If the cell phone battery has been soaked in water, it is recommended not to use it.
Mobile phone batteries are dangerous goods. In real life, many casualty incidents have been caused by batteries burning and exploding, so be careful. If only the battery contacts are wet, clean it with alcohol and it will still be usable. If it has been completely submerged in water, be careful in this case, as the protection circuit inside the battery may be short-circuited and the explosion-proof function will not be achieved. It's better to buy a new one.
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.
Battery productsOrdinary lithium will undergo rigorous testing before leaving the factory to avoid external factors causing hidden dangers to the 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 circuit in the product, high quality lithium batteries will design a system ofintelligent battery management to significantly improve the stability and 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, remove the battery and do not use itz not for a long time, charge it once a month.
