DISCO 4 2014 TIME FOR NEW BATTERY
That is disappointing.
One interesting thing is CCA is actually starting power - i.e. it is about performance not capacity or more specifically the ability to start an engine in cold climates. You would have to do a capacity test to see what corresponding loss in AH rating you have also ended up with but I am sure this is also impacted.
I don’t see in their warranty guide where they state that they don’t provide a warranty for the starting power or performance. If this was explicitly stated then I guess you would think twice about buying in the first place.
