If the battery voltage is lower than VBATT_TC (trickle charge pre-charge voltage threshold) (2V/cell), the IC will charge the battery with a trickle charge current of 100mA (adjustable). The trickle charge stage is usually only used when the battery voltage is below a very low level (about 2.1V).
What are 3 Stages of Battery Charging? The three stages of battery charging are known as the bulk stage, the absorption stage, and the float stage. Each stage has a different purpose and helps to keep your battery working at its best. During the bulk stage, the charger supplies a high current to the battery in order to quickly charge it up.
