Lead Acid Battery Voltage Chart: The Voltage Level Differences

The float voltage of a flooded 12V lead-acid battery is usually 13.5 volts. The 24V lead-acid battery state of charge voltage ranges from 25.46V (100% capacity) to 22.72V (0% capacity). The 48V lead-acid battery state of charge voltage ranges from 50.92 (100% capacity) to 45.44V (0% capacity).

how to charge a battery using a SMPS???

1,325. You cannot charge the lead-acid battery well, using 12V. For the battery to be fully charged, you need to bring it up to "float" voltage which is about at least 13.7V. There are various algorithms of charging that employ constant current, or constant voltage, or both, and then trickle-charge/floating of fully charged battery.
