So I finally got all my di2 parts today and I went to test them before installing on the bike. Nothing. It turns out the battery was dead and when I go to charge it, the charge light comes on orange for about five seconds and then turns off. I got it from ebay and the seller was really nice and just said return it, but he also said he charged it up and even took a picture when it was green and charged. It has sat in my cold garage for three weeks, but otherwise there is no reason the battery or charger would not work.
Any thoughts? I don't have the connector to plug it into my computer. It seems like I might be missing something simple and would rather make it work than send it back.

Update: So it turns out the battery was not at fault at all. My lesson from this is that when you are playing with a hodgepodge of collected Di2 parts that you bought on the cheap, you have to be prepared to do a lot of troubleshooting
This is how it went. I bought the shimano analysis tool and downloaded etube (version 4.0.3) that lets you plug into the computer and updated all the pieces but it simply would not recognize the battery or battery holder. After a day or so of pulling my hair out I decided to try and download the older version that is available (3.4.5) and see what would happen. Well that version was able to recognize the battery and holder so I was able to update it to the newest version of the firmware. Once updated it started shifting when I pushed the buttons (not yet installed on the bike) Then I plugged it in and opened it up with the newer version and all the components were recognized. So I installed it and went for a ride a couple of hours later and it worked perfectly--for forty minutes. I figured I had not charged the battery enough but when I coasted back home and plugged it in, it would not recognize the derailleur and it said the battery was fully charged. I had to isolate the rear derailleur until it it was recognized and then I overwrote it again until the system recognized everything. At some point it said I should not use all those components together but once reinstalled, I rode on Saturday for nearly three hours without any issues.
And electronic shifting is awesome. On super hilly gravel roads and then paved rollers, being able to shift from the hoods quickly and effortlessly and to shift from the end of the aerobars is exactly as useful as I thought it would be.
