For unknown reasons today my battery decides to die. I didnt leave anything on. Ive had it since Dec of 08. (Autolite brand but still under 3 year guarantee) So i got a jump to get home.

Then i noticed that when i open the driver door, it immediately locks itself when i open it. Thats never happened before with a dead battery or when ive disconnected the battery before. I can even try to open the door sometimes, and if i dont open it fast enough it locks and only opens halfway (still latched so i cant open it)

I tightened all of the cables and grounds that i could get to because its raining.

Any ideas?

 

does your truck have an alarm on it...i know alarms start to do weird stuff when a battery is dieing

 

Yeah it has an alarm, but what would that have to do with the doors locking themselves?

 

When I took the battery out of mine It locked the doors on me. And to make sure I did it again and it locked them.

 

I just replaced my factory batt (8 yrs old) Cause it started cranking slow ect. When I would start my truck both doors would lock on me. Some batts now a days wont last but 2-3yrs. Go get you a motorcraft with the 5yr replacement.

 

I don't understand how everybody is having so much trouble with their batteries lately. I've still got my stock one in there and it works fine and has no problems even in the cold weather.

 

i know my truck still has the original battery after 7.5 years...im on borrowed time with it though

 

Had battery checked today. Battery still reading good. Also had alternator checked. Thats fine.

I had it checked after i got it jumped and a few short minutes of driving. Would it be reading fine just because i got it jumped and drove it for a few minutes?

The gentleman told me that if it still died after a couple of days then it might be an electrical problem somewhere.

 

my doors also lock when i unhook the battery or it's if it's dead.but my mom has a 04 expo the battery died on,needless to say i replaced the connections,had the battery tested 2 times both times it came back good,so we just went ahead and bought a new battery never had a problem since then

 

i thought about replacing the connections, but i dont want to go through that just to have a crap battery.
