I was without my main bike for a few months while it was being repainted. When I removed the components (SRAM Red eTap 11 speed) the battery life indicator showed green (eg charge good; I stored everything with the batteries removed from the derailleurs.
Fast forward to this week:
I built the bike back & the lights on the bike show red (eg needing charge). However, when placed on the charger, they show green.
I’ve previously gone over a year not riding this group & not had this issue. I’m currently letting the batteries sit on the charger for an hour in hopes it’ll alleviate the issue but I’m not sure I’m optimistic.
