shimano battery

Hello, On last ride I had error E010 and the battery turned white/gray on the bottom, I also noticed a little dent on the side. Changed the battery, cleaned the contacts, updated last firmware and after some struggle seems to get rid of the error. Any thoughts?

Hi everyone, I was wondering if anyone had an issue with their internal battery unlatching from its mount after a big hit. I have a Devinci AC with an E8000 motor with an internal battery.
