How do I start my car if my battery is too cold?
Make sure the radio, headlights, heater, etc., are switched to “off,” so they aren't pulling energy from your battery and engine. Now put the key in the ignition and turn it from the "off" to the "start" position about ten times. You're "cycling the key," which can help warm up the battery and starter.
Can a battery be too cold to start?
Cold batteries simply don't produce the same amount of power as warm batteries, and this effect can lead to starting issues. When it's cold, engine oil becomes thicker and doesn't flow around the engine as well. This means it's more difficult to pump through the engine block, placing additional strain on the battery.

Is my battery bad if it dies in the cold?
Drain #3: Freezing Temperatures Cold weather slows everything down, especially the chemical reaction happening inside your car battery. In fact, at 32°F, a car's battery loses about 35% of its strength. And at 0°F, it loses up to 60% of its strength—but your engine requires nearly twice as much power to start!

How to keep gas lines from freezing?
Keep your fuel tank full. Condensation on the walls of a gas tank will form and will eventually sink to the bottom and cause freezing problems in your fuel lines. It's much more difficult to start a cold car with a mostly-empty tank, so do yourself a favor and gas up often in the winter before letting the car sit.
How to connect jumper cables to dead battery?

Use a battery heater or engine block heater. In very cold climates it is common, and sometimes necessary, to keep a vehicle's engine block warm overnight. This is accomplished with an engine block heater, which plugs into an electrical outlet to maintain a warm temperature, helping the oil and other fluids flow more readily (this is particularly important for diesels). If that option isn’t available, you can try a plug-in electric heater for your battery.
What to do if you don't have a garage?
If you don’t have a garage, parking under or near something big can actually help. Park under a carport or tree or next to a building. The reason has to do with the physics of heating and cooling, and a car parked for the night in an open carport or under a large tree may be several degrees warmer the next morning than one parked out in the open.
Why do cars use carburetors?
Cars built before the mid-1980s usually used carburetors to mix small amounts of fuel with the air in the engine. Carburetors are very delicate instruments that often don't work well in the cold, particularly because tiny nozzles called jets get clogged with ice or because fuel didn’t evaporate well in them.
Why does my car have frozen fuel lines?
Reason 3: Cold weather can cause fuel problems. If there’s any water in the fuel lines (there shouldn’t be, but it happens), sub-zero temperatures can cause that water to freeze, blocking the flow of fuel.
