Ok JFP, after three complete early morning cold starts (+/- 40 deg) I am happy to report how much better the battery feels while cranking the cold engine.
The equalization process did work out we'll see if this lasts until summer time, after all it's a four year old battery...

Good. 4-5 years is about an average life for many of these, so don't be surprised if it starts to fade again.

noob question......isn't the OEM battery on my '07 sealed? How do I check the electrolyte level and top off with distilled water if necessary? Thanks!

Not sealed. Just low maintenance. You have to "cut or break" through the black label on top, to access the 6-8 plastic screw caps. I forget how many cells there are. You can see the level on the sides, or look down the open hole. You'd be surprised how much distilled water these can take to top off when low!

Just peel the label at one of the corners to expose the six plugs, inside you will see a "small metal strip" that serves as a lever gauge, just cover the small 'leg' of the metal piece with distilled water. sounds confusing but it's pretty obvious once you look inside, just be careful and wear eye protection because you may get some splash back from the cell
