Where this came from
  • Interstate Batteries 2023 Application Guide (BCI/Clarios feed — retailer finder, one witness) — source“Chevrolet • Sonic 2020-12 L4/1.4L 47 525”
  • GM Genuine Parts catalog (parts.gmparts.com), genuine "ACDelco Gold 42 Month Warranty BCI Group 47 Battery" product page, "Fits these vehicles" Chevrolet tab — source“Sonic 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020”

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.
