I just bought an 09 Silverado from my mom who has never had this issue but when I got it the battery kept dying overnight and I'd have to jump it every time I wanted to drive. Nothing plugged into the cigarette lighters, no lights on, nothing. Eventually the battery wouldn't even jump so I replaced the battery. All was good for about 3 weeks and a couple days ago I did end up leaving the dash cam plugged in for about 3 days but truck started up fine and I drove it for about 30 minutes, came back and unplugged everything again. Went out today (2 days later) and battery is dead again. Multimeter reads 5.1 volts on the battery. Wtf is going on?

what the voltage when it's running?
try having your alternator load tested at the parts store. It's free.

I'll jump it next time. On the dash the voltage reads about 14 when it's running but I haven't tested with a multimeter.

Use your meter to test current draw at the battery after the truck has been off a few minutes, then start pulling fuses to try to isolate the draw. Good luck.
