Most Popular Battery Heater for SUV

I ordered Saturday night at 10, paid for expedited shipping to ensure my part reached me by mid-week. I did not select overnight shipping. Item was delivered Monday. Excellent turn around time! Item functions as it should. I've ordered several times from etrailer, never been disappointed. I will continue to support etrailer.com

Already had one and it works great, really helps save your battery on cold days and makes starting/cranking speeds faster instead of the slow crank you get when your battery is cold, i consider it a must have for winter where we get to -20 easily. The last one I got was from another site and cost at least 20% more there, so definitely happy I could get the same product for cheaper here.

Just as advertised. This Kat's battery heater will be keeping the battery warm in a whole house backup generator for when it gets real cold here in northern Wisconsin. It's connected to a thermostatic switch that's set to turn on at 10 degrees.

Heats up well and keeps battery's warm, just the ticket for diesel pickup trucks on sub zero days. Combined with a block heater even the coldest mornings are no trouble.
