FranklinWH warranty for home batteries & power
The short version
FranklinWH doesn't cover everything, but keeps whole system and battery capacity covered to 12 years. That full coverage is the same as most of the 16 brands we compared, which typically cover nothing in full. Some of this coverage only applies if you register the product.
From FranklinWH's published warranty, checked October 2026.
