A fully charged lead-acid battery should measure at about 12. This is the voltage when the battery is at its fullest and able to provide the maximum amount of energy.
The 24V lead-acid battery state of charge voltage ranges from 25.46V (100% capacity) to 22.72V (0% capacity). 48V Lead-Acid Battery Voltage Chart (4th Chart). The 48V lead-acid battery state of charge voltage ranges from 50.92 (100% capacity) to 45.44V (0% capacity). Lead acid battery is comprised of lead oxide (PbO2) cathode and lead (Pb) anode.
The highest voltage 48V lead battery can achieve is 50.92V at 100% charge. The lowest voltage for a 48V lead battery is 45.44V at 0% charge; this is more than a 5V difference between a full and empty lead-acid battery. With these 4 voltage charts, you should now have full insight into the lead-acid battery state of charge at different voltages.
For instance, a 12V sealed lead acid battery has a voltage of 12.89V at 100% charge, while 11.63V indicates it is at 0% charge. The good news is that you can refer to a lead acid battery voltage chart to find the specific battery voltage (6V, 12V, 24V, 48V, etc.) corresponding to the state of charge (SOC).
We see the same lead-acid discharge curve for 24V lead-acid batteries as well; it has an actual voltage of 24V at 43% capacity. The 24V lead-acid battery voltage ranges from 25.46V at 100% charge to 22.72V at 0% charge; this is a 3.74V difference between a full and empty 24V battery.
A lead acid battery is considered fully charged when its voltage level reaches 12.7V for a 12V battery. However, this voltage level may vary depending on the battery's manufacturer, type, and temperature. What are the voltage indicators for different charge levels in a lead acid battery?
As a lead acid battery discharges, the voltage decreases linearly. For example, a 12V battery may provide 12.6V when fully charged. After discharging halfway, the voltage will drop to around 12.3V. The rate of discharge impacts the voltage. Faster discharge rates result in lower voltages for a given state of charge.
The C-Rate represents the ratio of the charge or discharge current to the rated capacity of the battery. Think of the battery C rating as the rate at which a battery .

A typical lead–acid battery contains a mixture with varying concentrations of water and acid. Sulfuric acid has a higher density than water, which causes the acid formed at the plates during charging to flow downward and collect at the bottom of the battery.
According to a 2003 report entitled "Getting the Lead Out", by Environmental Defense and the Ecology Center of Ann Arbor, Michigan, the batteries of vehicles on the road contained an estimated 2,600,000 metric tons (2,600,000 long tons; 2,900,000 short tons) of lead. Some lead compounds are extremely toxic.
This comes to 167 watt-hours per kilogram of reactants, but in practice, a lead–acid cell gives only 30–40 watt-hours per kilogram of battery, due to the mass of the water and other constituent parts. In the fully-charged state, the negative plate consists of lead, and the positive plate is lead dioxide.

Whilst lithium-ion battery packs offer longer working lives, lead acid are the more cost effective and to a wider degree more environmentally friendly.
If you need a battery backup system, both lead acid and lithium-ion batteries can be effective options. However, it's usually the right decision to install a lithium-ion battery given the many advantages of the technology - longer lifetime, higher efficiencies, and higher energy density.
Lithium has several advantages over other types of batteries, including lead-acid. With a lifespan of 10 years or more, a lithium battery lasts at least twice as long as a standard lead-acid battery. It also doesn't need maintenance like lead-acid batteries, which require an equalizing charge and monitoring to ensure the batteries don't dry out.
Electrolyte: Dilute sulfuric acid (H2SO4). While lithium batteries are more energy-dense and efficient, lead acid batteries have been in use for over a century and are still widely used in various applications. II. Energy Density
Lead acid batteries can pack around 50-90Wh/L in a battery set compared to 125-600Wh/L for lithium-ion. Comparing the type of battery technologies can typically show lead acid sets requiring a volume (footprint and height) up to 10 times greater than a comparable lithium-ion backup solution.
Until this problem is solved, and lead acid batteries are on a par for first purchase and recycling, lead acid remains the most sustainable technology. Today, lead acid batteries remain the first choice for uninterruptible and backup power systems.
Lead acid batteries function through a chemical reaction between the lead plates and the sulfuric acid electrolyte. When the battery discharges, the lead plates react with the electrolyte, producing lead sulfate and releasing electrical energy. The process is reversed during charging, converting lead sulfate into lead and lead dioxide.
