Yes, a power supply can charge a battery directly. The charging process will be slower than if you were to use a dedicated battery charger, but it will work. You’ll need to make sure that the polarity of the power supply is correct for the battery – check your documentation to be sure.

Does a battery need a DC power supply?

All that is needed to recharge battery cells is DC current. With DC current, electrons will flow back into the battery, establishing the electric potential, or voltage, that a battery was meant to have when it's fully charged. A DC Power Supply is needed that allows for adjustable voltage and current.

Can you use a switching power supply to charge a battery?

Yes, you can use a switching power supply to charge a battery. However, there are some things to keep in mind when doing this.
