What Should a 6 Volt Battery Read on a Multimeter

Some applications and a few recreational vehicles such as wheelchairs, golf buggies, and motorcycles, need 6V batteries to function properly. Learning how to read the voltage is necessary to maintain your battery.

You can measure your battery voltage with a multimeter and your 6v battery if charged fully should display a reading between 6.3 and 6.4 volts.

Voltage readings can help you estimate the charge state of a 6-volt battery. If you open a 6-volt battery, you will notice that it has three different cells. Each of these cells has a capacity of around 2.12. When fully charged, the whole battery pack should give you a voltage reading of between 6.3 and 6.4 volts.

Do you want to test if your battery is still producing six volts? Here is a guide on using a multimeter and the reading you should expect.

What Voltage should a 6-Volt Battery Read? 

To determine what should a 6-volt battery read on a multimeter when it is in good condition, follow this four-step guide.

  1. Check the 6volt battery and establish the two battery terminals’ polarity. Each battery terminal has a clear label – Pos/+ for the positive terminal and Neg/- for the negative terminal. Depending on the battery design, some terminals may exhibit small plastic colored rings around their base, simplifying identification – red for positive, black for negative.
  2. If your multimeter has variable settings, set it to measure 0 to 12 volts. The multimeter comes with colored wires attached, namely red (positive) and black (negative). Metal sensors are on the end of the wires.

  1. Touch the red wire sensor of the multimeter to the positive battery terminal. The black wire sensor should touch the negative battery terminal.

  1. Study the digital meter display to take the voltage reading. If your battery is in good condition and at 20% charge, the digital meter display should read 6 volts. If you get below a 5 volts reading, charge the battery.

What Should a 6-Volt Battery Read on a Multimeter when Fully Charged?

Voltage readings can help you estimate the charge state of a 6-volt battery. If you examine a 6-volt battery, you will notice that it has three different cells. Each of these cells has a capacity of around 2.12. When fully charged, the whole battery pack should give you a voltage reading of between 6.3 and 6.4 volts.

Are you wondering how long it takes to have a fully charged battery? A regular 6-volt battery should take approximately six hours to obtain a full charge. However, if charging it for the first time, leave the battery to charge for ten straight hours. Doing so maximizes its service life. (1)

Wrapping Up

Testing a battery helps you ensure that it is in good condition and can provide enough power to the electrical system in question. If you have a 6-volt battery that isn’t holding a charge, you don’t have to worry. Now you know how to obtain the voltage reading of a 6-volt battery and how to obtain that reading using a multimeter. Depending on the reading you obtain, you’ll know if your battery requires replacing or not. (2)
