Every battery has a cut-off point; this point is a voltage at which the battery has been completely discharged. Manufacturers sometimes specify cut-off voltages for various discharge rates. The cut-off voltage is very sensitive to discharge rates. If the battery has a high discharge rate, it will have a lower cut-off voltage and vice versa.
Power source feeds power to a charger circuit such as the TP4056 module which charges a lithium cell, say an 18650. At some point after the charging phase, a DC booster steps up the voltage to a desired voltage, which is then connected to the load.

Battery voltage must not exceed 4.2V: When charging the Li-ion battery, there is a strict rule. That does not let the battery voltage exceed 4.2V. We have a 12V power supply: When the battery is charging, its voltage level rises to the level of the power supply. So, the battery will deteriorate or be damaged.
At this low current, the time the Li-Ion battery takes to reach the end-of-discharge voltage is significantly extended. For other protection circuitry that typically requires higher current, the rate of discharge is faster, allowing the battery voltage to drop below the safe limit in a shorter time.
