Whats wrong with my 02 Impala?

Could anyone tell me what might be wrong with my car?
I have had the alternator checked twice
The battery is only a week old
This video was right after an all night 2 amp trickle charge
ALL conncetions to the battery are clean and have bare shiny metal showing
All grounds for the battery are secure and the wires are not crackly

The car occasionally does start, but flashes the red battery light before leaving it on and then dying. If the car dies when its not running, that leads me to believe its not the starter, and the battery is new. The car does not even start half of the time, despite a fully charged battery, which tells me its not the alternator, plus the fact that I have had it checked twice in the last two weeks. Anyone got any ideas?

Check your batt connection wires first then if they are ok look at wireing harness or starter

It is ur security passlock. If it happen again watch the message board if it flashes security wait 10 minutes then try again

also check ur pcv valve, any vacum leaks may lead to it not starting, i have no idea why your playing with the headlights tho?
