🔋 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.

Bring your Astell & Kern SR25 back to life with this PL685065 3150mAh replacement battery. Released in 2020, the A&norma SR25 is a premium high-resolution portable music player featuring dual Cirrus Logic CS43198 DACs in a dual-mono configuration, a quad-core CPU, and LDAC Bluetooth support for 24-bit hi-res wireless streaming. Its aluminum body and ultra-precision volume wheel deliver a truly premium listening experience, with up to 21 hours of continuous playback on a full charge. After years of use, the original PL685065 battery commonly swells or loses capacity — a well-documented issue in the audio community. This Li-ion Polymer battery restores the original 3150mAh capacity, bringing back the extended playback time and reliable performance the SR25 is known for. Built with grade A cells and multi-layer safety protection against overcharge, over-discharge, and short circuits. CE, RoHS, and UN38.3 certified.
Why This Battery Replacement Is Critical for SR25 Owners: The Astell & Kern SR25 is cherished by audiophiles for its neutral, detailed sound signature and long battery life. However, battery swelling is a widespread issue affecting the SR25 after 2-3 years of use. Symptoms include the back glass cover lifting, the player shutting down unexpectedly, not charging, or significantly reduced playback time. Astell & Kern does not sell replacement batteries directly and requires owners to ship the device to Korea for repair — costing approximately $102 and taking weeks. This PL685065 battery offers a cost-effective alternative, letting you restore your SR25 for a fraction of the official repair cost. The battery dimensions are 6.8mm × 50mm × 65mm, matching the original. Replacement is achievable for DIY users with moderate skills, though caution is required due to the delicate back glass and tiny connector. Many SR25 owners have successfully replaced the battery themselves using isopropyl alcohol to soften the T-7000 adhesive holding the back cover and the glue securing the battery to the aluminum tray. After replacement, the player typically performs like new, with 20+ hours of playback restored. This battery is also compatible with the SR15, the predecessor to the SR25, which shares the same battery design.
Compatibility Note: Fits Astell & Kern SR25, A&norma SR25, and Astell & Kern SR15. Please confirm your battery model before ordering — PL685065 is printed on the original battery label. This battery is NOT compatible with SR35, SA700, or other Astell & Kern models that use different battery sizes. Always check your original battery dimensions (6.8mm × 50mm × 65mm) before purchasing.
