Battery blankets anyone?

[Jobi-Wan Kenobi]

Anyone live in cold climates and had any luck using a battery blanket? We've had 2 mornings here in a row of hellish cold temps (this morning was -25) and I had to replace my 2 year old battery today. The engine started yesterday but I do kinda wonder now if the cold was already taking its toll on the battery at that time. I can't help but wonder though if using a battery blanket would have helped prolong the life a bit.

Thoughts?

i knew a guy on a grand prix forum years ago, he was in the army in Alaska, so very cold. he had a battery warmer, block heater, oil pan pad heater as well as a trans pan heater on his car. and all that helped when it was neg degrees out, aka most of the time for him.

so yeah its worth it. a battery tender might also help keep it fully charged.

I have mine heat foil insulation wrapped and a battery cover I guess you could call it a blanket from a corvette
I do this due to hopefully help reflect the heat rather than cold, you could probably get away with a lizard heater, just get one long enough to wrap around it and then you can just tuck the cord in when you unplug it. I am assuming you have the block heater already? if not that's a easy add-on

Years ago, I worked at a coal mine in northern BC, the battery blanket save the truck many times. I would have synthetic oil, block heater and battery blanket. It was cold, truck door won't close cold, the battery blanket saved the truck

One of my trucks came with a factory one.
We have several days a year of those super cold temps and unless the battery is older it's never been an issue. But yjose super cold temps are when battery problems show up so it doesn't hurt to have one.
