How Does the Battery Work?

Knowing how a battery works is key to understanding how cold weather can kill a car battery. Lead-acid batteries are the most common battery type. They have a plastic case that surrounds lead plates. Each pair of those plates is called a cell. The lead plates sit in a solution that’s a mix of water and sulfuric acid.

How does lead acid affect a car battery?

The lead plates store a charge through a chemical reaction between the metal and the surrounding solution. That reaction causes a build-up of lead sulfate, which gradually reduces the maximum charge that the battery can hold. Lead-acid batteries also naturally discharge over time. This gradual reduction — or the battery sitting unused for too long — can result in a lack of fresh charge and would eventually cause every battery to die or become so weak that it wouldn’t be able to start your car.

How does temperature affect lithium batteries?

The chemical reactions that take place inside a battery are affected by rising temperatures. Chemical reactions inside the battery speed up as the temperature of the battery rises. Higher temperatures have a number of consequences for lithium-ion batteries, including improved performance and storage capacity. According to a study published in Scientific Reports, increasing the temperature from 77 to 113 degrees Fahrenheit resulted in a 20% increase in maximum storage capacity. However, this increased performance has a negative side effect: the battery’s lifecycle shortens over time.

What temperature should a battery be charged?

Lithium-ion batteries, for example, may be charged and discharged at temperatures ranging from 32°F to 113°F (however if you operate at such high-temperature levels you do run into the problems mentioned earlier). Lead-acid batteries, on the other hand, may be charged and discharged in temperatures ranging from -4 to 122 degrees Fahrenheit. Understanding the charging temperatures that a battery can withstand is crucial. If batteries are not operated at an adequate temperature, charge uptake will be limited because ion combination will be delayed. High current can cause pressure to build up inside sealed batteries, resulting in explosions.

How much strength does a car battery lose in cold weather?

Everything slows down in cold weather, notably the chemical reaction inside your automobile battery. In fact, at 32°F, a car battery loses approximately 35% of its strength. And at 0°F, it loses up to 60% of its strength—but starting your engine requires roughly twice as much force.

What is the depth of discharge of a battery?

The depth of discharge (DoD) of a battery is the proportion of the battery’s overall capacity that has been used up or discharged. This DoD is directly related to the battery’s longevity and even the number of discharging/charging cycles it can go through, or, in a nutshell, the “cycle life.” The greater the frequency with which a battery is charged and drained, the shorter its life cycle. It is generally not recommended to completely discharge a battery because this drastically reduces the battery’s usable life.

What are the attributes of battery temperature?

As previously stated, the key battery attributes that are affected by temperature are safety, longevity, and performance . Temperature affects these metrics in different ways; for example, extreme heat affects a battery differently than freezing temperatures.

What happens when the temperature rises above the working range of a battery?

When the temperature rises above the functioning range of the cell, it can cause corrosion within the battery, whereas excessive cold reduces the plates’ ability to retain charge. The shift between the two extremes will then have more catastrophic impacts on both battery life and power cell lifespan.

How does a gas car battery work?

Gas car batteries are usually lead-acid batteries that produce a voltage by creating a chemical reaction between six cells made of lead-based alloy plates immersed in an electrolyte solution of 65% distilled water and 35% sulfuric acid. The chemical reaction between the plates produces approximately 2.1 volts per cell, adding up to 12.6 volts total when 100% fully charged. A battery that dropped to 12.4 volts is said to be at 50% charge, and at 12.0 volts is 25% charged. This is because a battery is considered fully discharged at 10.5%.

How many volts is a gas car battery?

The most common battery inside a gas car is a rechargeable 12 volts (nominal) battery, rated at between 75 and 125 Ah (amp-hour), which is the maximum amount of power measured in Amps that battery can supply in one hour.
