I live in northern Minnesota and have a Pontiac Grand Am.
It's very hard to get an engine heater in this car.
I got the battery wrap and it was easy to install.
Due to lack of space I had to remove the battery cables and hold down bolt. I pull out the battery and wrapped it and used the long twist ties to keep it on. Put the battery back in and bolted it down and put the cables bake on. Ran the cord out the grill and plugged it in.
Two days later it was 14 below zero (that was at 8 PM.)
I went out and put a thermometer on top of the battery and the battery was at 60 degrees.
Car starts every morning because the battery has more power.

We bought this battery wrap from Amazon because you could not beat the price (+ free shipping!). It works terrific! My 18 year old son has a 1992 Honda Accord and we do not have an extra garage for his car. After going through one morning of his car not starting we purchased the battery wrap. It works like a charm! We have had a horrendous winter so far this year in New England and his car has started EVERY SINGLE MORNING! Only catch is that you do have to keep an eye on the temperature at night because the instructions clearly say that if it is above freezing you should not plug the battery wrap in. Well, today it was 2 degrees and the car started right up! My son has never been late to school or work since buying this battery wrap!

I live in Minnesota and unfortunately I have to keep one car outside in the winter time. As any mechanic knows batteries lose a percentage of charge when they get really cold and won't allow the car to start. This wrap completely eliminated that problem, keeps the battery warm like it was 60 outside and our car started perfect every time even when the weather got below zero.

I live in the northern part of the USA where it gets extremely cold. The battery warmer is used for a standby generator for our home. It has a duty cycle once a week and during this past December 2010 with temps the 2nd coldest on record - the generator spun over with ease and started immediately. I included the thermostatic plug/switch - great combination. I would highly recommend this product and supplier.

Like clock work the temp dropped below 0, first night didn't have it installed, I had to jump start the car(Honda Civic battery 1 year old) installed thermal wrap (I was still able to use the battery tie downs) second night below 0 plugged up wrap, next morning car started no problem.

Can't speak on reliability, I only had it on for a few days and it has been below freezing the whole time.

I first looked into these types of products because I bought better ones (Kim Hotstart) for diesel engine-generator sets that I manage, but didn't want to spend >$100. I found the build quality to be surprisingly good (but not great) on these and was pretty easy to install. I measured the cord length and mine was only 3.5' (advertised as 4')and just barely reaches the grill on my car.

Just a quick note for anyone who may be concerned that 60/80W is too much for the battery at certain times of the year. I had this same concern (briefly). Look for a dimmer extension cord for lamps that will allow you to throttle down the power if you think you need to. Also, you should realize that the temps under your hood during operation are going to be much more than the highest temp that these things will reach just sitting there warming. I measured mine with an infrared thermometer at 115 deg F max (surface of the pad).

This is a great product. I was having trouble getting my tractor to start in the cold MN winter. I also bought this item and wrapped the battery. I also bought the Katz 100 Watt 4x5 Universal Hot Pad heater and stuck it to the bottom of the oil pan. From the day I installed them my tractor started like it was 80 degrees in the middle of summer. We had an extremly cold winter this year and my tractor started with no trouble everytime.

My son's 1997 Saturn has to live outdoors (Chicagoland), and last winter we had a couple of really tiresome mornings when it simply wouldn't turn over due to the cold. Purchased earlier this month from the listed vendor in NC, (very prompt shipping!) and installed.

Every car mounts their battery a little differently, so I can't attest to every vehicle, but for a Saturn SC, it works perfectly. This car has a stupid mounting bracket that bolts over the top in a sort of cradle. An enormous pain to unbolt because the nuts are in such difficult to reach places. The good news is that one does not need to use the flimsy twist tie provided in order to secure the wrap. A velcro system would make much better sense. Anyway, if your vehicle has a clamp type mounting system, this product does not need the twist tie.

As far as keeping the battery warm, it works like a charm. It keeps the battery warm enough so that snow will melt over the battery spot on the hood. Plenty of cranks even when outside temps have been in the single digits. Highly recommended.

I bought this from Autozone 3 winters ago as I couldn't wait 2 days for Amazon and this will be winter number 4. I have a dual battery tray with 2 batteries in my 1981 Jeep CJ7. I live in Grand Junction Colorado. I live in a apartment and my Jeep is about 60 feet away from my front door where there's a power outlet at my front door.

When the weather gets to freezing at night during the fall, I'll wrap the primary battery fully which allows the secondary battery to at least get one of it's longest sides warmed up when I plug in the Thermal Wrap. When Spring comes along, I take the wrap off of the primary battery, clean it with degreaser and store it for the next fall.

On days and nights 32 degrees or colder, I will run an extension cord from my apartment to my Jeep for about 2 hours at night, so 7-9pm and then when I wake up in the morning, I'll plug it in again for 2-3 hours ... 5am-7am/8am (depending on how cold it is outside).

WIth Jeeps and other vehicles that have little insulation, batteries freeze and because I have a 360 motor in my Jeep with a Cam and other stuff, my motor requires a lot of CCA's and a frozen battery, no matter how many CCA's the battery may be, the battery can't be frozen.

This has been the ritual since I've had this Jeep

This product has not broke. It's in great shape going into it's 4th winter. I advise a person to unwrap the battery once the nights don't get down to 32 degress or less in the Spring.

First impressions of the battery blanket was that it was relatively high quality. The cord looked pretty good. Not sure what people were complaining about in other reviews. It did not wrap all the way around my battery in my 08 Tundra. I wish it was about 4 or 5 inches longer. It would be perfect. The twist tie thing that came with it is a joke. I simply loosened up the battery holder and slid it around the battery, then tightened the battery holder down which secured the battery blanket to the battery. Pretty self explanatory. The instructions are printed on it but do you really need a "how to" on how to wrap something around the battery?!

Why only four stars? It doesn't get that warm. I plugged it in and let it sit for 20 minutes. I couldn't tell if it was on. I plugged it into a watt/amp meter tool and it measured about 70 watts which told me that something in it was sucking power ( a good thing). I then checked it again and felt that it was somewhat warm. I then checked it a few hours later and it was not that much warmer. Maybe I just expected more heat. Still good for what it is. I would by it again. Great for those cold nights when the bitter cold can suck the life from your battery. Protect your rig and throw one of these around your battery.
