1, lithium-battery charging: based on the structure characteristics of lithium-ion batteries, the maximum charging voltage should be 4.2V, not overcharge, or positive electrode of lithium ion took too much, and discard the battery. The higher charge and discharge requirements, constant current, constant voltage charger for use to recharge. Usually constant current charge to 4.2V/after transfer to constant voltage charging, when the constant voltage charge current below 100mA or less, should stop charging.
2, lithium-ion battery discharge: partly due to the internal structure of lithium-ion batteries, discharge lithium-ion cannot be moved to the cathode, the part must retain lithium ions at the cathode, to ensure that when the next charge lithium-ion can easily embed channel. Otherwise, the battery life will be shortened. In order to ensure that the discharge in the graphite layer after that leave some lithium-ion, it is necessary to strictly restrict the discharge end minimum voltage, which means that lithium-ion batteries cannot discharge. Final discharge voltage for the 3.0V/section, must not be less than 2.5V/. Battery discharge time and battery capacity, the current size. Battery discharge time (hours) = battery capacity/discharging current. Lithium-ion battery discharge current (mA) should not exceed 3 times times the battery capacity. (For example, 1000mAH battery, the discharge current should be strictly controlled in the 3A) or you will damage the battery.
