Should a new battery start in -35 without being plugged in?

I thought I had my car plugged in last night but didnt. It was -35 last night. It turned over a bit but not even close to starting. I then plugged it in for three hours and it still start, maybe something wrong with my block heater?

Nonetheless I bought this battery about a month ago from CT. Should it be starting in this weather?

Do I take it back or is there anything I can do?

You probably drained the cell on that intiially attempt. -35 is hard on the battery and everything else. You pretty much have one shot if the battery has been sitting a long time.

It wasn't sitting too long. I mean I drove it a few days ago. Then tried it in the morning and it wouldn't start.

Get a load test at CT.
If it's defective, you'll get replacement.

You plugged in the block heater or a battery charger?
If it was the block heater then its probably just your oil/coolant/etc getting to thick to start. Oil etc gets very thick at those temps, esp non-synthetics.
If it was your battery then it could be a draw on it pulling it down, made far worse by the extreme cold. A charge will warm it up some by the process as long as it hasn't frozen..

Have you tried pressing the gas pedal while turning on the car? I had that work before on the second try after the car refusing the start on the first go. It sounds like you have tried multiple times so it may not even work for you. Definitely check it out at Canadian Tire.

-35 is hard on a car and it's components.

I would not think it's abnormal.

Yes, everything was probably just frozen up in the engine, block heaters are a must at those temps imho...

Yes it should start. I've started a car, although it cranked slowly, in - 35C or colder with 4-6 year old batteries even.

I just replaced the battery in my car in June with a 650CCA AGM. It started today in - 35C and cranked fast and hard as hell.

I say your battery is defective or bad quality. A lot of CT batteries are garbage compared to ones from Costco or WalMart

I brought it there already because I was having issues, they tested it and said it was fine.

Your engine is frozen solid in < -25c. I can hear a ticking noise from the block when I just plugged in the block heater. Synthetic oil in the engine? Remember ...

Did you actually get to see the test results? CT has been known to avoid honoring battery warranties

In comparison, WM and Costco don't even bother with tests. Keep receipt and bring in battery for replacement or pro-rated refund, no questions asked

How old is your battery? Has it ever been drained?
Do you regularly dive over 30min?
Do you regularly charge it with an intelligent charger?
If the women don't find you handsome, they should at least find you handy.
