my trucks battery often runs out. will the pad be warm for a while? or does the pad just shut off and get cold?

Runs off battery. Cool rate is variable depending on temp and misc Might try a space blanket with it

It gets very warm and stays that way for awhile. I turned it off and it stays warm for awhile

We found that once the chill was off we were warm enough except in really cold weather. We have had to run them all night when it was mid-winter.

We've used it all night, laying the warmer across the feet and leg area of a full/queen mattress, under our sleeping bags. We've turned it on to 2 or 3 of the dial that goes up to 8, and left it on all night, and it has not killed our truck battery. But it is a little slice of heaven, keeping the feet and legs warm!!

It will get cold but they work so well u will not need it on all night. The trick to staying warm with this heat pad is a thin blanket on top and a comforter to hold the heat in. I recommend this item for all drivers.

If the temp. rises too much the battery may overheat and boil away the electrolite. I would think that it should be turned off if the temp. stays above freezing for several hours I turn mine on at night and off in the morning if the temp. during .the day will be warner than 32 degrees.

Mine turned off when the car engine was not running. I don't know long the items will stay cool for. We only tested for six hours with no power. The food was cold.Hope this helps

Mine is now on its 3rd season and it's definitely lost a bit of power. Just read the instructions and follow them and it seems fine. These are lead acid batteries like in a car, so if you leave them in the cold and don't ever charge them, they won't work when you need them. I'm in Michigan, so cold winters are a thing. I bring the battery in for the winter and plug it in once a month like the instructions say and it's been going quite well. I assume next year I might need a new one, but 4 years of mowing with no gas doesn't seem too bad.

I live in northern NJ, where the winter temps range in the teens to low 20's. The tenders have kept my batteries fines for years. A college buddy lives near Fairbanks Alaska. He keeps his cars on tenders through each winter night to prevent the battery from freezing or going down. In the morning, he disconnects, drives to work, and then attaches again at their special parking lots. They are designed for heater and battery plug-ins.

Yep, I've had mine running all winter long. The unit itself doesn't get hot and once the room reaches the desired temp (set by you) it goes into power save mode.

It actually doesn't work like a regular heating pad. It comes with batteries that you recharge and put into the pad. So once the batteries run out you have to put them into the charging pod and not use the heating pad. A better choice would have been a built in pack that can charge and be used, like a cell phone battery.

I don't use a cooler pad and mine gets pretty warm. Note: I run Linux, which may or may not be a factor...

If it can't be plugged in overnight how long would I have to leave this plugged in for so that the engine is warm enough to start easily and not cause premature wear on the engine?

I bought this battery wrap because our temperatures really get cold, sometimes in the minus. It works well and I also have a electric connection for heating the oil pan which was factory installed on my 2001 Ford Crown Vic. My car is in a unheated garage all winter which I don't drive unless the roads are bare. Don't know if a warming pad would be better.

Works in the freeze you will be ok but if the car has the motor off the battery will go dow in less than 2 hrs , I used a booster strong and give me 2 hrs warm, never became hot but realy works , whith the enginer runs will be ok no problem .

Hi, it does shut down so it doesn't draw off battery power. I made mine I to a portable meter for installs and that saves my portable battires.

Mine got uncomfortably hot too while it was charging my truck battery back up. I set it on a brick and actually let a small fan blow on it (which surprisingly cooled it off) But after 2 days like that, it reached a point where it blinked green, and eventually went solid green. And once it went green it cooled off - presumably drawing far less current. I'd guess your battery is fairly depleted and must be given some time to charge back up. If you are concerned or feel it's a safety issue - call the company.

I purchased one back in the summer for the grand-daughter, so this is our first winter, but it is sitting out in our detached garage in cold Tennessee weather. It's hasn't been extreme cold yet, but you have given me an idea that I might put a folded up blanket over the back end where the battery is, just in case. Taking the battery out and bringing it into the house is not something I personally want to do. It might be an easy thing, but this 71 yr. old granny doesn't want that job.

Its been my experience that leaveing it plugged in after dark the charge likes to feed back through the carge controler and heat up why i dont know but it does i would reccomend unplugging it as soon as it gets daark just to be safe..it does get kinda hot!
