How to Change a Multimeter Battery

It takes you straightforward steps to change a multimeter battery. When you have found out that your multimeter battery is not charging, it is essential to change the batteries.

Changing the batteries will help it to start working again.

First, you need a screwdriver that is compatible with your multimeter. This is to help you be able to replace the battery easily.

Here are the other steps to follow to change a multimeter battery successfully;

  • Carefully remove all the probes attached to it and the covers
  • Remove the cover at the back of the multimeter
  • Carefully remove the old battery
  • Insert the new battery
  • Check if it has started working
  • Put all the probes and covers back

Now let’s get into explaining the above steps.

Carefully Remove All the Probes

The first step is to carefully remove all the probes and the covers of the multimeter.

The work of the cover is to protect it from getting internal damages. The cover also gives the multimeter a beautiful appearance since they come in different colors.

The probes are used to attach and keep all the multimeter parts together.

Remove the Back Cover

To remove the back cover, you have to use a screwdriver that can fit in the holes of the multimeter to remove the screws.

Removing the screws is very easy using a screwdriver. Your multimeter must have a horizontal line at the back that clearly shows where the holes are located.

Remove all the screws to let out the back cover. You should not force the screwdriver in the screws if it does not fit in well.
Forcing it will damage the holes or the screws, leading to more difficulties while removing them.

Carefully Remove the Battery

The back cover covers the battery since it is always placed at the back for almost all the multimeters. So after removing the back cover, now remove the battery.

Now here is the most important part of what we’re discussing on this topic.

Remove them with extra care to protect the multimeter from damage. The batteries can be placed at any angle and position.

Also, you should check the condition of the batteries. If batteries operate in a device for too long, they start producing some liquids.

The liquid can affect the multimeter when it gets to some of its exposed parts.

After removing these batteries with this condition, you should wipe the multimeter carefully and ensure no liquid is left.

You should never touch the liquid with your bare hands. If it lands on your sensitive body parts like the eyes, it might end up getting you into trouble.

This is because it tastes like some acid, and it should be avoided by all means. Therefore, avoid touching the batteries in bad condition with your bare hands.

You should avoid any damage to the multimeter since you want to make it work again by changing the batteries.

Insert the New Battery

After confirming that your multimeter is in good condition in all its visible internal parts, insert the new batteries.

The old and the new batteries must be of the exact specifications. If not, the multimeter might not work correctly and might not show accurate results.

You must ensure that these new batteries fit in properly. If they don’t fit well, you will not place the back cover.

Another tip to make the multimeter work is connecting the batteries’ polarities to the right multimeter’s polarities.

It is very hard to miss connecting the polarities since the wires are designed to be easily clamped without making mistakes.

Check if the Multimeter has Started Working

It is best to check if the multimeter has started working again before covering it. You might cover it and realize that it is not still working.

You will end up repeating the whole process of opening the multimeter and removing the batteries.

So, to avoid all this, ensure you check if it works immediately after fixing the new batteries.

If you find out it’s not working after placing the new batteries, remove them and fix them again. Do this several times. If the meter does not still work, change the batteries.

If it still doesn’t start working after all these, that means your meter is faulty. If it starts working again, then the multimeter is good to perform its measurements.

Put all the probes and covers back

When you confirm that your multimeter has started working, put the back cover and all the probes in their original place.

After that, put back the screws in all the holes to attach all the parts.


To change a multimeter battery, you need a screwdriver compatible to easily remove the screws holding together the multimeter parts.

The steps to follow are to change batteries are;

  • Remove all probes and covers
  • Remove the back cover of the multimeter
  • Remove the battery
  • Put in the new battery
  • Check if it starts working again
  • Put probes and covers back
