Duracell Ultra battery in 2007 RoadKing 

I forgot to update the battery situation. After batteries plus put a charge back in the AGM battery, it has been working perfectly with no problems. My suggestion is, that when you buy a new battery, open the box and be sure to check the manufacture date before leaving the store. Especially one that is pre charged in the box. I have been pleased so far with the performance of the AGM non-spillable battery
( Lead acid battery (new) should not matter as it has no electrolyte in those until they are purchased. Most you add the acid yourself. )
