Di2 over the winter - fully charge or other?
Winter is closing in on my part of the world. As a fair weather rider that means my bike won't be seeing much action. For the winter months, what's the recommended approach for bikes with Di2? Fully charge the battery before putting the bike away? Leave the charge as is and check it regularly for drainage? Other?

just as you would treat a fine exotic car in storage, you need to put it on a trickle charger.
Also you should make sure the bike doesn't sit on the ground to avoid flat spotting the tires.
Remove all the grease from all the bearings, and you should be good to go.
Get a grip; its a friggin bicycle.
Charge the battery in the spring before you ride and it will be fine

I would be careful not to let the battery freeze -- keep the bike indoors -- and don't lean the shift buttons against anything. Otherwise, check the charge a day before your first ride in the Spring so that you'll have time to top up the charge. I wouldn't think any special precautions are necessary.

Ha. Well said @merlinextraligh I was reading your listing like a serious post until the end there!
Thanks @FlashBazbo. The bike will be kept indoors over the winter.

The correct answer is to invoke Rule 5 and keep riding the bike.

Whether you ride it or not, Li-ion batteries don't do well if you let them freeze solid. And whether it's Di2 or eTap, the batteries are crazy expensive to replace (~$100 a bike).
I live in the frozen north - in the winter I store my electronic shifting bikes where they won't freeze.

lithium batteries don't like sitting fulling charge or discharge, anything in the 20-80% should make them happy. They also don't like being really hot or really cold.

I agree take the battery out and keep it warm, in a partially discharged state. Keeping a li ion in a high state of charge accelerates parasitic side reactions that lead to loss of capacity. So does extreme heat.
however, I don't think keeping it in the cold is super harmful, unless you try to use it. electrolyte may freeze? Idk but still safe to just keep it warm

Our garage doesn't freeze, although it does get cold. I think whenever my riding stops for the winter there will be a good enough charge in/on the battery for it to last through until the spring when I start riding again. Good to know about the freezing bit though. I hadn't thought of that.
