Let my battery die about twice so far, almost completely, and now when I go to start the car in the morning it has to crank 3-4 times and take at least twice as long to start up.

Question: Could this be due to a weak battery?

 

If it is an older battery it can become damaged by completely discharging. I learned this the hard way in my youth while listening to tunes in the park from my Mazda 323 cassette deck!

 

yes. if you like draining your battery so much get an optima deep cycle battery.

 

time for new one before winter hits
