Is it dangerous to leave lithium batteries in the car?

Lithium batteries are dangerous if left in the car.

High or low temperature will cause the performance of lithium batteries to decrease. Especially under high temperature conditions, significant heat fluctuations will occur inside, causing explosions and other safety accidents. The temperature limit set for lithium batteries is generally 40 to 60 degrees, and explosion-proof valves are usually marked on the batteries.

High temperature resistant lithium batteries can withstand temperatures up to 800 degrees; general lithium batteries can withstand high temperatures of 200 degrees, 500 degrees and 800 degrees, etc., but under normal circumstances, daily use. You will never be exposed to such high temperatures in your life.

Purchasing considerations:

1. The capacityis it clearly marked? Batteries without clearly marked capacity (such as 1000 mAh or 1000 mAh) are most likely using lower quality batteries or recycled batteries. Many inexpensive batteries on the market are made from recycled batteries. Although they are cheap, their lifespan is short and their unstable quality can damage the phone.

2. Is there guaranteed standby time? Standby time is the duration of continuous use from the time the battery is installed in the phone until the next charge. Generally, batteries sold in the market cannot guarantee standby time to customers. This is because the battery quality is unstable. Many cheap batteries use poor quality battery cores, so the standby time is very short.

3. Whether to install a protective circuit boardof security. Without a protective circuit board, the lithium battery may deform, leak and explode. Faced with fierce competition for lower prices, each company searches for cheaper protective circuit boards or even omits this device, leaving the market flooded with lithium batteries that are at risk of exploding. Consumers cannot determine whether there is a protective circuit board from its appearance, so it is better to choose a reputable trader to purchase it.

Yes. According to information from Baidu Encyclopedia, lithium batteries are a kind of chemical energy source. When heated, squeezed, bumped, or otherwise abused, the separator fuses, resulting in direct contact between the positive and negative electrodes of the battery and an internal short circuit. . High temperature The electrode materials subjected to the action will undergo various exothermic reactions, causingfires and battery explosions.
