What are the 3 Stages of Battery Charging? The three stages of battery charging are bulk, absorption, float, and equalization. Bulk stage. In the bulk stage, the charger supplies the maximum charge current that the battery can accept. The voltage is held at a constant level until the battery reaches approximately 80% of full charge.
For lead-acid batteries, the initial bulk charging stage delivers the maximum allowable current into the solar battery to bring it up to a state of charge of approximately 80 to 90%. During bulk charging for solar, the battery''s voltage increases to about 14.5 volts for a nominal 12-volt battery. Absorption Charging
