Hi,
I just noticed that my battery is not fully charged. The battery indicator is black, not green. I have an old 12V battery charger.
Can I use this charger? Or should I buy the one from BMW?
If I can use it, is there a special procedure to connect it?
Thanks for your advice!

I would suggest the Battery Tender brand. The one from BMW is the same one just rebadged and more expensive, as Luigi said. Be sure to get the kind with alligator clips, not the kind that plugs into the lighter plug.

I got the Battery Tender, but it will never get the battery indicator to Green. I think you need a full size battery charger for that. I have one coming in today and hope to use it this weekend. My battery is actually new, but always had the black indicator. I have never had any starting or electrical issues, but want it fully charged anyway (I know I should of had it done when I got it new)
The BMW manual says to connect the charger at the points under the hood, but the Bently manual says standard battery chargers do not have "clean" power and that the battery should be disconnected from the car while charging, that's what I will do.

1.25A or smaller one?
If you have a smaller one that's probably the reason that it takes long time to fully charge.
I have this:
I hook it up at the front terminals and it usually takes overnight to see green.

Not bad but the same kind on Ebay is 1/3 cheaper

On the battery itself. I never really check
I'll check it tonight.
Edit:
I just researched around other forums.
The peek hole only shows one cell of the battery. So that cell has probably gone bad.
Or maybe you may need to add distilled water if your battery is not AGM.
