The fine print, decoded

What it leaves out

  • Accidental breaks and misuse
  • Batteries
Good to know before you buy
  • Covers the original buyer only. Keep your receipt; without it the store dates the battery from its code.
  • Take the battery to an authorized Interstate dealer, fully charged, so they can test it.
  • Using the battery in a commercial vehicle, a truck over one ton, or a diesel vehicle shortens coverage.
  • A battery that is just run down, not defective, is not covered.
