✅ 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.

Please verify your device model in Settings > About Phone and check the battery model RC30-0259 printed on your existing battery before purchasing.

The RC30-0259 4000mAh 3.85V battery has a typical capacity of 4000mAh (15.4Wh) and a rated voltage of 3.85V. Charge limit voltage is 4.4V. It is a Li-Polymer battery built with Grade A cells and is CE, RoHS, and UN38.3 certified.

Professional installation is strongly recommended for Razer Phone 2 battery replacement. The Razer Phone 2 has a sealed design with a glass back cover secured by strong adhesive and is rated IP67 dust/water resistant — it can be submerged in up to 1 meter of water for 30 minutes. The process to replace RC30-0259 battery requires heating to soften adhesive, careful prying to avoid damaging the display or back cover, and proper resealing with fresh adhesive to maintain IP67 water resistance after replacement. Water resistance may be compromised if the phone is not properly resealed. If you choose DIY phone battery replacement, watch a full teardown tutorial before starting, use a heat gun at low temperature (no more than 70°C), use plastic tools to avoid damaging internal components, and never reuse a battery after removal. Third-party repair shops typically charge $20-40 for labor, and IP67 water resistance may not be fully guaranteed after non-professional repair.
