Charging voltage: The final charging voltage, when fully charged, is related to the harmful electrode material of the battery. Coke is 4.1V, while graphite is 4.2V, which are generally called 4.1V lithium-ion batteries and 4.2V lithium-ion batteries. When charging, it should be noted that 4.1V cells cannot be accused of 4.2V chargers. Otherwise, there will be a danger of overcharging (the charger IC used by 4.1V and 4.2V chargers is different). Lithium-ion batteries have high requirements for charging, and they require sophisticated charging circuits to ensure the safety of charging. The tolerance of the termination charge voltage accuracy is ±1% of the rated value (for example, for a 4.2V lithium-ion battery, the understanding is ±0.042V). Overvoltage charging will cause permanent damage to the lithium-ion battery.
