cca 450 is it enough for this -30 weather?

[rach]

i cant start my car this morning, was in the garage, probably like -10
and i noticed my battery cca is only 450, is this enough?
battery is 1 yr old

[ThePenIsMightier]

It should be, but there are so many variables to consider.
A block heater will make a big difference and a battery blanket would likely be as successful. Combine the two, and a '77 Rabbit would almost start!

dont have block heater, or blanket
im having hard time starting the car even when i was just shutting it off for 5 mins...when its -20

You can destroy a battery of any age or capacity in this weather really easily. Short trips or small parasitic drains beat battery age or capacity.

Have I mentioned that battery chargers are more important than block heaters in cold weather?

03 Suburban, 313,863km, 800CCA for the win, outside and not plugged in.

I’ve got dual 800s in my truck but I doubt it will start tonight without being plugged in for at least two hours. When I picked it up yesterday I had to boost it with a big Noco, but it has only moved 180km in four weeks and had an electrical draw which pulled the batteries down while an alignment was being done.

Will a vehicle start is entirely situational really.

Oddly enough, my sister is having starting problems with her car and battery was weak as well and its a Honda Civic. Maybe Honda Civic tings

Lots of modern cars have parasitic drains, so the need to maintain your battery is higher than with @speedog 2003 Suburban.

I suspect your battery has been frozen and is destroyed. You should have been charging your battery before now.

First step, bring the battery inside overnight. Then charge it with the charger, then take it to the parts store to get the battery tested. Take it back where you bought it if you have a warranty on that battery.

ok will do...its still at charging stage right now

[ExtraSlow]

Bring it inside and keve it a few hours at least. Charging a frozen battery is dangerous.

yup , car is already inside garage, its not heated, but its better than -30
so once its fully charged, i guess im able to start the car even with cca only being 450?

I've never plugged a vehicle in, in Alberta in my life. V8 FTW!

Just checked the specs - 450 CCA is typical for the 07 Civic. From what I gather, its not just the CCA alone that determines the relative performance of a battery in minus stupid.

On my Civic, I have always gotten the best battery possible - which usually is the Eliminator series from Canadian Tire (lasted 8 years in cold service then died suddenly in the summer).

Having said that, if you can fit a slightly oversized battery in the bay, I would also recommend this for more cold weather performance.

That size of battery is fine for that car. If you had to buy a replacement and there was a larger CCA option, and it still physically fit, it wouldn't hurt, but it also won't help much if you have some situation where the battery is getting drawn down in extreme cold weather.

Warm it up, see if it'll charge, but also, for real, get it tested at a parts store or Canadian tire. A discharged battery that has frozen is probably permanently damaged.
