✅ 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.

Restore the battery life of your Motorola Razr 40 Ultra with this PM29 + PM08 1 pair replacement battery set. The Razr 40 Ultra features a dual-battery design — two separate cells work together to power the foldable phone. This set includes both PM29 (2965mAh, main battery) and PM08 (835mAh, secondary battery), matching the original factory configuration. Built with grade A cells and multi-layer safety protection against overcharge, over-discharge, and short circuits. CE, RoHS, and UN38.3 certified.
⚠️ Important — Dual Battery Requirement: The Motorola Razr 40 Ultra requires BOTH batteries to function. This listing includes 1 pair (2 batteries — PM29 + PM08). For reference, Thai retailer Shopee sells this battery set for 1,415 Thai Baht ($40), and Spanish retailer All Spares for $9.10 plus shipping. Professional installation is strongly recommended — foldable phones have complex hinge mechanisms and delicate folding displays. Replacing batteries requires specialized tools and experience.
Compatibility Note: Fits Motorola Razr 40 Ultra (XT2321-2, XT2321-3) and Razr 2023. Both batteries must be replaced together. Please confirm your battery model before ordering — PM29 and PM08 printed on your existing batteries.
Installation Note: Due to the complexity of foldable phone disassembly, professional installation is strongly recommended. If you choose to DIY, watch multiple teardown tutorials before starting, use proper plastic opening tools, and never reuse batteries after removal.
Battery Care Tips: Avoid full discharge — keep battery level above 20%. Do not expose to high temperatures or direct sunlight. New batteries require 3-5 full charge cycles to reach optimal capacity. For best lifespan, use a certified charger. If you notice swelling or overheating, stop use immediately.
