14.5V 3.1A Switching AC DC Laptop Adapter 45W

• Due to the danger of lithium battery overcharge, the setting conditions of charge and discharge are more stringent than nickel-cadmium battery and nickel-hydrogen battery. A control circuit board is usually attached to a lithium battery to prevent overcharging. According to the characteristics of the lithium battery design, the first stage of charging is in the way of "constant current" charging, and when the battery is full, then charging in the way of "constant voltage" (about 4.1 ~ 4.2V) to make the battery reach the best state. Some seats on the market charge cut corners, the cell phone battery is identified as a nickel metal hydride battery, and in the way of "fixed current" charging, often easy to lead to lithium battery overcharge. A high quality protective circuit board will protect the lithium battery at this point to prevent the charger from continuing to charge. If you encounter a circuit board with poor design, it will not only fail to protect the battery and cause overcharging of the battery, but also cause deformation, leakage and explosion of the battery core due to overcharging.
