A battery is an important part of a power system. It stores electrical energy and releases it when needed. Most batteries in the world run on lead acid, which has many variations in voltage and capacity. Typically marked as V battery and ah battery. Knowing the lead acid battery voltage chart will let you make informed decisions about your batteries and system. In this blog, we discuss the history of lead acid batteries, how they work, and their voltage charts. Let’s get into it!
What is a lead acid battery?
A lead acid battery is a type of battery that uses lead and lead oxide as the active material. Lead acid batteries are used in automobiles, trucks, bicycles, and other portable applications. It can be classified as AGM, Gel and sealed lead acid batteries.
The six-volt lead acid battery is the most common type of lead acid battery. A 12-volt lead acid battery has twice the capacity of a 6-volt lead acid battery. A 24-volt battery has four times the capacity of a 6-volt battery. The 48-volt lead acid battery has eight times the capacity of a 6-volt battery. The 60-volt battery has twelve times the capacity of a 6-volt battery. The 72-volt battery has sixteen times the capacity of a 6-volt battery.
After a long period of operation, the consistency of the battery cells will decrease, resulting in a lack of overall efficiency. Deploying an Lead Acid Battery Balancer can effectively solve this problem, thus improving battery performance and extending battery life.
A lead acid battery’s lifespan depends on its charge and discharge rate, temperature, and other factors specific to that particular type of battery. To ensure optimal performance, it’s important to follow the manufacturer’s directions for charging, discharging, and storage of batteries. see our 15 Steps to extend lead acid battery life.
Lead acid battery voltage chart
A battery voltage chart is a useful reference for estimating the charge capacity of a lead acid battery. This chart provides battery voltage information for lead acid batteries of various voltages, such as 6V, 12V, 24V, 48V, 60V, 72V. The chart provides a reference of how much voltage is needed to charge a battery and the full charged voltages. It also helps identify which lead acid battery is suitable for a specific application.
It can be printed out and used as a battery inventory sheet. Likewise, it can be used to troubleshoot battery problems by providing reference points for different voltages. The chart can be used to estimate the charge capacity of a lead acid battery by using the relationship between voltage and capacity. A higher voltage indicates greater capacity.
How to read a lead acid battery voltage chart
The lead acid battery voltage chart is a helpful tool for identifying the condition of a lead acid battery. This chart lists voltages of battery cells of various capacities in order to help you troubleshoot issues with lead acid batteries. The voltage of a battery cell is determined by the amount of current it can handle and is a good indicator of its state of charge. When reading the voltage on the chart, it’s important to understand what each mark represents. For example, 12 V on the scale means that one of the battery cells has a voltage of 12 volts.
-6V indicates that one of the battery cells has a voltage of -6 volts. In general, as the charge state of a battery cell decreases, its voltage decreases. So, reading a lead acid battery voltage chart will help you identify problems with lead acid batteries and estimate how much power they can generate.

12V Lead Acid Battery Voltage Charts
A battery’s voltage is measured in volts. A lead-acid battery’s voltage is the electrical potential of the battery and is represented by its voltage ‘V’. A typical 12-V lead-acid battery has a voltage of 12V. When a battery discharges, its voltage decreases. Conversely, when a battery charges, its voltage increases.
A lead-acid battery can be connected to a solar panel or other source of DC power to charge it. When the battery is fully charged, its voltage will equal the voltage of the power source. This is called being fully charged or fully charged. Batteries also have different voltages for different states of charge. These are referred to as ‘full charge,’ ‘half charge,’ and ’empty’ state.
A 12V battery has 6 single cell lead-acid batteries connected in series, the nominal voltage of a single cell is 2.0V, the maximum voltage is only 2.4V. 12V lead-acid batteries are fully charged at 14.4V by default.
For 12V battery, when the open circuit voltage is lower than 12.4V, the power is about 60% remaining, it can be used when the voltage is not less than 10.5V.
If the open circuit voltage is lower than 11.5V, it will be over discharged and cause damage to the battery.
The normal voltage of 12v battery is about 12.8V, plus or minus 0.3V, if the voltage is lower than 12.5V, it needs to be charged in time.
It is a sign of weakened battery performance if the voltage after a full charge is only 12V or even less than 12V.
12V lead battery full charge voltage is 14.4V, After a long time of use may not be so high, but also not too low.

24V Lead Acid Battery Voltage Charts
The 24V battery is connected in series with two 12V batteries. The maximum charge voltage of a 12V battery is about 15V. After an hour of rest, the voltage drops to about 12.7V.
At full charge, the 24V Lead Acid battery voltage will be approximately 30V, and after an hour’s rest, the voltage will drop to approximately 25.4 volts.
A 24 volt battery should be charged at 24 volts to 28 volts.
The end-of-discharge voltage of a 24-volt battery is 21 V, and anything less than this value means that the battery needs to be recharged.
24V Lead Acid Battery Voltage Table
48V Lead Acid Battery Voltage Chart
The 48V lead acid battery is the most popular type of lead acid battery due to its longer lifespan and higher capacity compared to the 12V, 24V and other lead acid batteries. The 48V lead acid battery is used in a wide variety of applications, such as vehicles, power tools, and medical equipment.
As the 48V battery is made up of 4 12V batteries in series, the minimum discharge voltage of each battery is 10.50V, so the minimum discharge voltage of 4 batteries in series is 10.50×4=42V or so.
For a typical 48V lead-acid battery, under normal circumstances, the no-load voltage of the battery is approximately 53 volts, the full charge cutoff voltage is 56 volts, and the discharge cutoff voltage is approximately 40 volts. The normal voltage range is between 46 and 54 volts, The battery will not be able to provide power if the voltage is below 46V.
48V lead battery full charge voltage is 56V.
After charging, unplug the charger. The voltage will be in a stable state after half an hour, and the voltage is normal at 52.7 – 54.7V after the battery is full.
If the measured voltage is less than 52V after charging, the battery performance is not good.

60V Lead Acid Battery Voltage Chart
60V lead battery is considered 5 groups of 12V battery in series.
60V lead-acid battery, the under voltage is 54V, the full charge voltage is 72V.
The voltage of 60V battery is 72V after full charge, because the terminal voltage (terminal voltage) inside the battery is 1.2 times of the rated voltage. If it is a 60V battery, the full charge voltage after charging is actually the rated voltage multiplied by 1.2 times is equal to 72V.
Therefore, 60V lead battery full charge voltage is 72V.
When the battery is fully charged, the voltage inside will drop to a stable range of 65V~72V as the time of sitting gets longer.
A 60V battery, the voltage is lower than 52.5V, should be charged, further use will cause damage to the battery.

72V Lead Acid Battery Voltage Chart
72V Lead Acid battery is best suited for applications where high energy outputs are required, such as solar energy systems or electric vehicles. This battery has a higher capacity than the conventional batteries, and it can be charged and discharged more times without weakening its capacity.
If lead-acid type, 72V battery should be 6 12V lead-acid batteries in series.
The full charging voltage of a single lead-acid battery is usually 13.7~13.8V, 72V is composed of 6 batteries in series, and the charging voltage is 82.2~83.8V.
When a 72V battery is fully charged, the voltage can reach about 83V. The voltage of the battery is stable at about 79V after unplugging the charger for half an hour.
After using the battery for about a year, it will reach 78V when fully charged.
The under voltage value of the 72V battery is 65V, if the voltage of the battery is lower than this value, the battery will stop working and will need to be recharged.
