Lithium battery charger is a charger specially used to charge lithium ion batteries.
Lithium-ion batteries have higher requirements for chargers and require protection circuits. Therefore, lithium-ion battery chargers usually have high control precision and can charge lithium-ion batteries with constant current and voltage.
Features:
Ideal control circuit for single-cell or 8.4V dual-cell Li-ion or Li-polymer battery chargers;
Voltage accuracy higher than 1[%];
During the pre-charging process, the user can change the pre-charging current;
Constant current charging, adjustable charging current;
Constant voltage charging process;
Automatic recharging process;
Temperature monitoring during charging;
LED charging status indication;
Detection of abnormal battery status;
When the power supply voltage is low, it is in a low-power sleep mode, and the battery leakage current is extremely small;
Few peripheral components;
Precautions
1. The working selection of the charger should be consistent with the battery being charged. If the charger is working in the state of lithium battery to charge the nickel-metal hydride or nickel-cadmium battery, the battery is not fully charged, which will greatly reduce the working time. If the charger works in the state of a nickel battery to charge a lithium ion battery, the lithium battery will be overcharged, which will seriously affect the battery life.
2. To understand what the battery is when the charger is fully charged and lit
