Shimano BTDN110A1 Internal Battery Groups DI2 ETUBE 110A1 R, Black, 1

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

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

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.

Expensive but quality

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.

Item as described, quick delivery, very happy!!

You get exactly what is says on the tin. Bought this after my original battery unit died a sudden death. The updated model dn110A seem somewhat more effective in shifting the from di2 derailleur although it may be placebo. It is expensive for a smallish battery but the price here was the most competitive so would recommend.

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.

問題なく使える

Prodotto originale Shimano, prezzo in linea di mercato.

Leider viel zu teuer aber das liegt wohl an Shimano.

Toujours pas donné chez Shimano. La lecture fait peur, car ils parlent d'explosion de la batterie, sûrement du à la traduction qui est mal faite. Sinon, moi je l'ai installé dans le tube du guidon, pour économiser du câble, car ils coûtent super chère. Sinon, vous pouvez aussi le mettre sur un autre tube, sur le guidon, pour le désencombrer, sonnette, phare, compteur kilométrique, rétros, etc. Je l'ai utilisé seulement 1 an après, et ne s'est pas déchargé.
