Chip Louie, my Gemini retro-kit is only 1 1/2 months old, so the battery is good. I should have removed the DSCH kit when I installed the Gemini, but was lazy and wanted to use Gem right away. BTW, mine are geared. I have been using the DSCH/Sky Commander on my GM-8 for years and still do. But it is time to remove them from the G11 and sell them.?
