Starter Battery
So I measured the voltage on my starter battery the one in the engine. It was at 12.1 volts, should be as around 12.5 or 12.6
Put my Ctek battery charger on it for 4 hours. The voltage went to 12.4. Drove the car around for about an hour. Measured
the voltage it was at 12.1 again, measured it later in the night it had dropped below 12 volts to 11.96.. Is this normal?
I don't think so, this car has 2200 miles on it. I had the AGM mode turned on the Ctek battery charger.

I seen this in CLS 257 forum. Seems like it's not just CLS. It's MB 450 in general

I finally convinced the dealer to replace my AGM battery in the trunk under warranty of course.
