, by Sally Zhuang, 10 min reading time

Whatever you choose to explore the great outdoors with your RV or enjoy some quiet fishing, converting your battery bank to lithium offers numerous benefits. But nature doesn't always go according to our plans and unexpected freezing temperatures can raise our concerns about battery performance. In this article we address the question: “Can lithium batteries freeze?”

Can lithium batteries freeze?

Unlike water or other liquids, lithium batteries do not freeze to a solid state. Although freezing temperatures can affect their performance, lithium batteries do not solidify or become inoperable when exposed to freezing temperatures. However, extreme cold can have an impact on their efficiency and overall performance. It is important to understand the effects of freezing temperatures on lithium batteries and take appropriate precautions to ensure their optimal performance in cold weather.

Are lithium batteries good in cold weather?

When it comes to cold weather conditions, Lithium Iron Phosphate (LFP) batteries are an excellent choice. Unlike traditional lead-acid batteries, which can be affected by low temperatures, LFP batteries provide reliable performance and durability even in extreme cold.

LFP batteries are designed to operate effectively over a wide temperature range, making them very practical for various applications, such as: b for off-grid solar systems, RVs and caravans where freezing temperatures are common. These batteries can operate safely in temperatures ranging from -20 degrees Fahrenheit (-4 degrees Celsius) up to 60 degrees Fahrenheit (140 degrees Celsius).

In contrast, the performance of lead-acid batteries is significantly reduced in colder temperatures. The capacity of lead-acid batteries decreases, and the more power you draw from them, the weaker they become. However, LFP batteries are great for cold weather conditions. When you use LFP batteries, they naturally heat up due to lower internal resistance, resulting in higher voltage and better performance.

If you choose lithium batteries, especially LFP, to meet your power needs in cold weather, you can overcome the limitations of traditional lead-acid batteries. With their superior performance, reliability and temperature resistance, lithium batteries, especially LFP, are the clear winner for powering your devices in cold weather.

Whatever you're upgrading an existing battery system or looking for a reliable solution to cold weather challenges, lithium batteries are an optimal choice. Experience the benefits of improved performance and expanded usability by adopting LFP batteries for your cold weather power needs.

Does cold weather affect the lifespan of lithium batteries?

Cold temperatures affect the performance and longevity of lithium batteries. Although lithium batteries are generally more cold-resistant than lead-acid batteries, extremely low temperatures can still affect their efficiency and capacity.

Lead-acid batteries significantly lose efficiency and usable capacity when exposed to temperatures below freezing (32 degrees Fahrenheit or 0 degrees Celsius). Typically they only deliver around 70-80% of their rated capacity under such conditions. In contrast, lithium batteries have minimal capacity loss and can deliver 95-98% of their capacity at the same temperature.

During charging, the lithium ions are normally absorbed by the graphite, which acts as the anode of the battery and has a sponge-like structure. However, when the temperature falls below freezing, efficient absorption of lithium ions by the anode becomes difficult. Instead, many lithium ions coat the surface of the anode, resulting in a phenomenon called lithium plating. This reduces the amount of lithium available to the power line, resulting in lower battery capacity.

Charging lithium batteries at temperatures below freezing, especially at high charging speeds, can compromise the mechanical stability of the battery and make it more susceptible to sudden failure. Freezing charging conditions cause loss of lithium ions in the graphite anode, causing plating and further reducing battery capacity while increasing resistance. If excessive plating occurs, the separator can be punctured and a dangerous short circuit can occur in the battery cell.

To solve these problems, it is important to avoid charging lithium batteries at freezing temperatures, especially at high charging speeds. Appropriate protection measures for low temperature charging can help preserve battery performance and prevent potential damage from excessive plating.

Although lithium batteries offer better cold weather performance compared to lead-acid batteries, it is still important to consider the effects of cold temperatures on their capacity and take the necessary precautions to ensure optimal performance and safety.

Can you charge a frozen battery?

It is important to avoid charging batteries at temperatures below freezing as this can cause significant and irreversible damage. Always ensure the battery has reached a safe temperature before initiating charging. To prevent cold weather from negatively affecting your batteries, consider using external heating pads and storing your battery bank in a heated chamber. These precautions can protect your batteries and maintain their optimal performance.

Power Queen low temperature protection and self-heating LiFePO4 lithium batteries help you get through the winter

Power Queen has upgraded the Winter series by integrating state-of-the-art features such as 12V 100Ah LiFePO4 batteries with integrated low temperature protection. There is also a notable self-heating series that offers options such as 12V 100Ah self-heating. These advancements aim to improve performance and reliability in cold weather conditions.

These 2 batteries are introduced in detail below.

Power Queen batteries with low temperature protection

Power Queen, 12.8V 100Ah low-temp LiFePO4 battery, has charging protection. at low temperatures

In cold weather conditions, it is important to have low temperature charging protection to protect the batteries from adverse charging effects. Charging batteries at low temperatures can result in reduced efficiency, reduced capacity and possible damage to the battery cells. To mitigate these risks and ensure optimal performance, implementing low temperature charging protections is essential.

These protection mechanisms work diligently by continuously monitoring the temperature during charging.

If the charging temperature falls below a certain threshold, which is typically around freezing point (32°F or 0°C), charging will automatically pause or stop. This preventive measure is important to avoid problems caused by low temperatures, such as lithium plating or mechanical instability, which could otherwise affect the performance and durability of the battery. Once the temperature rises to an acceptable level, charging can continue safely while maintaining the integrity of the battery.

This temperature range effectively covers cold conditions that can affect battery performance. The self-heating process is maintained until the battery temperature reaches 10℃ (50℉). Typically, it takes about 90 minutes for the battery temperature to rise from -10℃ to 10℃ (14℉ to 50℉), and about 150 minutes to go from -20℃ to 10℃ (-4℉ to 50℉).

With the built-in automatic self-heating function, these batteries ensure consistently optimal performance and reliability, even in extremely cold temperatures. The self-heating process effectively prevents possible problems related to low temperatures, allowing the batteries to work efficiently and serve as a reliable power source for your various applications.

Below you can see how the heating pad works.


These two series of batteries are specifically designed to address the challenges of charging LiFePO4 lithium batteries in cold weather. The main difference between the Low-Temperature series and the Self-Heating series is the type of temperature management.

In the Self-Heating series, the battery itself contains an automatic heating module that is integrated into the battery management system (BMS). This module ensures that the battery is heated independently during the charging process, which enables reliable operation even at low temperatures. The Low-Temperature Protection series, on the other hand, requires some user intervention, e.g. b placing the battery in a warm room to increase its temperature and restore proper charging function.
