Before connecting the battery, calculate the charge voltage according to the number of cells in series, and then set the desired voltage and current limit. To charge a 12-volt lead acid battery (six cells) to a voltage limit of 2.40V, set the voltage to 14.40V (6 x 2.40). Select the charge current according to battery size.
When charging a lead-acid battery with a bench power supply, it is important to set the voltage and current limit correctly. The voltage should be set to 2.4V per cell, and the current should be set between 10% and 30% of the battery’s rated capacity. It is also important to monitor the battery’s temperature during charging to avoid overheating.
You can also use the power supply to equalize a lead acid battery by setting the charge voltage 10 percent higher than recommended. The time in overcharge is critical and must be carefully observed. (See BU-404: What is Equalizing Charge) A power supply can also reverse sulfation.
Test show that a heathy lead acid battery can be charged at up to 1.5C as long as the current is moderated towards a full charge when the battery reaches about 2.3V/cell (14.0V with 6 cells). Charge acceptance is highest when SoC is low and diminishes as the battery fills.
To charge a sealed lead acid battery, a DC voltage between 2.30 volts per cell (float) and 2.45 volts per cell (fast) is applied to the terminals of the battery. Depending on the state of charge (SoC), the cell may temporarily be lower after discharge than the applied voltage. After some time, however, it should level off.
To charge a 12V battery with a power supply, you need to adjust the voltage and current settings of the power supply. Most power supplies have adjustable voltage settings, which is necessary when charging a battery. You need to ensure that the voltage setting matches the voltage of the battery you want to charge.
