## Questions & Answers

**Q: The photo looks like it shows the battery cap with the hinge on it, instead of a flat top that fits into the charger.  Is the photo accurate?**
A: This is the correct picture. There is not a hinge or cap on this battery. There isn't any flat area. There are spots on the bottom that allows it to slide on rails to connect to the base.

**Q: Does this include the bracket? I need just the battery.**
A: It has been awile since I bought this but I am pretty sure I only got the battery not the clamp. I did not need the clam either.

**Q: Compatible with ultegra 6770  di2? and i’ll need to purchase external mount too? switching di2 internal to external...**
A: Yes, I have the 6770 series ultegra but mine came with the external battery holder, works fine for me.

**Q: how do i get the battery out**
A: There’s a latch that flips out, usually on the non-drive side. Then, there’s a small button to push in to release the battery. The battery slides up once released.
