1. Warranty Coverage Breakdown

Year 1 (Months 1 – 12): Full Replacement or Repair

In the event of defective BMS (Battery Management System), internal cell connection breakdown, or charger malfunction due to manufacturing flaws, PowHonhinen provides replacement components, official repair service, or direct replacement free of component charge.

Year 2 (Months 13 – 24): Maintenance & Parts Support

PowHonhinen covers structural components and key control boards (replacement BMS, baseplates, or wiring adapters). Customers are only responsible for actual shipping fees and consumable items.

2. Natural Battery Aging vs. Defect

Lithium-ion batteries naturally exhibit progressive chemical degradation depending on usage depth and cycling frequency.

  • Retaining 70% or more of initial rated capacity within 24 months (or < 600 full charge-discharge cycles under standard working conditions) is considered normal chemical wear and is not classified as a defect.
  • Permanent capacity loss caused by prolonged empty storage (< 0% state of charge for over 60 days) is not covered.

⚠️ 3. What Is NOT Covered by This Warranty?

  • Improper Installation: Reversed polarity (+/- swapped), wrong voltage pairing, or exceeding rated continuous BMS current.
  • Water Damage: Submersion, power washer cleaning, or prolonged deep water exposure beyond daily splash resistance.
  • Physical Impacts: Severe casing breakage, drops, collisions, or structural cracks from rough mishandling.
  • Unauthorized Modification: Opening the sealed casing, soldering, modifying internal firmware, or removing serial number seals.
  • Third-Party Chargers: Damage caused by chargers not officially certified, supplied, or approved by PowHonhinen.
  • Extreme Storage Conditions: Exposure to heat exceeding 60°C (140°F) or deep freeze without periodic maintenance charging.
