Replacement Battery for Cowon iO M3 and X5

This Estry lithium cell replaces the original battery in Cowon iO M3 and X5 portable players. It matches the 3.7V voltage and 1100mAh capacity specified for part numbers PPCW0401 and PPCW0504. The 1-pack delivers a direct drop-in fit for restoring runtime on those devices.

Upgrade from Degraded Original Cells

The jump is worth it when the factory battery no longer holds a charge or shows reduced playback time. Swapping in this new 1100mAh unit restores the original capacity without requiring hardware modifications. It is not for buyers who need higher capacity than the stock specification or a different voltage.

1100mAh Capacity for Standard Playback

The 1100mAh rating supports typical music and video playback sessions on the compatible Cowon models. It runs out during extended high-volume use or when the player is left in standby for long periods. The cell measures 50.0 x 34.3 x 5.5mm and weighs 47.0g, fitting the original battery compartment.
