Wire brush clean the battery posts and cables. There's a handy tool for this. Then start following the current. If you don't have one, pick up a decent multimeter (around $30 or less?) and check voltage at the top of the battery post. Should be around 12.6 or higher. If that checks out then I would check the current at big wire connection to your starter. You could also watch the current at the top of the battery while you crank it over.
It's also a good idea to check the battery negative ground connection. Remove it and clean it. You could Google the location of wiring harness grounds and check those too.
If the battery voltage isn't maintaining when the car is running then it may be either your alternator belt is worn or not tight enough or the alternator connections are bad or the alternator is bad. I prefer to get factory original alternators and starters rebuilt over buying new or rebuilt of unknown quality.
