The circuit is set up for a single-cell Li-Ion battery, where the lockout voltage—the voltage when the protection circuit disconnects the load from the battery—is 3.0V. This voltage, set by the ratio of R1 and R2, is sensed at node A. When the battery voltage drops below 3.0V, node A falls below the threshold at node B, which is defined as:

All About Low-Voltage Disconnect

If a battery has a voltage over 11.5V, charge it with a lithium charger. If the battery''s voltage is below 11.5V, connect it to a car, just like you would jump a car battery, and let it idle for 15 minutes.
