I never disconnected the battery while the car was running, I shut the car off first

ahh ok good :) well charge it up if u don't drive it long trips and only once and while like 1 every 2 weeks if your battery is more than 7 year old than change it if not than charge it full to 12.6v and go from there. if your battery is newer than 6 year old and it dies every couple days than u have a draw. u need a amp meter to check for draw

he said he put in a new motor and alternator.
Chances are good you have a bad ground like rudy said. could be at the battery, could be engine ground, could be at the starter.
When you get a boost from someone else's car, their ground becomes your ground and you can start.
But you will need a meter, as said above, and you will need to check your grounds all around to the chassis.

i would first check the grounds and test your battery to see if a cell or two are dropped. 1 cell = 2.2volts, so even if one is gone your car will have great difficulty starting or even turning over.

yea i seen that he put a new alternator but i just seen "i disconnected the battery " just because it's new when i disconnect a battery when the car is running the cars see's there is no battery voltage so the alternator goes full tilt and can burn your sator .
anyways that's not his problem. when u are boosting the car where are u boosting it it sounds like i have a draw and it's killing your battery every couple days u have any aftermarket stuff in your car??
if u have a multimeter check your battery voltage and report back :)

I agree with supernaught - could be the starter on its way out, did you have the electrical tested when you b4 you bought new ones, I have seen soooo many people blow money on batteries and altenators, cause they don't take the time to have them tesed, or pay the $20 odd bucks for an AVR test when things like this happen. The AVR test will check how the batter, altenator and starter are working and effecting each other, its worth getting the test.
