Shimano Di2 Charger with Cord - E tube

The Shimano Di2 Battery Charger is designed to power and maintain Shimano electronic shifting systems, ensuring reliable operation of Di2 drivetrains across compatible road and internal hub setups. It provides a simple and efficient way to charge Shimano internal batteries used in Di2 systems.

This charger is compatible with Shimano systems such as Alfine Di2, Dura-Ace 9070, R9100, and Ultegra 6870/6770, supporting a range of electronic shifting configurations. It is specifically designed for use with Shimano internal batteries including the SM-BTR2 and BT-DN110/BT-DN300 series (depending on system compatibility).

The SM-BCR2 charger connects directly to compatible Shimano junction boxes or display units and includes a USB power adapter (SM-USB1), allowing convenient charging via standard USB power sources. It also supports firmware updates through Shimano’s Di2 system when connected to a computer.

Proper firmware synchronization across all Di2 components is required for correct system operation, as mismatched versions can lead to communication issues or malfunction.
