Battery/alternator car wont start!!

Hey Guys!!

Boy I haven't been on here in a while. I've pretty much fixed everything on this car using the knowledge from this forum. (Thanks Guys!!)

From Changing the locks, to water pump/raditor, valve adjustment, to installing a grease kit.

well anyways, I got into an accident the other day.

Not much damage. Was able to drive the car back home.

Changed the oil, started the engine for a bit.

Then left the car for a couple of weeks. Tried to start the car and the battery was dead.

I used a portable battery jumper, the car cranks, but doesn't start...

the jumper reads check the alternator, and then is dead.
.....


What im thinking is that hopefully all the car needs is a new battery and that the jumper(cold starting 450amps) is just too weak to start the car.

Also, the battery indicator light always came on when driving.

Think a new battery has 850 cold starting amps

Anyways any help would be much appreciated!

thanks,

Tony
