How Mizuki Dual Warranty Operates

Phase 1: Free Replacement Period

100% Free Replacement

During the initial warranty phase (e.g., first 36 months for ENERRZA EZA series, or 15 months for RYDEXXX), if the battery develops an internal cell failure, short-circuit, or active paste degradation, Mizuki provides an absolute 100% Free Replacement unit through your nearest dealer.

Phase 2: Pro-Rata Warranty Period

Discounted Pro-Rata Settlement

During the pro-rata phase (e.g., months 37 through 60), the customer receives a substantial discount on the prevailing MRP of a brand-new battery. The discount percentage corresponds directly to the unused pro-rata tenure, protecting your initial investment.
