Revitalize your ZTE flagship smartphone with this Li3939T44P8h756547 4000mAh replacement battery. Compatible with ZTE Axon 9 Pro (released August 2018, featuring a 6.21-inch AMOLED display, Snapdragon 845 processor, 6GB RAM, IP68 water/dust resistance) and ZTE Axon 10 Pro 5G (released 2019, 6.47-inch AMOLED display, Snapdragon 855 processor, up to 12GB RAM, 5G connectivity). The Axon 9 Pro original retail price was approximately $650 (€650), while the Axon 10 Pro 5G launched at 4999 yuan ($720). This Li-Polymer battery delivers the factory-rated 4000mAh capacity for reliable all-day usage. For reference, third‑party retailers sell certified batteries for approximately $22 to $26.
Built with Grade A Li-Polymer cells and multi-layer safety protection against overcharge, over-discharge, short circuit, and overcurrent. CE, PSE, and RoHS certified for safe transport and use. The battery supports QC4+/QC4/QC3.0 fast charging and Qi wireless charging — using the original charger supports Quick Charge 4+ for rapid power restoration. Professional installation is strongly recommended as the battery is not user‑replaceable.
Compatibility Note: Please power down your device and check your original battery label before ordering. Ensure the model number printed matches Li3939T44P8h756547. This battery is compatible with the above-listed ZTE models. The phones have an IP68 dust/water resistance rating — proper resealing with fresh adhesive is required to maintain this protection after replacement.
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 QC4+ fast charging performance, use the original ZTE charger that came with your phone. If you don’t use the device for a long time, store it in a dry and cool place and charge it fully once every three months. If you notice swelling or overheating, stop use immediately.

🔋 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.
