Engine dies while parked and won't start back up

[KrisKros]

When I'm at the parking lot with aircon on, and maybe park lights on and fog lamps on the engine will suddenly die after like 5mins of idling. Then it will not want to turn on when I try to turn the key. Headlights, gauges and everything is bright. I just hear a click when I turn the key. I have to wait like 5mins then VERRRY subtly i get some engine back..just enough to start up the engine. Or sometimes it won't even start up and I have to get a jump (yes automatic tranny hehe). What's wrong with my car? Any ideas guys? thanks so much.

-Battery is still ok
-I replaced my alternator just 2 weeks ago

If your car starts when you have the help of another battery through jumpstarting, then your battery is weak and needs replacement. Or your terminals need cleaning and retightening.

Thanks for teh speedy reply. Terminals are tight and clean. Battery should still be ok wouldn't it? When the car is "dead" after idling out.. my headlights are working and bright, horn sounds loud, gauges are bright.
I had this problem before I replaced my alternator..but it was worse before..The car could barely drive with aircon and headlights without dying. We replaced the alternator Then it was ok, we took it to Subic through NLEX and SCTEX without any problems.

your battery might have the voltage and capable of supplying small amount of current such as the headlight but insufficient to carry a heavier load for a period of time. try to check the voltage at the battery terminals while cranking the engine. chances are the voltage drops dramatically while you draw about 120 amps (1.4 kw divided by 12 volts). the voltage should not drop lower than 10.5 volts. if it does, your battery is retireable

ilang years na battery mo bro ?

Get a digital voltmeter and tingnan mo kung ilan volts while naka park ka.

And if dead na battery mo, change it to OPTIMA.
