Excellent sealing and reliability have been proven through repeated field tests in various riding conditions, including extreme temperatures, rain, mud, and cobble stone roads.

Using a hard wired battery system which is both light weight and accurate compared to current wireless technology (as a wireless system would require 4 batteries: one for the RD, one for the FD, and one for each shift lever).

The use of a single small and discreet battery is light weight, efficient and creates a robust and reliable system.

One charge can give between 1000 and 2000 kilometre range depending on conditions and front mech operation (as this is the main power drain).

Shimano Dura Ace/Ultegra Di2 Battery Unit is rated 4.9 out of 5 by 12.
Rated 5 out of 5 by danwebb2000 from Does what it should Charged it, put on the bike and away you go. Exactly as it should.

Rated 5 out of 5 by oblongomaculatus from when they're gone, they're gone? Bought this in anticipation of the day the battery that came on my bike no longer holds a charge, as I've noticed recently (after 4 years) that the number of miles before recharging has begun to reduce. It still does well in excess of the 600 miles Shimano claim (maybe I don't do as much shifting as some) but one day it will doubtless be worn out. As more recent Di2 systems have a different battery, housing it inside the seatpost or frame, it's possible this version won't be available then. Should that be the case, I now have a spare ready to go!

Rated 5 out of 5 by salmoliv from Just a battery The all electronic gear switch from Shimano is fantastic. Not sure what I can tell you about the battery. It's small, light and does the trick.

What grease is recommended for the electrical contacts on the battery?

Asked by: LoneWolf63
Shimano recommend you apply their protective grease to the battery contacts area to prevent water ingress and subsequent risk of corrosion. Sadly we don't stock this grease and I can only recommend you to Google 'SHIMANO Connector grease [DG 15]'. I hope this helps.
