  • Interstate Batteries 2023 Application Guide (BCI/Clarios feed — retailer finder, one witness) — source“Chevrolet • Colorado 2012-09 V8/5.3L 86 590”
  • GM Genuine Parts catalog (parts.gmparts.com), genuine "ACDelco Gold 42 Month Warranty BCI Group 86 Battery" product page, "Fits these vehicles" Chevrolet tab — source“Colorado 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012”

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.
