Changed my Di2 setup to the DN110 battery and new wireless port.

All good for rides outdoors I done over about 3 weeks. I'd say I rode every few days. I hadn't had to charge to battery from the initial first charge.

Bike now put away for winter. I am though using it for turbo work.

Here lies the problem.

I'd left the bike for 2 weeks and Went To use and found the battery to dead. Odd I thought. Never had this with old battery I could leave it months and a charge still be there.

Charged it and have left a week. Again the battery is dead.

Any ideas what could cause this? Wireless constantly on?

As I say never happened with the old btr2 battery.

It's a long shot, but any chance you're leaning it on a shifter when storing it? I've heard of people leaning their bikes on the wall and accidently having a shift button pushed in, which then prevents the system from sleeping.

Bike is stored in a bike stand. Good call though.

Do you have D-Fly? Many forget to close BT connection after updating with mobile.

Yes I do. Checked and bluetooth was turned on on my tablet but I had to connect to the dfly unit ( EWWU111) via the etube app so is it always on?

Do you have a D-Fly unit? Perhaps something is connecting to it via BT and keeping it from sleeping? Grasping at straws on this one.

i have the D-fly unit on an exposed area by the junction A. i remove it completely once i'm done with it, since i rarely use it for anything other than updating firmware.
