Nissan Repair: hard to start when engine cold and battery dead, nissan maxima, computer scanner

Question
Hi,there,I got a 1999 Nissan Maxima,now i have a problem that hard to start engine in the morning when the engine is cold,i have to step on the gas to start the car,however,after i drive a bit,it is easier to start;another problem is some times when i turn the engine off,i cant turn it on,there is no power at all,even lights!!I have to use booster to connect my battery for about 1 hour to get the power back, and the lights is blinking.I am think if it is electrical problem or the idle,cause i brought the car to a shop to check,there was no code can be read from computer scanner,so, what do you think?Any advice is appreciated!! Thank you so much!!!!
PS:my battery is new and just 2 months old

Answer
Peng,

Could be that the alternator is defective.  I would take it to Autozone or Checker and get a free electrical inspection.  They have a system that can check the electrical system for proper operation.  That will let you know for sure what is going on with the charge circuit.
