I'm trying to have a leg up this winter as far as my car starting in these frigid temps. Last winter I had a few mornings where my car wouldn't start because the battery was too cold to start the GP. The battery at that time was at most a year old. Ive looked into battery warmers on Amazon and i'm wondering if anyone has any input on them.

For example:

Any other sugestions? I have looked electric magnet oil pan warmers but I don't think thats what I need.

I have a block heater in all my vehicles. Even when it was 0* out, running them for 4 hours before I left for work they'd be around 40* for coolant temps. Really makes a big difference on cold starts and warm up times. It would also melt off any frost on my hood and if I kept my vents on for the defrost it would slightly defrost my windshield.

Battery warmer would make your battery last much longer but a new battery shouldn't have any issue starting a cold vehicle.

If I had the ability to run a line out to my car I'd install a block heater. Would be nice to have the block warm on those freezing days. But I live in an apartment and can't do that.

What are LL's going to do when Electric cars become common enough that people need a way to charge them even if they are renting an apartment.

My srt-4s had the blanket from the factory. I removed them when I went big turbo. I honestly never noticed a difference. I think battery quality has more to do with it than anything. Didnt have any warmers on the cruze or elantra this past winter either. Both started right up even in -25 real air temps.

I had a block heater on my gasser expedition and I used it everyday I could that it was below 30*. They work absolute wonders, almost instant heat, saves abuse, especially on vehicles with aluminum heads and cast blocks, the expansion rate difference is crazy at those temps, you want everything to heat up as equally as possible.

For the smaller guys, they have circulation pump heaters, not only does it heat the coolant it moves it around your block and heater core. It doesn't work as well for us guys with 8 gallons to heat, but for smaller applications it works great.

Whats the CCA on your battery [MENTION=1396]Freebeer187[/MENTION]?! The battery blanket might be a cheap holdover until the battery takes a dump completely, but I'd definitely get a better battery next time around. I wouldn't think any later model cars should have any trouble starting with a decent battery.
