✅ 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.

| 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.
