✅ 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.

🔋 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.
