My 2010 Saturn Vue has starting problems

What is your question?

I purchased my 2010 saturn vue in march of 2017 and bought a battery the 2nd day. after about a week i had to start jumping my car every few days to eventually every time i need to start it I was jumping it. been a yr and 3rd battery. Something is killing my $200.00 batteries. checked alternator and starter. told they were fine. i can turn my key and have power and ALMOST start and lose power and sounds like battery to weak to start. wait a few minutes turn key again and cranks right up and starts sometimes with the jiggle of the key

What makes this problem better or worse?

new battery for a few weeks
