Arrives before Christmas 
Wrap this 72" 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.

good product to keep the battery warm in severe winter climate
Great product exactly what I wanted very good service

Thanks
Works great, perfect size because i can only wrapped 3 sides anyway. Big difference when battery is on the weak side too
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.
Very warm, your battery thinks it’s Jul y!
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.
I installed this battery blanket right after I received it and had our first sub-freezing temps shortly afterwards. You can definitely tell the difference when cranking over the motor. Works as I had hoped it would.
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.
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!
The battery warmer gets quite hot it seems. I intend to run this without a timer overnight. Is this going to burn out running for 12 hours at a time
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.
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.
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.
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 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.
