🔋 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.

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.

Professional installation is strongly recommended for ZTE Axon 9 Pro battery replacement. Both the Axon 9 Pro and Axon 10 Pro 5G have sealed designs with IP68 dust/water resistance ratings — they are protected against dust ingress and can be submerged in up to 1.5 meters of water for 30 minutes. The process to replace Li3939T44P8h756547 battery requires heating to soften adhesive, careful prying to avoid damaging the display or waterproof seals, and proper resealing with fresh adhesive to maintain IP68 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 IP68 water resistance may not be fully guaranteed after non‑professional repair.
