Car having trouble starting without battery boost. Brand new battery. on 2000 Volkswagen Jetta

So I went to start my car and it wouldnt start. I have lights and gauges, but when it comes to starting, its a no go. But when I hook up jumper cables or a portable battery charger it starts right up with no problem or issue. The battery is literally 2 days old and had been changed out just in case of a defective battery. So I went thru two new batteries and was told by my neighbor it wasnt the starter or alternator. So what?????

perform a parasitic drain test. There might be a system still getting power when the car is turn off.
