🔋 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 endurance of your Honor smartphone with this HB376994ECW 4000mAh replacement battery. Compatible with Honor 8 Pro and Honor V9 (models DUK-AL20, DUK-TL30), both released in Q2 2017 featuring a 5.7-inch QHD display, Kirin 960 processor, and dual 12MP cameras. This Li-Polymer battery delivers the factory-rated 4000mAh capacity — providing up to 18 hours of video playback, 30 hours of talk time, or 504 hours of standby on a single full charge. For reference, third‑party retailers sell this battery for approximately $20 to $30.
Built with Grade A Li-Polymer cells and multi‑layer safety protection against overcharge, over‑discharge, short circuit, and overcurrent. CE, RoHS, and UN38.3 certified for safe transport and use. The Honor V9 supports 18W fast charging (9V/2A FCP protocol) via USB Type-C — using the original 18W charger, a full charge takes approximately 1 hour and 50 minutes. The battery is not user‑replaceable — professional installation is strongly recommended as the device has a sealed design with strong adhesive.
Compatibility Note: Please power down your device and check your original battery label before ordering. This battery is compatible with the above‑listed Honor and Huawei models. The device has no official IP water resistance rating, so water seal maintenance is not a concern 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 18W fast charging performance, use the original Honor 9V/2A 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.
