🔋 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.

Compatible with Huawei Watch 2 Pro 4G, Watch 2 4G, Watch GT, and Watch 2 Classic, this Li-ion battery delivers the original 410mAh capacity (typical 420mAh) and 1.53Wh energy — keeping your watch powered for a full day of 4G connectivity and continuous health tracking.

Built with Grade A Li-ion cells and multi-layer safety protection against overcharge, over-discharge, short circuit, and overcurrent. CE, RoHS, and ISO9001 certified for safe transport and use. The watch supports magnetic pogo-pin charging — a full charge takes approximately 100 minutes (1 hour 40 minutes) using the original charger. With a cycle life of 300-500 full charge cycles retaining 80% capacity, this replacement battery is designed for long-term durability. For reference, third‑party retailers sell this battery for approximately $21 to $39.

This battery is compatible with Huawei Watch 2 Pro 4G (EO-DLXXU), Huawei Watch 2 4G, Huawei Watch GT (LEO-B09), and Huawei Watch 2 Classic.

The watch has an IP68 dust/water resistance rating — professional installation is recommended to maintain water resistance 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 charging performance, use the original magnetic charger. 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.

Frequently Asked Questions

The HB512627ECW battery for Huawei Watch 2 Pro 4G is compatible with Huawei Watch 2 Pro 4G (EO-DLXXU), Huawei Watch 2 4G, Huawei Watch GT (LEO-B09), and Huawei Watch 2 Classic. The Huawei Watch 2 Pro was released in 2017 featuring a 1.2-inch AMOLED display, Snapdragon Wear 2100 processor, 768MB RAM, 4GB storage, and IP68 dust/water resistance. This 410mAh battery for Huawei Watch 2 Pro is a direct replacement for the original HB512627ECW battery. If your Huawei Watch 2 Pro battery replacement is needed because the watch drains quickly or won't hold a charge, this is the correct battery. Please verify your watch model on the back case and check the battery model HB512627ECW printed on your existing battery before purchasing. NOT compatible with Huawei Watch GT 2, Watch GT 3, Watch 3, or Watch 4 series.

The HB512627ECW 410mAh 3.82V battery has a typical capacity of 410mAh (420mAh typical) with 1.53Wh energy and a rated voltage of 3.82V. Charge limit voltage is 4.35V. It is a Li-ion battery built with Grade A cells and is CE, RoHS, and ISO9001 certified. The Huawei Watch 2 Pro supports magnetic pogo-pin charging — a full charge takes approximately 100 minutes (1 hour 40 minutes) at 25°C ambient temperature using the original charger. The battery provides up to 1.5 days of typical usage, or approximately 1 full day with 4G independent use. For best results, always use the original magnetic charger that came with your watch. The battery features integrated power management circuits protecting against over-voltage and under-voltage conditions.

Professional installation is strongly recommended for Huawei Watch 2 Pro battery replacement. The watch has a sealed design and is rated IP68 dust/water resistant — it is protected against dust ingress and can be submerged in up to 1.5 meters of water for 30 minutes (but NOT recommended for swimming or showering). The process to replace HB512627ECW battery requires heating to soften adhesive, careful opening of the sealed case using plastic tools, and proper resealing with fresh adhesive to maintain IP68 water resistance after replacement. Water resistance may be compromised if the watch is not properly resealed. If you choose DIY smartwatch 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 the display or internal components, and never reuse a battery after removal. Third-party repair shops typically charge $15-30 for labor, and IP68 water resistance may not be fully guaranteed after non-professional repair.
