How Does Cold Weather Affect The Vehicle Battery?

Winter seems to bring many issues from freezing pipes, high electric bills, to dying vehicle batteries. Do you often find that your car won't charge fully in winter?

Please don't rush to determine that the charger is working wrong. Most of the time, this is not likely due to the charger but more likely due to the battery, the weather, and driving habits.

Let us make an explanation as below.

Generally, at 59F to 95F( 15 ℃ to 35 ℃), the charging and discharging capacity of the battery is at a right level for 98-100%.

According to some reports, a car battery gets drastically more worn from winter temperatures. When the temperature lower than 59F, electrolyte in the battery will become thicker and the internal resistance in the battery will increase causing the movement of lithium ions to slow down. so its capacity will drop to 70% or 80%. Therefore, you charge it with Megear ev charger, you will find the charger stopped charge at 80% capacity.

On the other hand, when the temperature is low, the tire pressure of the car is unstable, which increases the friction and affects the endurance. The increased use of headlights and heater during winter days, these greatly increases the electricity consumption and reduce the car's battery life.

5 Things to remember about charging in cold weather:

  • Ensure interior car lights are all off before exiting the vehicle.
  • Maintain a warm battery. ( Betterat 59F to 95F)
  • When possible, store a car in a garage. Choose a relatively warm place such as underground garage, under the sun, your own garage to charge.
  • Get routine maintenance.
  • Prepare a portable Megear ev charger at any time during travel.
