| Warranty Period | 90 days from delivery | 15-30 days from order confirmation |
| When It Starts | 📦 Upon delivery | ⚠️ Upon order confirmation (even before you receive it) |
| Claims Handling | We do it directly — email us | Automated dispute system, seller dependent |
| After Window Expires | Still can contact us for support | No recourse, seller can ignore you |
🔋 90-day warranty is the industry standard for replacement batteries. Batteries naturally lose capacity over time — this normal wear is not covered. Warranty applies to manufacturing defects only.
