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.
12V sealed lead acid batteries, or AGM, reach full charge at around 12.89 volts and reach complete discharge at about 12.23 volts. The table below shows a voltage chart of a 12V lead acid battery. 12V flooded lead acid batteries reach full charge at around 12.64 volts and reach complete discharge at about 12.07 volts.
The voltage range for lead-acid batteries varies depending on the type of battery. A flooded lead-acid battery has a different voltage range than a sealed lead-acid battery or a gel battery. An AGM battery has a different
The voltage range for lead-acid batteries varies depending on the type of battery. A flooded lead-acid battery has a different voltage range than a sealed lead-acid battery or a gel battery. An AGM battery has a different voltage range than a 2V lead-acid cell.

In the discharged state, both the positive and negative plates become lead(II) sulfate (PbSO 4), and the electrolyte loses much of its dissolved sulfuric acid and becomes primarily water. Negative plate reaction Pb(s) + HSO 4(aq) → PbSO 4(s) + H (aq) + 2e The release of two conduction electrons gives the lead electrode a negative charge. As electrons accumulate, they create an electric field which attracts hydrogen ions and repels s
Lead-acid batteries, like any other batteries, have a different voltage at different stages of charge. For example, a 12V lead acid battery has a 12.73V voltage at 100% charge and an 11.36V voltage at 0% charge. These specific battery
12V sealed lead acid batteries, or AGM, reach full charge at around 12.89 volts and reach complete discharge at about 12.23 volts. The table below shows a voltage chart of a 12V lead acid battery. 12V flooded lead acid
As the battery discharges, its voltage level decreases. Conversely, as the battery is charged, its voltage level increases. The following table shows the typical voltage range for a fully charged lead acid battery: It is
Here are lead acid battery voltage charts showing state of charge based on voltage for 6V, 12V and 24V batteries — as well as 2V lead acid cells. Lead acid battery voltage curves vary greatly based on variables like temperature, discharge rate and battery type (e.g. sealed, flooded).
$begingroup$ Summarizing, the main points are these two: 1) Once a 12V LA battery is down to 10-11V, the voltage will plummet rapidly. No real point in pushing it farther (and risking point 2), given that you only get a few % extra current out of it. 2) If a multi-cell battery is discharged too deeply you risk "polarity reversal" in the weakest cell.
A lead-acid battery in cold conditions may display a voltage drop, often falling below 12 volts. This reduced output can lead to decreased efficiency and capacity. Additionally, repeated exposure to extreme temperatures can damage the internal components of the battery.
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.. Let''s have a look at the 48V lead-acid battery state of charge and voltage decreases as well:
Overcharging with high charging voltages generates oxygen and hydrogen gas by electrolysis of water, which bubbles out and is lost. The design of some types of lead–acid battery (eg "flooded", but not VRLA (AGM or gel)) allows the electrolyte level to be inspected and topped up with pure water to replace any that has been lost this way.
Voltage drops beyond a certain threshold may indicate a discharged or faulty battery that needs recharging or replacement. The lead-acid battery voltage chart provides a
Another important indicator is the battery''s voltage. A fully charged lead-acid battery should have a voltage of around 12.8 volts. If the voltage drops below 12.4 volts, the battery needs to be recharged. Internal resistance is also an important factor to consider. A battery with high internal resistance will have difficulty delivering power
The following table shows the approximate voltage range for different states of charge for a 12-volt deep cycle battery: State of Charge Voltage Range; 100%: 12.7 – 12.8V: 75%: 12.4 – 12.6V: 50%: 12.0 – 12.2V: 25%: 11.6 – 11.8V: 0%: 10.5 – 10.8V: Voltage vs. Depth of Discharge (DoD) The voltage of a deep cycle battery is also related to its depth of discharge
Lead-acid batteries, like any other batteries, have a different voltage at different stages of charge. For example, a 12V lead acid battery has a 12.73V voltage at 100% charge and an 11.36V voltage at 0% charge. These specific battery voltage states of charge (SOC) are found in lead acid battery voltage charts.
But remember that each type of lead acid battery will have a different voltage range and that voltage charts only give a good general indication of the battery''s current charge. We''ll also cover how the battery voltage
The lowest safe voltage for a lead-acid battery is 11.8 volts. Going below this voltage can cause permanent damage to the battery and make it impossible to recharge. This can also cause the battery to lose its maximum capacity and make it unable to hold a charge for long periods.
According to the Battery University, a division of the Cadex Electronics, lead acid batteries exhibit a voltage range of about 2 volts per cell at 25°C. This standard voltage decreases at lower temperatures due to reduced reaction rates and increases at higher temperatures as the chemical reactions become more vigorous.

It''s a typical 12 volt lead-acid battery discharge characteristic and it shows the initial drop from about 13 volts to around 12 volts occuring in the first minute of a load being applied. Thereafter, the discharge rate doesn''t unduly affect the output voltage level until the battery gets
The voltage range for a lead acid battery can vary depending on the application in which it will be used. For example, the voltage range for a flooded lead acid battery should be between 11.95V and 12.7V. Meanwhile, the float voltage of a sealed 12V lead acid battery is usually 13.6 volts ± 0.2 volts.
A lower voltage reading on the Lead Acid Battery Voltage Chart generally suggests a lower state of charge in the battery. It indicates that the battery has less available energy and may require charging to maintain its optimal performance. Can the Lead Acid Battery Voltage Chart be used for all lead acid batteries?
Lead acid battery voltage curves vary greatly based on variables like temperature, discharge rate and battery type (e.g. sealed, flooded). The voltage to battery capacity chart in your battery manual should always take precedence over the generic, averaged ones listed below.
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?
To use a Lead Acid Battery Voltage Chart, locate the specific battery model you are using on the chart. Then, based on the voltage reading of your battery, you can determine its state of charge and make informed decisions about its usage or charging requirements.
A flooded lead-acid battery has a different voltage range than a sealed lead-acid battery or a gel battery. An AGM battery has a different voltage range than a 2V lead-acid cell.
