Two different cold-start problems. A charger keeps the battery full; a blanket keeps it warm so it can deliver that charge at -20°F. If your car starts fine at 10°F but not at -15°F, the battery is probably fine and it's the temperature — blanket. If it's sluggish at any temperature after short trips, it's state of charge — charger. In the coldest places, outdoor-parked cars benefit from both, on the same outdoor timer.
Pick the Kat's if…
- ✓Outdoor parking where -10°F and below is routine
- ✓The battery tests healthy but won't crank on the coldest mornings
- ✓You have an outlet at your parking spot
Pick the NOCO if…
- ✓Short winter trips leave the battery chronically low
- ✓You want to maintain multiple vehicles
- ✓No outlet at the parking spot (charge in the garage instead)
