4 cyl Altima s 2010
I brought her back from the dead, was left to rot for 2 years over the compressor having too much pressure to start her
New compressor and starter, and she still won’t start unless I use the jumpstarter
alternator is okay. Could it simply be the cheap crapa battery I bought? She starts dying if I use the rear window defrost and the battery shows 11 volts after being fully charged
would love to avoid looking for a wiring issue if it’s just the battery, although this battery is brand new. I hate electric and I have limited understanding on it
If the battery is only showing 11 volts after being fully charged it's shot. At 11 volts it's at less than 10% charge level.

alternator is okay.
how do you know?
if it's been trying to charge a dead battery for a while then it could be fried.
You need to load test both of them.
