Well, I went on a trip for 2 weeks so my 'stang wasn't running for that long, when I come back I find that I can't open the door with my remote and the car doesn't start. Is this common? I jump started the car and left the car running for about 3 hours and I haven't had a problem since but is my battery bound to die again or am I all okay? Just wondering if I should buy a new battery or not.

This happens to me too. You're not the only one. From what i know you can get the optima battery and you can have your car stored for six months or longer and it will start right up. Now everytime you listen to your stereo while washing the car it will drain the battery i know it's happened to me twice.

I had my car out of service for about 10 days. It had the alarm and the Dallas Speed Cal slowly drawing a bit af current. The car started, but the 1998 stock battery's eye was red. After a week of normal driving, the eye turned back to green. Seems to be OK now. If you don't have an alarm, might just as well disconnect the battery and it will probably last a bit longer.

if it's an older battery, replace it. newer cars have a slight drain on the batteries. if you plan on being gone awhile, disconnect the battery.

yes, it can affect the battery. If your car is going to sit in your garage for a while you should disconnect the battery. Or you could get an Optima, which can be left without any use for very long periods. Good quality battery by the way.

Optimas are good batteries, I prefer them, but like all batteries you can get a dud. Leaving a battery connected in any vehicle for long periods of time will drain it, some worse than others depending on the health of the battery and the health of all exposed connections as well as switches.

i have an optima redtop and it died after sitting for a week and ive yet to get it fully recharged with driving it for several months.
i was afraid it was going to totally drain the battery while i was installing my hypertech programmer- the voltmeter was bobbing down really bad.

while we're on the topic of optimas and such, should an optima battery be okay if it gets drained and then recharged? or will cells die in it as with wet batteries?

I have a yellow top, couldn't be happier, I had the same problem with my stock battery, i had car audio systems, i have a speed cal, the optima has never shown a sign of weakness so far.

There are so many things that can affect when a battery will die, just telling them to get a certain kind of battery is not the answer. Be sure to use the battery as per directed by the manufacturer. Keep the battery clean as even small amounts of dust ont he battery can cause a surface discharge that will drain a battery very quickly (ironically, it is easy to test for this condition).. also every car has a certain amount of parasitic drain on the battery just for the memory of the ecm and other components (lots of aftermarket components such as alarms or head units add to this original amount) of the car, some can be quite high, unfortunately, Ford has a reputation of being the company with the most parasitic drain. You can do some simply at home tests that will help you determine what actually happened, I would guess that after two weeks the parasitic drain just got to the car, but you may want to check and see if you have too much of it.
