Kobalt warranty for car batteries & jump starters
The short version
Kobalt doesn't cover everything, but keeps whole product covered to 3 years. That full coverage is the same as most of the 12 brands we compared, which typically cover nothing in full. You don't need to register to get this coverage.
From Kobalt's published warranty, checked October 2026.
