The group size carries our verified badge only when the automaker's own battery chart and an independent retailer finder agree on it — two genuinely separate sources, never two resellers of the same data. CCA is shown as an OE minimum, a “choose at least this” floor, never a verified number, because the right CCA is a property of the battery you pick. Your owner's manual is always the final word.
