I’m doing a climb today and all of a sudden my Force rear derailleur goes dead. I recharged the batteries yesterday but several have gone from good to critical in a few minutes. The problems started yesterday but I just thought it was the batteries not being charged which is obviously not the case today
Have you checked to see if there has been any minor and perhaps not immediately obvious damage, to the main body on which the battery attaches?
It could be that a damaged or loose connection is manifesting as loss of power even though your battery is charged?
if you go by the SRAM advice, you should scharge the batteries and let them removed for couple days and see if they are still charged or dead. If dead, the situation is clear. If not the issue is somewhere on the path between derailleur and shifters, which causes the issue. usually it should consume energy only if the DR senses any movement.
Also I would check the controller batteries (CR2032?), if they are still good and replace proactively.
Unfortunately I have no solution to give you for this particular problem, but I low sided at 65kmh a few days ago and the only thing to eat sh*t besides my body was my Force D2 derailleur. The derailleur hanger didn’t even have a chance to bend, but the fall completely crushed the derailleur arm and mechanism. Managed to ride it 40km back home, but it was clear that i had lost 10, 11, 12. I spent the next day and a bit meticulously dismantling it and trying to bend it all back together before throwing in the towel and ordering a new one.
Anywayssss… My take away from this experience has been that, removing the battery terminal to access those prongs is a real PITA. There are 2 small torques screws, then to pull off the cover you need to remove the clip that holds the battery in place which is clearly engineered to prevent people from doing that. Unfortunately to make matters worse, you will need to also remove the cover for the actual servo mechanism to disconnect the wiring harness since it’s inaccessible from the outside. Overall the build quality of these derailleurs is OK (i mean, it got me home!), but they are a real nuisance to work on, which i think is (frustratingly) deliberate. I contacted SRAM to order replacement parts but haven’t heard back, and i doubt they’ll respond with anything meaningful.
Maybe you can grab the sunken terminal connector with a pair of pliers and try to pull it back out. The chipset behind may have just come loose, which unfortunately necessitates you dismantling everything to try and glue it back in place.

I found this fix for the eagle derailleur but taking that apart seems eas5

Had the same problem. My bike shop did send it back to sram and they replaced the pin for free.

Hopefully they will honour warranty, mine ran out 5/6 weeks ago

If not it try putting a dot of solder on it.
