Does Low Temperature Affect The Battery?
Low temperature can significantly affect battery performance, especially for lithium batteries.
When the temperature drops, the chemical reactions inside the battery slow down. This means the battery cannot deliver power as efficiently as it does at normal temperatures. As a result, users may notice reduced capacity, lower voltage, slower charging, and weaker overall performance.
One of the most common effects of low temperature is capacity loss. A battery that normally provides full power at room temperature may only deliver part of its rated capacity in cold conditions. For example, in winter environments, batteries often appear to “run out” faster, even though they are not actually damaged. This happens because the battery’s internal resistance increases in cold weather, making it harder for energy to flow smoothly.
Low temperature also affects charging. Charging a battery in freezing conditions can be risky, particularly for lithium-ion batteries. At very low temperatures, lithium plating may occur during charging, which can permanently damage the battery and shorten its lifespan. For this reason, many lithium batteries include a Battery Management System (BMS) with low-temperature charging protection to prevent charging when the temperature is too low.
In addition, cold weather can reduce discharge efficiency. Equipment powered by batteries, such as marine devices, RV systems, solar storage, and electric vehicles, may experience weaker output or shorter runtime in winter. In severe cold, the battery may even fail to start certain applications if sufficient power cannot be released quickly.
However, low temperature does not always mean permanent battery damage. In many cases, once the battery returns to a suitable operating temperature, performance improves again. The main concern is improper charging in cold conditions and long-term exposure to extreme temperatures.
To reduce the impact of low temperature on batteries, users should store batteries in a moderate environment, avoid charging below the recommended temperature range, and choose batteries designed with low-temperature protection or self-heating functions when used in cold regions.
PLB Develops a Low-Temperature 26650 Battery Cell for Extreme Cold Applications
PLB has successfully developed a high-performance low-temperature 26650 battery cell designed to operate reliably in extremely cold environments.
