Before connecting the battery, calculate the charge voltage according to the number of cells in series, and then set the desired voltage and current limit. To charge a 12-volt lead acid battery (six cells) to a voltage limit of 2.40V, set the voltage to 14.40V (6 x 2.40). Select the charge current according to battery size.
Below is a chart I found of the changing resistance of a lead acid battery compared to state of charge, however, the charge acceptance is higher when it is discharged compared to when it is charged. How does this happen with a higher resistance that gradually gets lower? I'm also assuming a constant charging voltage from an alternator.
It is important to check the battery’s documentation for the recommended charging current limits and to use a charger that is within those limits. What is the ideal float voltage for a 12V sealed lead-acid battery? The ideal float voltage for a 12V sealed lead-acid battery is between 13.5 volts and 13.8 volts.
Deeply discharging a lead acid battery damages it so doing that for the sake of doing that doesn't sound like a good idea. And if you have some reasonable usecase for that then you'd better explain so that answers can address your actual problem. A discharged lead-acid battery can hardly be considered safe.
The charging process of a lead-acid battery involves applying a DC voltage to the battery terminals, which causes the battery to charge. The discharging process involves using the battery to power a device, which causes the battery to discharge.
The time it takes to discharge a sealed lead-acid battery can vary depending on the load and the battery’s capacity. It is important to monitor the battery’s voltage during the discharge process to ensure that it does not drop below the recommended threshold.
