Questions & Answers

The photo appears to show a hinged battery cap rather than a flat top that fits into the charger. Is this a true representation of the scene?

This is an accurate representation of the situation. This battery has no hinges or caps. There isn't a single area that is completely flat. It can slide on rails to connect to the base at certain points on the bottom.

Is the bracket included in this? The battery is all I require. ?

It's been a while since I purchased this, but I believe I only purchased the battery and not the clamp. I also didn't require the clam.

Is the ultegra 6770di2 compatible with it? and I'll have to buy an external mount as well? Changing the internal di2 to an external di2. ?

Yes, I have a 6770 series ultegra, but mine came with an external battery holder, which I find to be sufficient.

What is the best method for removing the battery?

On the non-locking side, there's a latch that flips out. The battery can then be released by pressing a small button on the drive side. When you release the battery, it slides up.

It does not hold a charge after the first two months

3/5

A few months ago, I bought this batter. My previous battery had a five-year life span. Within the riding season, I would charge twice: once in early spring when I first got my bike out, and again in late August to get me through the fall. It kept dying on me this year, so I decided it was time to replace it. This is the one I bought, and I have to charge it every two weeks or it will die. It has now ruined rides for me, and I'd like a refund, but you can't contact the seller through this website.

It's a battery, that's what it is

5/5

It accomplishes the task at hand. This battery was purchased as a backup in the event that my primary battery failed. There isn't much to say except that it arrived exactly as described and functions flawlessly, with a slightly matte finish. My primary battery is operating at a much higher level of efficiency. To me, it makes no difference. My only criticism is the price, but aside from that, I would strongly recommend it to anyone.

Working and maintaining a charge are two different things

5/5

It's a di2 battery that appears to be in good working order and holds a charge. I'm at a loss for words!.

The battery was defective and would not hold a charge, so it was returned

3/5

They refused to replace or refund the item, stating that they would wait to see how the manufacturer (Shimano) responded before making a final decision. The matter is still in the works.
