I am currently running a pilot where I have a 12V 5A regulated supply connected in parallel to the load (< 1Amp) and 12V 7AH sealed lead-acid battery While the setup actually works flawlessly, the flaw is that the battery is constantly being maintained at an undercharged state of 2-2.05V per cell which translates to approx 50% charge level.
The recommended charging voltage for a lead acid battery is between 2.25V and 2.30V per cell. For a 12V battery, this translates to 13.5V to 13.8V. How many amps should I use to charge a 12V lead acid battery? The number of amps you should use to charge a 12V lead acid battery depends on its capacity. As a general rule, you should use a

For 24V LiFePO4 batteries, the voltage range is slightly different: 80% charged is 27.2V-27.6V, 50% charged is 24.8V-25.2V, and so on.
If your lead-acid battery is not performing as expected, troubleshooting its voltage readings is a crucial step in identifying the
A Lead Acid battery at 11.8 volts without any load is at 0%. You never want to get there. Lead Acid should not be discharged to less than 50% especially a flooded battery if you want more than a hand full of uses before the battery is destroyed. This means that usable capacity of a Lead Acid battery: Is best-case 50% of rated capacity
A lead-acid battery that''s in perfect condition will be able to be recharged in maybe 10 hours, no matter how fast charger you have, since in the end the charging current is not limited by the charger but rather by the battery. A lead-acid battery that has been partially discharged for a period of 6 months can take as much as 30 hours to fully
The total voltage drop across the internal resistance is again given by Ohm''s law: $$ V_s = V_0/R_s $$ The net effect of this is that the total voltage you''ll see across the terminals of the battery will drop as you draw more current from the battery. At some point, the voltage will reach zero -- this is when you short the battery terminals together.

Being familiar with a lead acid battery voltage chart can help you to understand the state of your battery at a glance. What voltage should a fully charged lead acid battery be? A fully charged lead-acid battery should measure at about 12.6 volts.
The minimum open circuit voltage of a 12V flooded lead acid battery is around 12.1 volts, assuming 50% max depth of discharge. How much can you discharge a lead acid battery?
For example, a 12-volt lead acid battery has a nominal voltage of 12 volts. However, the actual voltage of a lead acid battery can vary depending on its state of charge, temperature, and other factors. The state of charge (SOC) of a lead acid battery refers to the amount of charge remaining in the battery.
The state of charge (SOC) of a lead acid battery refers to the amount of charge remaining in the battery. The SOC of a lead acid battery can be determined by measuring its voltage using a multimeter or other device. As the battery discharges, its voltage level decreases. Conversely, as the battery is charged, its voltage level increases.
Temperature affects lead acid battery voltage levels. The voltage level of a lead acid battery increases as the temperature decreases and vice versa. Therefore, you need to consider the temperature when measuring the voltage level of a lead acid battery. At what voltage level is a lead acid battery considered fully charged?
