Di2 Internal Battery
Previous battery would not hold its charge. I fitted the new battery a few weeks ago and its doing its job. Charge is holding.

Works great for DI2 but very expensive for what it is
Needed a replacement DI2 battery and this is an original shimano replacement battery which worked straight out of the box. Very expensive for what it is but what choice do you have.

Competitive price.
An expensive bit of kit but actually at a competitive price. It was a replacement for the original battery and so far so good.

Internal Di2 battery
Replacement as my external battery housing died. It's a battery it powers the system that's it really. It should come with a battery housing for the price they charge which is frankly excessive.

Lasted 14 months. Had to buy another.
Lasted 14 months of moderate use, and then gradually lost ability to hold charge. It the end it would go dead after 20 minutes of use. Very expensive; £10 per month of use. The Amazon warranty was for 12 months, so had to buy another.
