Default Voltage drop problem

Replaced battery and alternator recently, get 13-13.9v with car on. On my scan tool it shows the voltage at the control module is higher, but it doesnt output that amount. Checked all cables for resistance, wear and they are good.


Problem is battery drops instantly when car is off. Usually its 12.1-12.4v, but when I let it sit in the cold, its around 11.5-12v
