How old is your battery?

[artguy]

So I've seen battery questions lately which prompted me to check mine and see what type I have and how old it is...

...Original BMW, 8 years and still kick'n!

Of course now that I've posted this it will probably die

...and it was 13 years old at the time. No sense chancing it with another winter coming then. Have a 850 CCA Exide in there now and never a problem.

Alot has to do with the health of your starter... Old starter will strain and kill your battery faster... I just came to this conclusion this weekend... wondering why this E34 battery doesn't last long regardless of brand.

When you crank, it should be instant and fast cranking... If your BMW feels like no power when you first try and second time it cranks over just okay, then it is most likely your starter is on the way out... like mine. After this first crank on hot engine, starter kicks over like a champ. I am probably gonna wait for a sale before I pick one up.

Good starter use less amperage to turn over engine and bad one suck em all.

longest battery that we ever had was 2 years maye it has something to do with being sooo hot here

2 days old, do i win something? now that i've experienced the starter like it's supposed to crank, i realize the ac delco was near-death since before i bought the car this summer. i paid can$120 for a moll battery, a bit steep maybe but i'm already using the heated seats!

You are correct. Heat kills batteries. Cold climates cause the cells to lose power, but it comes back as temps warm up. Heat actually cause the plates to be destroyed.
