Bad battery connector bolt

[vilant]

Was going to change my battery cables because I noticed some weird electrical issues (fading of instrument display sporadically) and eventually found the culprit was stripped bolts that connect the battery cables to the battery. After I saw how the cables disappeared under the car, I opted for plan B. Was able to push the bolts out of the old cables (new one was already loose) and just slid the new bolt in and tightened. Now the cables are tight against the battery and everything is back to normal. Here's the stripped bolt next to the new one.

Hopefully that solves the sporadic dimming dislay. Time will tell.
