Source measure units, devices that function both as a power supply and a multimeter/electronic load, are ideal for these types of tests. In this video, applications engineer Barry Bolling uses a GS610 source measure unit to perform a charge-discharge test on a lead acid battery to show how to test lead acid battery capacity.
The formula for determining the capacity of a lead-acid battery is: Capacity (Ah) = (RC / 2) + 16 For example, if a lead-acid battery has a reserve capacity of 120 minutes, its capacity would be:
Capacity is the leading health indicator of a battery, but estimating it on the fly is complex. The traditional charge/discharge/charge cycle is still the most dependable method to measure battery capacity. While portable batteries can be cycled relatively quickly, a full cycle on large lead acid batteries is not practical for capacity measurement.

Lead–acid batteries designed for starting automotive engines are not designed for deep discharge. They have a large number of thin plates designed for maximum surface area, and therefore maximum current output, which can easily be damaged by deep discharge. Repeated deep discharges will result in capacity loss and ultimately in premature failure, as the electrodes disintegrate

The fundamental elements of the lead–acid battery were set in place over 150 years ago 1859, Gaston Planté was the first to report that a useful discharge current could be drawn from a pair of lead plates that had been immersed in sulfuric acid and subjected to a charging current, see Figure 13.1.Later, Camille Fauré proposed the concept of the pasted plate.
We discuss lead-acid battery capacity specifically in this post, although what follows generally applies to all electrochemical cells. A Conceptual Model for Lead Acid Battery Capacity. Battery capacity refers to what each
So, how much battery capacity does your application need? It depends on your specific requirements and usage patterns. Different battery types, such as lithium battery and lead-acid batteries, have varying capacities. Generally, lithium batteries possess the greatest capacity, which is another reason that we at Enduro Power Batteries have
N. Maleschitz, in Lead-Acid Batteries for Future Automobiles, 2017. 11.2 Fundamental theoretical considerations about high-rate operation. From a theoretical perspective, the lead–acid battery system can provide energy of 83.472 Ah kg −1 comprised of 4.46 g PbO 2, 3.86 g Pb and 3.66 g of H 2 SO 4 per Ah.
Omni''s battery size calculator (or remaining battery capacity calculator) explains in detail how to check the battery capacity for both lithium-ion and lead-acid batteries.

The lead–acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Plant é. It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead–acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents. These features, along with their low cost, make them

12V sealed lead acid batteries are fully charged at around 12.89 volts and fully discharged at around 12.23 volts (assuming 50% max depth of discharge). 12V flooded lead acid batteries are fully charged at around 12.64 volts and fully discharged at around 12.07 volts (assuming 50% max depth of discharge). 24V Lead Acid Battery Voltage Charts
We discuss lead-acid battery capacity specifically in this post, although what follows generally applies to all electrochemical cells. A Conceptual Model for Lead Acid Battery Capacity. Battery capacity refers to what each cell can deliver, and this is of great importance to a battery user. We can imagine a battery having three compartments

When it comes to measuring battery capacity, there are two primary units: Ampere-hours (Ah): This unit measures the electric charge, and is defined as the amount of current a battery can deliver for one hour. It''s like the size of a fuel tank, but for electricity!
The capacity of the battery tells us what the total amount of electrical energy generated by electrochemical reactions in the battery is. We usually express it in watt-hours or amp-hours . For example, a 50Ah battery can deliver a current of 1
Usually the unit of battery capacity is ampere-hous (Ah) or milliampere-hours (mAh) for small batteries. T he unit of measurement itself shows that battery capacity is the product of constant current flowing through the load connected to a battery (in amps or in milliamps) and the discharge time in (hours).

The capacity of a lead–acid battery is not a fixed quantity but varies according to how quickly it is discharged. The empirical relationship between discharge rate and capacity is known as Peukert''s law.

Let''s assume we have a 12 V, 100 Ah lead-acid battery, and we want to estimate its remaining capacity using the OCV method. Create a voltage-SOC curve: We obtain the voltage-SOC curve for our lead-acid battery from the manufacturer''s datasheet. For simplicity, let''s assume the curve is linear and looks like this:OCV (V)SOC (%)12.610012
The capacity of a lead–acid battery is not a fixed quantity but varies according to how quickly it is discharged. The empirical relationship between discharge rate and capacity is known as Peukert's law.
To calculate the capacity of a lead-acid battery, you need to know its reserve capacity (RC) and voltage. The reserve capacity is the number of minutes a fully charged battery can deliver a constant current of 25 amps at 80°F until its voltage drops below 10.5 volts. The formula for determining the capacity of a lead-acid battery is:
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.
Battery capacity is a measure of the amount of energy that a battery can store and deliver. It is an important factor to consider when choosing a battery for your device or system. The capacity of a battery determines how long it can run without recharging.
The lead–acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté. It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead–acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents.
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.
