Usually 4-5 complete drains is time for a new battery if things don't check out. Also, check the battery fuse to make sure it hasn't blown. The AAA guy could have put red on black and black on red. Who knows what can happen right? Plus if it is really dead a jump box usually will not do it. We have 1000cca jump boxes and need jumper cables on top of the jump box at times for BMW's. best of luck.
