🔋 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 enduring battery life of your Huawei flagship smartphone with this HB436486ECW 4000mAh replacement battery. Compatible with Huawei Mate 10 Pro (released October 2017, featuring 6.0-inch 1440p display, Kirin 970 processor, IP67 dust/water resistance), Mate 20 (October 2018, 6.53-inch display, Kirin 980), P20 Pro (March 2018, Leica triple camera), and Honor View20 (December 2018, 48MP punch‑hole display). This Li-Polymer battery delivers the factory-rated 4000mAh capacity for reliable all-day usage, supporting Huawei‘s 22.5W SuperCharge fast charging technology.
Built with Grade A Li-Polymer cells and multi-layer safety protection against overcharge, over-discharge, short circuit, and overcurrent. CE, RoHS, FCC, and UN38.3 certified for safe transport and use — complies with all operational safety directives applicable within the territory of the EU member states. With a cycle life of 500+ full charge cycles maintaining 80% capacity, this replacement battery is designed for long-term durability. For reference, third‑party retailers sell certified batteries for approximately $20 to $35.
Compatibility Note: Please power down your device and check your original battery label before ordering. Ensure the model number printed matches HB436486ECW. Professional installation is strongly recommended as the battery is not user‑replaceable. Please note that the phone has an IP67 or IP53 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 22.5W SuperCharge performance, use the original Huawei 4.5V/5A or 5V/4.5A charger that came with your phone. If you don’t use the battery 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.

Frequently Asked Questions

The HB436486ECW battery for Huawei Mate 10 Pro is compatible with a wide range of Huawei and Honor devices. Compatible models include Huawei Mate 10 (ALP-AL00, ALP-L09, ALP-L29), Mate 10 Pro (BLA-L09, BLA-L29, BLA-A09), Mate 10 Lite, Mate 20 (HMA-L09, HMA-L29, HMA-LX9, HMA-AL00, HMA-TL00), P20 Pro (CLT-L04, CLT-L09), P30 Pro, Mate X (ALP-AL00), Honor View20 (PCT-L29, 48MP punch‑hole display, 6.4-inch screen), Honor 20 Pro, Honor V20, and Huawei Nova 5Z. The Mate 10 Pro was released in October 2017 featuring a 6.0-inch 1440p display and Kirin 970 processor. The Mate 20 features a 6.53-inch display with Kirin 980. The Honor View20 features a 6.4-inch punch‑hole display with Kirin 980. This 4000mAh battery for Huawei Mate 20 is a direct replacement for the original HB436486ECW battery. If your Huawei Mate 10 Pro battery replacement is needed because the phone drains quickly or won't hold a charge, this is the correct battery. Please verify your device model in Settings > About Phone and check the battery model HB436486ECW printed on your existing battery before purchasing.

The HB436486ECW 4000mAh 3.82V battery has a typical capacity of 4000mAh (15.3Wh) and a rated voltage of 3.82V. Charge limit voltage is 4.4V. It is a Li-Polymer battery built with Grade A cells and is CE, RoHS, FCC, and UN38.3 certified. The compatible Huawei devices support 22.5W SuperCharge fast charging — when paired with the original 4.5V/5A or 5V/4.5A charger, the Mate 20 can be charged from 0% to 50% in approximately 28 minutes and fully in about 90 minutes. The battery also features overcharge, over-discharge, short circuit, and overcurrent protection. For best results, always use the original Huawei SuperCharge charger and cable that came with your phone.

Professional installation is strongly recommended for Huawei Mate 10 Pro battery replacement. The Mate 10 Pro is rated IP67 dust/water resistant — it can be submerged in up to 1 meter of water for 30 minutes. The Mate 20 and P20 Pro are rated IP53 for splash resistance — protecting against water sprays and light rain. The process to replace HB436486ECW battery requires heating to soften adhesive, careful prying to avoid damaging the display or waterproof seals, and proper resealing with fresh adhesive to maintain the respective IP rating 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 water resistance may not be fully guaranteed after non-professional repair.
