My car wont consistantly start, and the battery won't stay charged

My car began to not start almost every other time i tried to start without being jumped and now will not start at all without being jumped. the battery won’t stay charged and I bought the battery brand new 6 months ago.

what is your car ? year, make, model , and milage

1987 chevy cavalier, over 100,000 miles

when it comes to side terminal batteries that are having trouble starting/ staying charged, I always suspect corrosion at the terminals. I will clean those before looking at anything else.

Thats what I hoped was the problem but I cleaned them when I started having problems and there isnt any corrosion.

Check your charging system.

Use a DMM to check for parasitic draw.
