A battery is basically a source of voltage, and the voltage difference at the positive and negative end can be used to generate a current (and therefore provide power). This method is simple because if you know a full battery is supposed to be 2V, and when you measure the voltage you read 1V, then your battery is approximately half empty.

A battery's capacity can be estimated relatively accurately using a set of measurements and some complex math, but the most simple way to measure a battery's capacity is to measure the power going into or out of the cell. Power going into the cell would be charge testing and power coming out of the cell would be considered discharge testing.
Lithium Battery capacity relates to voltage. And a multimeter is a versatile tool that can measure both voltage and current. Here's how you can use it to test lithium battery capacity. What You Need: A fully charged lithium battery (e.g., 18650, 3.7V). A digital multimeter. A load (like a resistor or a small device to drain the battery). Steps:
Lithium battery capacity calculation Calculating the capacity of a lithium battery involves understanding a few basic principles. The capacity is typically calculated using the formula: Capacity (Ah)= Energy (Wh)/Voltage (V) Imagine you have a battery with an energy rating of 36 watt-hours (Wh) and a voltage of 12 volts (V).
Understanding the capacity of a lithium battery is vital for several reasons: Estimating Battery Life: Knowing the capacity helps you predict how long the battery will last on a single charge. This is crucial for planning usage, especially for devices you rely on heavily.
In fact, there are a lot of lithium-ion cell chargers that include capacity measurement as a feature. A low-cost discharge tester can be used to test the capacity of a battery that has a voltage between 1.2 volts and 12 volts. This means that it is well suited to operate at single-cell lithium-ion voltage ranges.
Testing lithium battery capacity helps you: Estimate Battery Life: Knowing your battery's current capacity helps you predict how long it will last before needing a recharge. Monitor Battery Health: Batteries lose capacity over time. Regular testing can alert you when it's time for a replacement.
