Vehicle Cranks In The Cold!

I have had this maintainer hard wired onto my car's battery for about a month.
The battery is rated above the limits of the Noco 2D, but it does not stop the maintainer from keeping my battery topped off and operational in the cold weather.

I have the maintainer paired with a heated battery blanket, and engine block heater.
In cold weather (Fort McMurray), all three items are plugged into the block heater extension cord and run off a timer that comes on 4 hours before I need to leave.
With the maintainer installed, I have noticed that my vehicle cranks and starts more quickly than in years past.

I am a vehicle technician by trade, I understand the limits of this unit, and time required to charge and top-off batteries. This is a 2Amp trickle charger, and it's designed for 40Ah and under batteries. Most vehicle batteries will be way over this. If your vehicle has an excessive parasitic current draw, or your battery has come to the end of its life, this unit may not keep up (not it's fault).

I would say I am very happy with this maintainer, and would recommend it to anyone to keep their vehicle battery topped off and ready for those cold starts.

Yes, I recommend this product.
