Where this came from
  • Interstate Batteries 2023 Application Guide (BCI/Clarios feed — retailer finder, one witness) — source“Lexus • ES250 1991-90 V6/2.5L 35 360”
  • 1990-1991 ES250 is a rebadged Camry V20 (2.5L V6); period Camry/ES V20-class compacts used group 35. Could not independently corroborate beyond the on-file candidate + era platform; lowest-confidence Lexus resolution. — source“(ES250 V20 = Camry-platform compact, group 35 class)”

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.
