What should a 6-volt battery show on a multimeter
Content
Some applications and a few recreational vehicles such as wheelchairs, golf buggies and motorcycles require 6V batteries to function properly. Learning how to read voltage is essential to maintaining your battery.
You can measure battery voltage with a multimeter, and your 6 volt battery, if fully charged, should read between 6.3 and 6.4 volts.
The voltage reading can help you assess the state of charge of a 6-volt battery. If you open a 6 volt battery, you will notice that it is made up of three different cells. Each of these cells has a capacity of about 2.12. When fully charged, the entire battery should show between 6.3 and 6.4 volts.
Do you want to check if your battery is putting out six volts? Here is a guide to using the multimeter and the readings you should expect.
What voltage should a 6 volt battery read?
To determine what your multimeter should read on a 6-volt battery when it is in good condition, follow this four-step guide.
- Check the 6V battery and reverse the polarity of the two battery terminals. Each battery terminal is clearly marked - Pos/+ for the positive terminal and Neg/- for the negative terminal. Depending on the design of the battery, some terminals may have small colored plastic rings around the base for easy identification: red for positive, black for negative.
- If your multimeter has variable settings, set it to measure from 0 to 12 volts. Colored wires are connected to the multimeter, namely red (plus) and black (minus). Metal sensors are at the ends of the wires.
- Touch the red lead of the multimeter probe to the positive terminal of the battery. The black wire sensor should be touching the negative battery terminal.
- Examine the digital meter display to take a voltage reading. If your battery is in good condition and 20% charged, the digital indicator should show 6 volts. If the reading is below 5 volts, charge the battery.

Are you wondering how long it takes to fully charge the battery? A typical 6-volt battery takes approximately six hours to fully charge. However, if you are charging it for the first time, leave the battery to charge for ten consecutive hours. This increases its service life. (1)
Summing up
Testing the battery will help you make sure it is in good condition and can provide enough power to the electrical system in question. If you have a 6V battery that won't hold a charge, then you have nothing to worry about. Now you know how to take a voltage reading from a 6-volt battery and how to take that reading with a multimeter. Depending on the reading you get, you will know if your battery needs to be replaced or not. (2)
