Question about Mercury Milan
The battery is less than a year old. Two differnt auto parts stores tested the battery, starter, and alternator and they both said they tested good. Once you jump it off the car runs fine and will crank right back up. After sitting for over about 3 hours it does not crank. All the lights will come on but no start. Then is will at times give you a "check brake system" light.
This car MIGHT still be under warranty? Have you noticed if the brake lights are stuck on all the time? This sometimes happens when the switch on the pedal sticks or pops out of place.
Something might be draining the battery. A power seat switch can do it.
I'd take it to Ford and ask them if it's under warranty or service bulletin.They might fix it for free and at least they can tell you what's wrong. don-ohio (:^)

My '95 SL2 purchased new, ate 6 (SIX) alternators, that fantastic "27 patents" automatic transmission, two sets of front disks and finally dropped a rod cap at 56,700 miles of very civilized driving.
I 'sold' it to my youngest son for $1 as a hobby when he got bored with his Jeeps or to donate it to a fund-raising bashing contest.
Now, the reason the alternators die -
They are buried in the engine compartment and get hardly any natural cooling there and, I don't know what kind of stupid engineers GM employs these days, but that alternator at 105 amps rating must deliver up to 1200 watts of 12 volt power an d it is too small to effectively dissipate the 1200 watts of sheer heat it produces while doing it.
If you have any appliance that absorbs 1200 watts (10 amps at 120 VAC), just check to see how much heat that is and even if spread over a larger area and bulk of the alternator, you think that would be a good environment for the semiconductors that are used to make the DC and regulate it.
It's a absolutely insane design and convinced me to never, EVER buy another anything from GM!
Sorry to vent but it still irks me after over 4 years of trouble-free Subaru ownership.
I wish you luck.

For the Brake light to stay on and the fluid is up...sounds like your sensor is playing dead......
For the battery to die after only (4) hours..you have a very big drain on the battery itself.....without the vehicle right here to look at would be very hard to even guess...electrical problems are a hands on chore...
I'd take it to your garage/mechainc

Check operation of auto transmission neutral switch; if that is not faulty check 'Start' output from Ignition sw (or start slave relay) is OK;
If all above OK check for faulty starter motor operation.

SOURCE: my battery light is on
Sounds like your voltage regulator is acting up, and at times will not let alternator voltage reach the circuit. At this point car stars drawing on battery alone (triggering battery light) and working until it is out of juice. Before you buy a new voltage regulator, make sure that its contact points on the alternator, and the plug from it to the vehicle circuit is clean, shiny and making good contact. These parts, due to their location tend to collect dirt and moisture, leading to an intermittent performance before they stop working completely.
