Warranty: 10-year product warranty, the LG Chem is also covered by warranty for 3,180 cycles and the amount that is repaid upon failure is dependent on how many years it has been running. For example, in the first two years, a homeowner can expect a 100% cashback warranty upon the failure of their RESU. However, once the unit is three years old, LG will only replace 72% of the total purchase value.
