How To Test A Cordless Drill Battery Charger | Wise Guide

Test a cordless drill battery charger is now no more an enigma for familiar people. Now cordless drill has become quite an essential tool that exists almost in every home for DIY projects. 

The cordless drills are handy tools that make working more straightforward and more convenient. Also, they are lightweight as well as easy to use. Their cordless features allow you to take them anywhere anytime and perform your task accurately, even in dark and tight spaces.

But because cordless drills are cordless and don’t need a connected wired power supply to perform their jobs. They are based on batteries to fulfill their power and energy requirements. 

For a continuous battery result, you must have a good battery with a well-performing charger. Sometimes, a battery charger can create multiple issues and stop charging a battery even with good energy and power supply.

By test a cordless drill battery charger, you can easily understand if the charger has a problem or the battery itself has an issue. 

This article will guide you about how you can test a cordless drill battery charger. We used to explain the whole procedure into simple and easy steps. So let’s begin the process without further delay.

TEST A CORDLESS DRILL BATTERY CHARGER | REQUIRED THINGS

To test a cordless drill battery charger, you must have some essential tools that make your work easier. 

MULTIMETER

The first piece of equipment that you need the most to test a cordless drill battery charger is a multimeter or voltmeter. With a multimeter or voltmeter, you can quickly identify the actual state of voltage in the battery. Aso, it helps you to run various tests on a battery charger. 

Note: We prefer you to use an advanced multimeter because it measures the total amount of voltage and amperage and measures resistance and capacitance.

RUBBER GLOVES

Safety comes first, that is why you should have to wear a pair of rubber gloves to protect yourself from any sudden mishap. Make sure the gloves should be rubberized because rubber cannot conduct electricity.

ELECTRICITY SUPPLY

Last but not least, to accomplish your task ideally, you need a source of electrical power. By which you can test the workability of the charger.

HOW TO TEST A BATTERY CHARGER WITH A MULTIMETER | STEP BY STEP PROCEDURE

STEP 1: For the very first, you have to know the exact voltage rating of your drill’s battery and charger. You can quickly learn that by seeing them on your drill’s label. Otherwise, you can effortlessly search them on the manufacturer’s site by using your drill’s model number.

STEP 2: Now, Set the multimeter to receive the same voltage as your battery charger. The multimeter can be adjusted to increase its voltage. Just like, set your multimeter’s voltage capacity at 13 V if your cordless drilling battery has a voltage rating of 12 volts.

STEP 3: After setting the multimeter with your battery charger. It’s time to plug the battery charger of the power drill into the source of electricity. So we can further test its workability or issue.

STEP 4: Now, it’s time to connect the wires with suitable terminals. Make sure that you double-check the cables and airports to get better and accurate results. Connect the multimeter’s red wire to your battery charger’s positive metal terminal outlet. Connect the multimeter’s black wire to your battery charger’s terminal for the negative metal. A circuit board is also an option to connect the multimeter’s batteries to the charger.

STEP 5: To determine if your battery charger is functioning efficiently, you can use the multimeter. Double-check your results by reading again.

STEP 6: The voltage reading on your multimeter should be higher than the charger’s overall rating if the battery charger is functioning correctly. If the voltage reading on your multimeter is lower than the overall voltage rating for your cordless drill battery charging charger, it could be a problem.

STEP 7: You should keep the cordless drill charging device in a safe place. If the voltage reading is lower, you’ll need to look for a replacement charger. Your battery charger may not be working correctly if your battery isn’t charging correctly.
