How to Calculate the time of Charging and Discharging of battery?
You also need to keep in mind that a battery is not supposed to be "fully" discharged. Typically, a battery is considered "discharged" when it looses 1/3 of its capacity, therefore it only needs 1/3 of its capacity to be fully charged (range of operation). With these constraints and the above values, one gets only one answer, t = 33Ah/10A = 3.3hr

Complete Guide on How to Charge a Lead Acid Battery
The battery is fully charged once the current stabilizes at a low level for a few hours. There are two criteria for determining when a battery is fully charged: (1) the final current level and (2) the peak charging voltage while this current flows.

When the battery is fully charged the electrolyte has the maximum amount of sulfuric acid so the specific gravity is highest. As the battery discharges the acid is converted into lead sulfate plus water so the specific gravity drops. The manufacturer should provide specific gravity numbers for full charge and discharge.
