Changing SRAM eTap shifter batteries...who knew there was such a thing?!

After putting freshly charged SRAM eTap batteries in the front and rear derailleur, my left shifter wouldn't recognize the rear derailleur. Meaning my right derailleur would work, putting the rear derailleur in the smaller gear. I couldn't change the front derailleur because you need both the left and right shifters, and I couldn't put the rear derailleur in the larger gear because the left shifter wouldn't work... I was lost! I did some research and found out that the left and right shifters have their own batteries (size 2032). Here's how to replace those.

Your video saved my ride today. Like you, I had no idea the shifters are battery powered. Kinda obvious now, but hey, thanks a ton:-)
