Genuine DI2 battery unit replacement
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.

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.
