How to charge a lithium ion battery?

Besides, it is compatible with USB supplies and wall adapters. For best results in charging a 3.7 V Lithium-ion battery, apply a constant current of approximately 20 to 70 % of its capacity. You should do this until it reaches 4.2 V. Afterwards, charge the battery at a constant voltage until there is a 10% drop in the initial charge rate.

What is a lithium ion battery charger circuit?

Lithium-ion batteries’ popularity is rising owing to their significant advantages over lead-acid batteries. However, a Li-ion charger circuit is different from that of the latter. Next, let’s discuss them. A Li-Ion Battery You can charge a Li-Ion battery at a rate of 1C, equivalent to the battery’s Ah rating.

How does a lithium ion battery IC work?

Thus, connecting a discharged 3.7 V Lithium Ion Battery will prompt the IC’s pin 2 to detect the low voltage level and set it high. It initiates the charging process. When the battery archives its threshold full charge capacity, Pin 6 will change the output to low. Thus, this will limit further charging.

How to use LM317 IC for Li-ion battery charging?
