I'm wondering if I should try to start my car today, even if I don't need to go anywhere, or just wait until tomorrow. Will waiting cause more or less damage to the battery? I was thinking I should drive it around for awhile to rev up the battery but what if it won't start and I just drain down the battery for nothing. No garage. Thanks for your thoughts.

I bought a battery charger back in the 1990s when batteries only lasted a couple of years. I've had Toyotas starting in 2000 and haven't needed it since then. I just replace the battery when recommended. I do recall the nuisance of calling AAA when the battery was dead and waiting 2 hours for service because a ton of other people had the same problem. Cars today are just so much more reliable than before.

It's getting up to 43 degrees tomorrow so you could just wait.

It's always good to have a friend with jumper cables if you get stuck.

I have to go to Boston today so I will definitely test things out but I'm going to wait until were in the positive temps.

Just leave it alone. It's not even that cold out.

It will be fine provided it is already in good shape mechanically.

I didn't have a garage the four years I lived in Alaska. No vehicle issues.

It'll be fine. Starting the car now might hurt the battery more than help it. Was the battery already weak or are you just taking precautions?

Yeup I had the same thought. Go out in my bathrobe in -10 and one starts but not my 2006 TJ :(

I mean if you start it you'll want to let it idle for a while to recharge the battery. If the battery is old, it's likely dead and will need to be replaced anyway.

I'd wait. I HAD to go out yesterday and the battery died even though I had driven it pretty far. The alternator puts out like a champ and the thing still died.

When it's warmer the alternator can better keep up with the excessive draw caused by the cold. I had no other option but didn't realize my battery was "weak". It was working fine so long as the weather wasn't this cold, but then it was like... "Yeah, I ain't doin' this, man." RIP little battery... RIP.

Just let it sit. Diesel gets weird at low temps but gas is fine. If you're really concerned go grab some stabil.

You *could* go out to start your car naked in -10F weather.

As long as you're not hanging around outside you'll be fine. At -10F with 30mph wind you'll be fine for 5 minutes (Frostbite calculator says 9 minutes at that temp/wind)

Not that I'd recommend it, mind you. If you locked yourself out of your house you'd have a problem pretty quickly.
