Is It Dangerous to Leave Lithium Batteries in the Car During Summer?
2 Answers
Leaving lithium batteries in the car during summer is extremely dangerous, as the batteries can explode when exposed to high temperatures. Here is some relevant information about power batteries: 1. High-temperature resistance: In high-temperature tests, ordinary lithium batteries can withstand temperatures of 200 degrees, 500 degrees, and even 800 degrees. However, such extreme temperatures are rarely encountered in daily life. 2. Temperature limits: Under high-temperature conditions, significant heat fluctuations can occur inside the battery, leading to safety hazards such as explosions. The temperature limit for lithium batteries is generally set between 40-60 degrees. Most batteries are labeled with explosion-proof valves, while high-temperature-resistant lithium batteries can withstand up to 800 degrees.
I remember one summer when I left my newly bought phone on the back seat. When I returned, the car was like a steamer—the phone was so hot I couldn’t even hold it, and the battery had swollen, almost cracking. Since then, I’ve never dared to leave any lithium battery in the car. Summer temperatures can easily soar above 50°C, accelerating the chemical reactions inside lithium batteries, which can lead to overheating, swelling, or even fire. This is no small matter—items like phones and power banks are especially dangerous if left exposed to direct sunlight in the car. It’s best to carry them with you or store them in a shaded spot. I’ve also developed a habit: checking my pockets before leaving the car to avoid forgetting any electronics, sparing myself the anxiety that could ruin my trip.
