✅ 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.
