Good to know before you buy
- Covers the original buyer only, and only batteries bought from an authorized Interstate dealer in the US.
- Bring the battery fully charged; the dealer tests it before replacing it.
- Keep your receipt; without it the date is estimated from the battery's date code.
- AGM marine batteries used outside boats or RVs get a shorter coverage period.
