When it gets really cold and I park in the outside commuter parking lot it tends to crank longer then normal to start... I wonder if this will help the battery if i plug this in at night in my garage. Thoughts?

Absolutely.

Battery performance drops like a rock in cold weather and most people's cars (ie over 90%) can't fully charge a battery. A fully charged battery in good condition (ie well taken care of with a low level of sulfation) should perform very well in extremely cold weather. As a bonus, batteries in good condition typically won't need to be constantly charged overnight in cold weather - just every week or two will be fine to top off the battery when it gets cold. To keep your battery running in good condition for as long as possible, charge the battery every few months in warmer weather as well.

An older battery in poor condition won't hold a charge as well as the battery is probably sulfated to a certain degree so charging it every night will do wonders to how well that battery will perform during the day.

Got it to replace my 2A smart charger WITHOUT the desulphate/repair mode.

Don't put much faith on the built in desulfate/repair mode... The mode basically does an equalization charge - applies a higher than normal charging voltage (typically around 16V) in order to equalize the charge across all 6 cells in a 12V battery for between 2 to 4 hours. This will recovery some capacity from your battery (especially the first time you run it) but it won't help too much for a sulfated (heavily or light... won't matter).

I recently purchased an used Kirkland battery that is 6 months old which was rated for 640 CCA but only measured 540 CCA after charging with a standard dumb 10A charger. I then charged it up a CTEK MXS 5.0 with a manually engageable recondition mode which does approx the same thing as the repair mode on the NOCO - I got 550 CCA after reconditioning it twice. In other words, not much changed as the cells were pretty close to balanced. In a Youtube video, someone else used a similar CTEK charger's recondition mode on an older battery and it recovered 200CCA (about 1/4 of the original capacity) from that abused battery so the mode does work in certain situations.

Now you might be thinking that my battery is defective... Well, I used a desulfator which I built from a kit off of e-Bay for $12 US Shipped, ran it for 4 days (96 hours...), and the battery now measures 640 CCA so about 20 CCA per day.
