How to check battery voltage?
Batteries need both voltage and current, but testing voltage is easy — all you need is a multimeter , also known as a DVOM (Digital Volt and Ohm Meter). Plug the leads into the multimeter. The black lead will go into the port that says “COM” (common ground) and the red lead will get plugged into the port that has a capital “V”. Turn the multimeter on to the 20V DC section of the scale. (If you have an autoranging meter, just go to “V,” because you won’t have a scale.) With the bike completely turned off, touch the black lead to the negative post of the battery, and the red lead to the positive post. Record the voltage.
