Follow these steps to measure the battery capacity: Set the multimeter to the DC current measurement mode (the symbol “A” with a straight line). Choose a current range that is higher than the expected discharge current of the lithium battery.
Here’s what you need to do before testing a lithium battery with a multimeter: Tools Needed: To test a lithium battery, you will need a multimeter (preferably a digital multimeter), a pair of test leads, and a fully charged lithium battery to compare the results.
One of the simplest and most effective ways to gauge a lithium battery’s health is by measuring its voltage. Voltage essentially tells you how “full” the battery is at that moment. Steps to Check Voltage: Set your multimeter to DC voltage mode. Look for a “V” symbol with a straight line on your multimeter’s dial.
To measure the current (in amps) of a lithium-ion battery, you need to set the multimeter to measure current (A). Connect the negative (-) lead of the multimeter to the negative (-) terminal of the battery and the positive (+) lead to the positive (+) terminal of the battery.
To determine if a lithium-ion battery is fully charged, you need to measure the voltage of the battery. Connect the multimeter to the battery and set it to measure voltage (V). Connect the negative (-) lead of the multimeter to the negative (-) terminal of the battery and the positive (+) lead to the positive (+) terminal of the battery.
Connect the probes: Place the red probe on the positive terminal and the black probe on the negative terminal. Read the voltage displayed on the screen. Interpreting the Voltage: A fully charged lithium battery (3.7V) should read between 4.1 and 4.2 volts when fully charged.

BU-904: How to Measure Capacity
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.
