Li-ion battery charger with overvoltage protection and temperature protection, the maximum charge time limit to provide secondary protection for Li-ion batteries, and Li-ion battery charger float charging mode can make the battery capacity to the maximum. The Li-ion battery charger can automatically detect the charging power source and automatically shut off when there is no power source to reduce battery leakage. When the charging power and the battery are in the normal operating temperature range, inserting the battery will start a charging process; the end of charging conditions is the average pulse charging current reaches 1% of the fast charging current, or the time exceeds the on-chip preset charging time.

　　The li-ion battery charger is a charger specifically designed to charge Li-ion batteries. Lithium-ion batteries have high requirements for chargers and need protection circuits, so lithium-ion battery chargers usually have high control precision and can charge lithium-ion batteries with constant current and constant voltage.

　　Precautions for lithium battery chargers

1. Should make the charger work to choose the same as the battery being charged. If the charger works in the lithium battery state and goes to allow NiMH or NiCd batteries, the battery is not charged, which will greatly reduce the working time. If the charger works in the state of nickel batteries and charges lithium-ion batteries, lithium batteries are overcharged, which will seriously affect the life of the battery. 2. To understand the charger used to fill the light when the battery has really been full. Some chargers see the full indicator light can be removed from the lithium battery, and some chargers see the indicator light is fully lit before the battery can be removed.

　　Lithium battery charger charging process instructions

　　When the power is not connected, the LED on the circuit board does not light up.

　　Power connected to the circuit board, the green LED continues to light up. At this time, the board is waiting for the lithium battery.

　　After the lithium battery is put in, it starts charging, and the LED turns orange.

　　When the lithium battery reaches full condition, it stops charging, and the LED turns orange.

　　After the lithium battery is filled, the battery is removed, the LED turns green, and re-install the lithium battery charging.

　　During the charging process, the charging percentage is displayed.

　　LEDs.

　　Continuous green: waiting for the battery to be placed

　　Continuous yellow: charging in progress

　　Continuous orange: the battery is fully charged or has been charged for 6 hours

　　Flashing orange: warning message (output short circuit, reversed positive and negative, abnormal temperature)

　　Li-ion battery charger in our lives is more common, but they are also used more. In the use of the process, we should pay attention to its maintenance so as to make its service life longer.
