It's compatible with SM-BTR1 batteries used on Dura-Ace 7970 and Ultegra 6770 Di2 groups.

It's the SM-BCR1 model, which is the standard charger for these systems.

Just plug the battery into the charger, plug the charger into the wall, and let it top up.

This is an unbranded replacement, but it's spec'd exactly for Shimano Di2 external batteries.
