Belongs to. According to Xinhuanet's query: External batteries are flammable and explosive objects because they are lithium polymer battery storage equipment, equivalent to large capacity backup batteries for lithium battery equipment, and are used with telephones. laptops, iPads, laptops, cameras, camcorders, etc. Like the lithium batteries contained in the equipment, they can easily cause spontaneous combustion when exposed to heat in a high altitude environment.
Batteries are unsafe and carry risks. According to data, although the probability of lithium batteries exploding is very low, the risk of spontaneous combustion of lithium batteries is relatively high.
Ordinary lithium battery products will undergo rigorous testing before leaving the factoryto avoid external factors causing hidden dangers to products. Test items include environmental adaptability to heat resistance, vibration resistance, collision resistance and free fall resistance; circuit; storage performance, etc.
Conventional lithium battery brands place the fully charged battery in a high temperature test chamber during testing, and heat it at a rate of 3-7 degrees Celsius/minute when the temperature reaches 130 degrees . Celsius, timing starts and keeps Even if the temperature stays in the range of about 130 degrees Celsius for one hour, it can still prevent leakage, fire or explosion.
In order to avoid internal short circuits in the product, high-quality lithium batteries will design an intelligent battery management system to greatly improve the stability and reliability.has pressure resistance of lithium batteries and protect lithium batteries from various abnormal conditions. , which can realize intelligent charging and discharging, adjustable charging current and other advantages.
There are 8 major precautions when using lithium batteries. You must remember: Choose a charger suitable for the lithium battery; Do not charge below 0℃ or above 45℃; It is strictly forbidden to connect the positive; and negative batteries in reverse; Non-professionals. Do not disassemble the battery yourself.
Do not charge the battery indoors; do not store it mixed with flammable and explosive materials; when the battery is soaked in water, dropped or knocked, please check it if it is not used for more than $2,000,000; 7 days, take out the battery and do not use it for a long time, charge it once a month.
