I bought a 2005 new 2 years ago and for the last few months, the battery light has been tuning on for, at least, 20-30secs after the car starts from cold.

When I start moving the car, though, the light goes away.
Should I be worried about this?

 

battery covered under your 50,000 mile bumper to bumper warranty

 

it is the coils!

check you batt connections.. guessing the temp it changing up there.

Okay Swoope....I'll bite.
Why wouldn't this just be a battery that is getting ready to go(not holding much of a charge or loosing charge), but once the car starts all is fine because now you are running off the alternator?
And when it's run for awhile the alternator is re-charging the battery to some extent, but then bleeds off over time when sitting(loosing it's charge). Of course I'd check the alternator out as well at this point.

I realize what you are saying about the cold setting in, but................

 

how old is it?

my replacement mazda battery lasted ~3 years. my motorcycle battery just died at 5 years, but i have always used a battery tender jr on it. i think i got an extra 2 years out of it that way..

and to the point, at 2 years i doubt it is the battery, but the temp swings in arthurs area would make me check the cables first. as i think he is a bit of a tinkerer!

spam.

The battery is 2 year old, I guess --- it's the same age as the car, I hope.

In my other cars, batteries have not died or show signs of trouble until they are, at least, 3.5 - passed 4 yrs.

One more piece of info: occasionally, the light did pop up while I was driving on the freeway but only for several seconds.

Could the light be lying due to loose connection? So far, I have never had a lousy starting incident. not even once. Does this warrant taking in the car for check-up?
Any other 2005 showing these signs?

Some of you suggested that this was due to the colder weather. I do not think so because the light has been showing up all Spring and Summer of this year.

 

I opened up the battery cover and checked the cables and they seemed pretty tight and in good shape. I did not see any battery froths on the terminals and things looked nice and clean.

I did not see any color indicators displaying the status of the battery, though.
