Restore the charging capability of your Huawei FreeBuds 3 charging case with this HB681636ECW 410mAh replacement battery. Released in 2019, the FreeBuds 3 features the Kirin A1 chip, open-fit active noise cancellation (up to 15dB), 4 hours of music playback per charge, and up to 20 hours total with the charging case. The case supports both USB Type-C (5V/1.2A) and Qi wireless charging. This Li-ion battery delivers the factory-rated 410mAh capacity. For reference, third‑party retailers sell this battery for approximately $13 to $22.
Built with Grade A Li-ion 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 reliability. Professional installation is recommended — the charging case is sealed and requires soldering for battery replacement.
Compatibility Note: Please check your original battery label before ordering. This battery is compatible with Huawei FreeBuds 3 charging case (model CM-H1C). The battery is not user‑replaceable — professional installation with soldering is strongly recommended as the case has a sealed design.
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. If you don’t use the charging case 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.

🔋 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.
