Restore the charging capability of your Bang & Olufsen Beoplay E8 charging case with this AEC643333A 560mAh replacement battery. The Beoplay E8 charging case (1st Gen) originally contains a 365mAh battery, capable of providing 2 additional full charges for the earbuds — a total of 12 hours of playtime. This high‑capacity replacement battery upgrades your case’s original capacity while maintaining the same compact fit, allowing you to keep your premium wireless earbuds charged and ready for extended listening sessions. For reference, third‑party retailers sell this battery for approximately $15 to $30.
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. The Beoplay E8 charging case supports USB‑C charging — a full recharge takes approximately 2 hours. With a cycle life of 500+ full charge cycles, this replacement battery is designed for long-term durability. Professional installation is recommended as the charging case has a sealed design. Replacement requires heating to soften adhesive and careful prying with plastic tools — if you’re not confident, seek assistance from a professional repair shop.
Compatibility Note: Please check your original battery label before ordering. This battery is compatible with Bang & Olufsen Beoplay E8 (1st Gen and 2nd Gen) charging cases. May also be compatible with Beoplay E8 Sport (verify original battery capacity first). The case has no official IP water resistance rating, so water seal maintenance is not a concern after replacement.
Installation Note: This battery requires soldering — the original battery is connected via nickel tabs soldered to the circuit board. If you are not comfortable with soldering, professional installation is strongly recommended. A teardown tutorial is available online; search for “B&O Beoplay E8 charging case battery replacement” for step‑by‑step guidance.
Battery Care Tips: Avoid full discharge — recharge when battery level drops below 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.
