Replacement battery for Astell&Kern AK300 and AK380

This lithium-ion cell is built to match the original 3300mAh 12.54Wh specification for Astell&Kern AK300 and AK380 media players. It delivers a nominal 3.8 volts and fits the exact 78.00 x 42.64 x 6.26mm footprint of the factory pack. A fully decoded chip ensures the player reads charge status correctly. The unit weighs 47.4g and ships in protective foam.

Practical limits of the battery interface

The pack uses the player's native connector and internal charging circuit, so no external adapter is required. Capacity reaches its rated 3300mAh after two or three full charge and discharge cycles. Operating or storage temperatures above 60 Celsius / 140 Fahrenheit can degrade the cell. Overcharge, over-discharge, over-voltage and short-circuit protection are integrated into the battery management system.

Check your device before ordering

Confirm the player model is AK300 or AK380 and that the original battery part number reads CP-AK380. Verify the connector orientation and cable length match the photos supplied with the listing. Ensure you are comfortable opening the player chassis or have access to a technician, as installation requires internal access. Do not use low-quality third-party chargers, as they may shorten cell life.
