Where this came from
  • Interstate Batteries 2023 Application Guide (BCI/Clarios feed — retailer finder, one witness) — source“Honda • Ridgeline 2020-17 V6/3.5L 48 620”
  • hondapartsnow_genuine_part — source“Honda Ridgeline Battery (H6/Fla) — 31500-TZ3-100M, 2017-2019; and Battery (H6/Agm) — 31500-TZ7-AGM100M, 2020-2026 Honda Ridgeline”

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.
