12V AGM. Easiest way to validate is go to a website that sells batteries like Interstate or Autozone, etc.

You have it set right. AGM battery selected, and 12v 2 amp. Never charge at the 12v 15 amp.

I use a CTEK at 4 amp charge, and it took about 5 hours to top battery off from approx half charged.

If you have volt meter check for charge never going over 14.7 volts.

My CTEK lowered voltage as it topped off to 12.75v.

BMW computer tries to keep battery charged only up to 80 %.
