Shimano BCR2 Charger for Internal Di2 Battery
Is the Shimano BCR2 the Right Charger for Your Internal Di2 Battery?
The Shimano BCR2 is the correct charger for the SM-BTR2 and IBTDN1101 internal Di2 batteries, used across Alfine Di2, Dura-Ace 9070, R9100, and Ultegra 6870/6770 electronic drivetrain systems. It connects directly to the port on the internal battery, pushing charge through the system without requiring battery removal from the bike. The charger uses a standard USB power input via the included SM-USB1 adapter, so you can power it from any standard USB wall charger or port without needing a proprietary power brick.
The BCR2 is a system-specific tool, not a universal Di2 charger, so it's important to verify it matches your battery model before purchasing. All Di2 components on the bike need to run matching firmware versions to avoid malfunctions, and the BCR2 is also the interface used to update Di2 firmware via Shimano's E-TUBE software. For anyone building or maintaining a Di2-equipped road or commuter bike on the listed platforms, the BCR2 is a non-negotiable part of keeping the system charged and running properly.
