NH82W123. The parts store just checked the main battery. I will go back and have them check the Aux battery.

Chronometers: the car does have original battery (the car came with all the paperwork and I had the local MB adviser pull vehicle history before purchase) the history shows the battery has not changed, but does shows the battery charged in Germany; it was a North American European delivery vehicle.

Thanks for your responses and I will start calling Continental and Interstate distributors for a blemished battery and replace it.
