Wrap this 36" long heater around your vehicle's battery to maintain its charge and to ensure that your engine turns over in the winter. Plugs into 125-volt outlet. Vinyl cover resists oil and acid.
Features:
Specs:
As the temperature gets colder, your engine not only requires more power to start, but it also receives less power from the battery. As you can see in the chart above, your battery's power drops to 65-percent of its normal capacity at the freezing point. At this same temperature, the engine needs 65-percent more cranking power than it would normally need in 80-degree weather. By using this thermal wrap on your battery you can ensure that the battery will maintain the same amount of power that it has in warm temperatures. As a result, your engine will get the cranking power that it needs to help ensure a successful startup.

I used this through a winter in the north where it regularly is at subzero temperatures. Truck always started without any issues. I also had heat pads on the oil pan and transmission that I bought from etrailer. At -40+ degrees the truck always started relatively easy.
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.
The battery warmers I ordered from etrailer was just what I needed to protect my boat batteries from the ice cold temperatures this past winter, since I couldn't store them inside. They worked perfectly with an thermal switch.
Thank you etrailer for a great product.
Very warm, your battery thinks it’s Jul y!
Jonathon at eTrailers help me verify this product would work in a 2013 Hyundai Santa Fe AWD 2.0T.
Installation was done by a 3rd party for free.
We've had days of -20 to -30 C weather a few times now this winter. Works as it should.
Great heater, works as advertised. Fit my 98 Jeep Xj perfectly. I bought it last year to try and salvage a week cranking battery when it was cold. Well, a year later I'm wrapping up the same battery for the cold months ahead! Save the strain on your bat with a Kat!
I've used these items during the winter for the past 5 yrs or so and have NEVER had a Battery a Failure or No Start with these. Just Purchased two more for a couple more vehicles added to fleet.
Block heater gets hot when plugged in not installed. It will burn your hand. The battery wrap does heat up nicely. I have not installed them but assume they will work just fine.
This company has been VERY customer friendly during the entire order process. The shipment was delayed and they contacted me personally with an alternative if I didn't want to wait for the original item. Item actually arrived sooner than expected.
Item worked as described and I would do business with them again.
Great product exactly what I wanted very good service
I will be ordering another soon
Thanks

Quick and great service. Item was what I ordered and works great.
Thanks for everything!
Your service is great could not beleave how fast it got to me. It works great and glad to have it . Thank you
I assume it works. Based on the product instructions I plugged it it when it was really cold and northern Minnesota can get really cold. I assumed the warmth could be felt on the outside on the bottom of where the batteries are, I think it was warmer, maybe? At the end of the really cold part of winter the batteries didn't freeze, so I guess it worked! It came when it was supposed to and came to my house. Previously, going with another company, it was shipped 200 miles away from me, what a pain.
When my battery heater went out on my Generac 20KW stand by generator, I used this heater from E trailer used thermostat and wire connector from old unit they were still good, Generac wants about $80.00 for new this is much more economical.

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.
Very good product. Worked fiawlessly. Used it for a re-conditioned battery which begins to freeze @ about 15 - 16 F. Kept it from freezing overnight on several nights. Also purchased a battery pad heater for another car with a slightly larger battery. The pad heater did the same thing perfectly. If you live in the northern parts of the US and want to use re-conditioned batteries (Epsom salt & distilled water) over the winter, these heaters are essential for protection from freezing. Thanks etrailer.
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.
Cust. service is top notch. Thank you for contacting the USPS to locate my package. It got their attention. They were reluctant hand it over. After speaking with the Postmaster we finally received our Kat's battery heater. Made in the USA. Thank you for your much valued time for all your wonderful agents in your customer service dept. Also, it was packaged very well & arrived in great shape.
We placed this unit into a Generac 20kw standby generator. Unit is controlled by a thermo switch on at 0 degrees F / off at 30 degrees F. Works fine to keep the unit ready for any power outage. We used a piece of 1/4" coated plywood between the heater and the battery to prevent overheating the battery bottom. This is the 5th similar installation. Others have been in service for 6+ years.
the heater pad burn out about 30 days after I installed it junk im not happy with that at all
