✅ Why Our Warranty Stands Out
Unlike marketplace sellers with short buyer protection windows, we handle claims directly — no automated disputes, no endless back-and-forth.
| Compare | ✅ Qingsm Tech | ⚠️ eBay / AliExpress |
|---|---|---|
| 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.
