How to Test Lithium Ion Battery with Multimeter

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. The multimeter will display the current (in amps) flowing through the battery.

Understanding the basics of the 12V system

The last test is another voltage drop test. This time, you will place the positive lead of the meter on the battery positive post and the negative on the positive starter post and engage the start position, record your voltage, and compare to the specification. Again, the specification can range from 0.2V - 0.5V.
