🔋 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 original flagship performance of your Huawei P20 or Honor 10 with this HB396285ECW 3400mAh replacement battery. The Huawei P20 was released in March 2018, featuring a 5.8-inch FullView display, Kirin 970 processor with dedicated NPU for AI computing, 4GB/6GB RAM, 64GB/128GB storage, and Leica dual cameras rated 102 points by DxOMark. Honor 10 offers a 5.84-inch display with the same Kirin 970 chipset. Both devices support Huawei SuperCharge technology — the 22.5W fast charger can charge the 3400mAh battery from 0% to 58% in just 30 minutes. This Li-Polymer battery delivers the factory-rated 3400mAh capacity for reliable all-day usage, restoring your phone’s original battery life and performance. For reference, third‑party retailers sell this battery for approximately $14 to $22.
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. With a cycle life of 500+ full charge cycles, this replacement battery is designed for long-term durability. The battery is not user‑replaceable — professional installation is strongly recommended as the device has a sealed back cover 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 Huawei and Honor models. The phone has no official IP water resistance rating (P20 does not have IP certification), 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 22.5W SuperCharge performance, use the original Huawei 5V/4.5A SuperCharge 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 Huawei P20 battery replacement. The Huawei P20, P20 Pro, and Honor 10 all have sealed designs with glass back covers secured by strong adhesive — the batteries are not user‑replaceable. The process to replace HB396285ECW battery in Huawei P20 requires heating to soften adhesive, careful prying with plastic tools to avoid damaging the 5.8-inch display, and proper reassembly. The phone has no official IP water resistance rating (only P20 Pro has IP67 certification), so water seal maintenance is not a concern for standard P20 after replacement. 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), and never reuse a battery after removal. Third-party repair shops typically charge $15-30 for labor.
