After the current reaches the cutoff point (3-5% of the C rate of the cell) the voltage should be lowered to 13.5V to 13.8V (the "float voltage"). Diagram from the excellent Battery University. Read there article on Lead Acid charging for excellent detailed information .
Then, the voltage is limited to the peak voltage until the current drops (to 3-5% of the C rate for lead acid batteries). Standard "12V" Lead-acid batteries are six cells; the peak charge voltage is between 13.8 and 14.7V (at 25C, this value is temperature dependent); however prolonged time at this voltage will cause damage.
Overcharging Lead Acid batteries will damage them and can cause Hydrogen and Oxygen gas to form, leading to an explosion risk. You should never, under any circumstances, provide a voltage higher than the rated peak voltage! A charging curve limits the current into the battery until the voltage rises to the peak battery voltage.
If a lead acid battery is not charged and discharged below its recommended voltage, it can cause permanent damage to the battery. This can also reduce the battery’s capacity and lifespan. To ensure its long-term health and performance, avoid discharging the battery below its recommended voltage level.
