In conclusion, the recommended charging current for a new lead acid battery depends on the battery capacity and the charging method used. It is generally recommended to charge a sealed lead acid battery using a constant voltage-current limited charging method with a DC voltage between 2.30 volts per cell (float) and 2.45 volts per cell (fast).
