Car as expected now starts quicker and you can hear the difference in the sound of the starter.
When driving, voltage readings on my radar detector use to swing between 14.2 to 14.8 (AC is off). Now when driving its a steady 14.6.
When the car was off and I had the accessory on (with heater blowing) the voltage would drop quickly to 11.9-12.0. Now it stays at 12.6.
For those that are interested, got this red top here and it came in 3 days. I did use the tray they provide under the battery to make it the same height of the OEM battery:

You definitely had a problem with the battery. My Radar Detector also tells me voltage (passport), and with the car off, it reads 12.6V.
