing some odd numbers. Would you diagnose for me?

It is a Dig220 with SC-60 that is close to five years old. I have never performed an acid clean of the blades until now. I had the low-Amp warning, so I cleaned the blades. Still get the low Amp warning and it shows .5A. The voltage went within minutes from 7v to 1v to 0v. Total amp hours is 51,400. Is a 0v reading a cell problem or a system problem?

It would seem obvious that the cell has reached the end of its life, but at $800+ , I would sure like to get another season out of it. What is confusing is that the outer blades show hardly any wear compared to the inner blades. Any chance of getting some more out of this baby?
