Battery Life TIme

[zman]

Do you know the life time of the original battery that came with the car?
Isn't it 3 to 4 yrs?

The battery of my 2003 325xi has been working until today.
I don't have any problem or any symptom that it is going bad.

Should I not wait until it dies in the middle of nowhere and go head replace it?

Will a weak battery in BMW triggers other problems?

Thanks!

I had one battery in my 91 318is last over nine years, but yes the average battery life is 3-5 years. I would have the battery tested (load test) and avoid a breakdown in the wilderness.

3-4 years seems kind of short. yah- like big daddy suggested- go get the battery tested.

the battery in my 99 323i lasted almost 7 years (from summer 1998 - summer of 2005). it actually still had juice left, but i decided to be proactive. i bought a replacement battery from beverly hills bmw (lowest quote). it was slightly more than the price of a generic, but since it lasted almost 7 years i thought it was worth it. it's also very easy to install yourself.v
