Battery Issue Help Needed
I have a 2006 CLS500 that has had the Battery Symbol with the message "Visit Workshop" listed on the display for two weeks. The car has had 0 trouble other than the message. Yesterday I swapped the rear battery, the original battery was still in there. The message did not disappear and I fear the swap was a waste of $$$ 
Now I was about the switch the front aux battery but I finally wised up and took out the multimeter. Checking the front battery shows 6.3 volts both when the car is on and off. The rear new battery shows 12 when off and 13.4 when on. Again the car has zero issues so far. What should be my next step?
Change the Aux Battery?
Change the Relay?
Alternator?
Thanks
