What Are Common Myths About Cold Weather Auto Batteries That You Should Be Aware Of?

Common myths about cold weather auto batteries include the following:

1. Cold weather instantly discharges batteries.
2. All batteries perform the same in cold weather.
3. New batteries are immune to cold-related issues.
4. Running the engine will always keep the battery warm.
5. Jump-starting a dead battery in cold weather is impossible.
6. Battery chargers are ineffective at low temperatures.

Cold weather instantly discharges batteries is a common myth. It is not cold weather itself that discharges a battery but rather the fact that cold temperatures slow down the chemical reactions inside the battery. According to the Battery Council International, a battery can lose about 35% of its capacity at 32°F (0°C) and up to 60% at 0°F (-18°C).

All batteries perform the same in cold weather is also inaccurate. Different batteries have varying resistance to cold temperatures.
