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.
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.
If you need float charge for operational readiness, lower the charge voltage to about 2.25V/cell. 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.
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.
The terminal voltage of the Lead-Acid battery should be within a certain range such as 12 to 13Volt. In the event that the battery voltage lessens beneath 10 volts for a long period, the battery won’t accept any charging current. Thus, if the terminal voltage surpasses over 14 volts, the battery will be devastated.
For lead acid charging should be no big deal - but if the supply has sense inputs, then those will in turn need to be fused. If you are using flooded lead-acid, hook it up with 14.4v supply with even higher current. (Your car easily charges at 25 Amp). So, go ahead with 5 - 10Amps if your power supply can output.
