Non-Transferable Warranty This Limited Warranty applies solely to the original purchaser of the Battery and is non-transferable. Buyers should contact the point of purchase for any warranty claims.
Prorated Warranty Coverage During the first thirty-six (36) months of the Warranty Period, subject to exclusions listed below, if the Battery is found defective in material or workmanship, Sonny Power Co. will, at its discretion, provide credit, replacement, or repair of the Battery and/or its components. Beyond thirty-six (36) months, if the Battery is deemed defective in material or workmanship, Sonny Power Co. will repair or replace the Battery on a prorated basis.
