Engine block heater vs. Battery Blanket?

So i thought this question would best fit in this section. For those of us that live in the frigid climates during the winter, what is everyone's opinions on keeping your Jeep nice and warm?

The cheaper of the two is the battery blanket, but, is the battery the better item to keep warm? Or is it the block being warm better?

Re: Engine block heater vs. Battery Blanket?

block is probubly going to work better. honestly i don't have either. my xj started like normal after sitting for three days in 20 below weather. my battery is a wally world cheapy becasue i didn't want it to hurt my yellow top.


Now i use the yellow top for my secondary for both amps, and the cheapy for my main.

I use no heaters and live in MN and make snowmobile trips to the UP of michigan to snowmobile. there good to have to cut warm up time in half.

Re: Engine block heater vs. Battery Blanket?

Thanks denny for the reply. As a side note, im more concerned about what would be better for the initial starting up of the vehicle rather than the time it takes to heat up to 195*. Once the Jeep is started ill let it run til its gets warm.

well a block heater heat the engine coolant only. some guys buy oil heaters but i would never because it kills your oil life. I have never used a battery warmer, but if the warmer would keep the battery warm throughout the night it would keep a full charge. so Ide guess teh battery warmer might work well. my dads ram has the plugin, he sets it on a christams light timer he likes that alot. starts perfect everytime. but he also has a yellow top in his.

Re: Engine block heater vs. Battery Blanket?

Thanks again Denny, it sounds like a battery blanket might be something id prefer. Im still waiting to hear from others who use these solutions also to see how they feel.

Re: Engine block heater vs. Battery Blanket?

My truck came with the bat blanket. I was interested in the block heater too. But the cars I've had in the past have done fine with starting in the winter. Now that I have a 4x4 with remote start I welcome winter to bring it!!! LOL

Re: Engine block heater vs. Battery Blanket?

Battery blanket will only protect the battery. When we get the -15 wind chill temps up here its takes a tole on the jeep and no remote start will make that first start up any easier.

I had a block heater in my xj and when it was in the negatives i would get in my jeep and it would turn right over and be at 100* on the needle.

I never used me remote start.

For the $35 for the block heater and the time to put it in or have it put in, i say engine block heater all the way. Then i would consider getting a battery blanket as well to keep the battery from freezing. But any good quality battery should not freeze, I never had an issue when i had my optima yellow top except for the fact that it only lasted 2 years before crapping out.

Re: Engine block heater vs. Battery Blanket?

interesting thread... i had thought (hoped) that since I had the battery blanked in my SRT that I would have had a block heater, but i've looked everywhere for a cord and can't find one... Oh well, it doesn't tend to get too cold here in Maryland (though this past winter was awfully cold).

Re: Engine block heater vs. Battery Blanket?

Well, the block heater is $35 and then its a matter of having it installed. it goes in a specific freeze plug in the block so it keeps the antifreeze warm. My 4.7 did not come with one but i bought a new one a while ago that i am going to have put in before winter and i am going to save my money and not get a remote start that justs wastes gas.
