As a general rule, you should use a charging current of 10% of the battery’s capacity. For example, a 100Ah battery should be charged with a current of 10A. In conclusion, the recommended charging current for a new lead acid battery depends on the battery capacity and the charging method used.
Test show that a heathy lead acid battery can be charged at up to 1.5C as long as the current is moderated towards a full charge when the battery reaches about 2.3V/cell (14.0V with 6 cells). Charge acceptance is highest when SoC is low and diminishes as the battery fills.
Lead acid charging uses a voltage-based algorithm that is similar to lithium-ion. The charge time of a sealed lead acid battery is 12–16 hours, up to 36–48 hours for large stationary batteries.
For example: In a 12V 45Ah Sealed Lead Acid Battery, the capacity is 45 Ah. So, the charging current should be no more than 11.25 Amps (to prevent thermal runaway and battery expiration). Importantly, if you have other equipment connected to the battery during chargning, it also needs to be powered, so you need to add that to your calculations.
This mode works well for installations that do not draw a load when on standby. Lead acid batteries must always be stored in a charged state. A topping charge should be applied every 6 months to prevent the voltage from dropping below 2.05V/cell and causing the battery to sulfate. With AGM, these requirements can be relaxed.
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). For AGM sealed lead acid batteries, the ideal charging current is 25% of the battery capacity indicated by Ah (Ampere Hour).

Car Battery Voltage Chart
A fully charged car battery should measure 12.6 volts or above when the engine is off. The chart helps determine if the battery has enough power to start the car and keep it running. For instance, if the voltage falls between 10.5 and 11.0 volts, the battery is discharged and may have a bad cell. Car battery voltage typically ranges from 12.6 to 14.4 volts, with the …

Guide: Maximum Charging Current & Voltage For 12v Battery
As a rule of thumb, the minimum amps required to charge a 12v battery is 10% of its full capacity but the ideal charging current should be between 20-25% of the battery''s capacity. For example. if you have a 12v 100Ah battery then you''ll need a minimum of 10 amps and a maximum of 20-25 amps to recharge your battery.
