car will not start

What is your question?

last time I drove my car was about 3 weeks ago when it snowed .didin't drive it any more until 1 week later,and it wasn't starting.Put it on booster pack and lights gotten brighter,but made a knocking sound,but took of the booster pack and no sounds at all or lights.I'am thinking that the battery is drained,battery is less than a year old;6 months.thinking that it just needs to be charged. Am I right in this? I have a 1994 Olds cutlass Supreme S 3.1Lt

What makes this problem better or worse?

no
