In case anyone runs into this…

After six years of faithful service, I started getting random, and false, "low battery" warnings on my rear derailleur. And it started to stop shifting unless I banged on it.

The culprit: the itty-bitty spring inside the contact pin was dead.

So I tore apart a spare charger to recycle a spring pin and busted out the soldering iron.

Good for another six years! (if the chassis keeps holding up)
