What to pay attention to when charging polymer battery fast

The fast charge principle of polymer fast charge battery. The basic principle of fast charging mode is Pu003dUI (poweru003dvoltage*current). To increase the speed of fast charging, the power must be increased, and the voltage and current are proportional. Precautions for polymer fast charge battery during fast charge. 1. To prevent excessive discharge, try not to use the mobile phone below 20% of the battery power, especially do not use the mobile phone below 5% of the battery power, which will cause irreversible damage to the battery. 2. Prevent overcharge. Overdischarge and overcharge will cause great damage to the lithium-ion battery of the mobile phone. However, the current smart phone generally has circuit protection, and the battery will no longer be charged after it is fully charged. 3. Prevent use at high or very low temperatures. Charging at high and low temperatures will cause great damage to the lithium-ion battery of the mobile phone. High temperature may cause the battery to explode, while low temperature will also have a great impact on battery life. 4. Prevent your mobile phone battery from being in a non-powered state for a long time. If the battery is in a non-powered state for a long time, it is very likely that your mobile phone will no longer be able to turn on. 5. The ideal state of the lithium-ion battery is when the battery is 40% left. At this time, the voltage of the battery will not be too high or too low. The higher the battery, the faster the decline. A 100% battery will be stored for one month. If 50% of the battery is left for one month, the capacity of the former will decline more; do not maintain the battery's power at 100% for a long time, as this will affect the battery life to a certain extent.
