How To Test A Ryobi Battery Charger

Cordless battery tools are becoming the new normal. Products like the Ryobi Batteries and the Ryobi Battery charger are nothing less than revolutionary. Such products save you from a ton of hazards and also benefit the environment. 

But as good as they might look, there are a lot of problems associated with them. The charging problems and the fact that you can not repair such appliances only increases your frustration. Because of their irreparability, Ryobi battery chargers are hard to test. If the charger won’t charge, you can get confused because of the reason behind it. You never know if it’s the battery or the charger. 

In this guide, we will guide you on how to test a Ryobi Battery charger. There are two methods of doing this: 

  1. Test the charger with a good battery, or 
  2. Check the output voltage of the charger by using a voltmeter/multimeter. 

Read on to learn about these methods in detail. 

The Required Equipment 

First of all, let’s clarify what you’ll need to test the charger. There are no large equipment requirements to perform these tests, but you do need: 

  1. A Multi-Meter/Voltage Meter
  2. A good battery (tested or in a working condition)

Please keep in mind that you do not need both of these at once. Only one is required to complete the test. Although, if you want to test the charger with both the methods that we are gonna share, you will need both at once. 

How To Test A Ryobi Battery Charger

Method 1: Test It With A Good Battery

The first method to test your Ryobi Battery charger is with the help of an already working/good battery. There’s no rocket science to it. Just connect the charger with the battery and look at the indicator LEDs. Here’s the complete list of outputs and what they mean: 

  1. If the green LED is blinking with the red LED slowly becoming brighter, the charger is working fine. It means that the problem was with your previous battery and not the charger. 
  2. If the green LED is still on and the red LED goes off, the battery is fully charged. In this scenario, the Ryobi chargers automatically enter a maintenance mode. And, if the green LED is slowly pulsing, the charger is switched to what they call an ‘energy-saving’ mode. 

Although, one other result may pop up. That is when the red LED has a slow pulse. It means that the battery has a fault. It will probably not happen if you’re testing the charger with a known, already tested good battery. 

Method 2: Check The Output With A Voltage Meter (Multi-meter)

The second method to test a Ryobi Battery charger is to check the output with a voltmeter (alternatively known as a multi-meter). You can buy a voltmeter for about $15 from any store near you. To test your Ryobi battery charger with a voltmeter, you would need to perform the following two simple steps: 

Step 1 – Gather The Equipment 

First of all, you need to gather the required equipment. It would include your battery, the charger, and the voltmeter. 

Step 2 – Connect The Voltmeter With The Correct Tabs

Before connecting the voltmeter with the charger, make sure to set it to DC mode with the range of 10 to 30 volts. It is the standard-setting when checking the voltage output of a battery. 

Now, plug in the charger to the power outlet to switch it on. Find the connector tabs of the charger. There should be four tabs in a Ryobi Battery Charger. Two tabs do not have any negative or positive signs. While the other two have one negative and one positive sign. Connect the tabs with the cords of the voltmeter. 

When you connect the red cord (probe) with the positive tab, you will see the total voltage output of the charger. At first, the output will jump very high. But after a few seconds, it will come down to the actual number. 

If the voltage output is 1mV, then the charger is fine. If it is less than or more than this, there is a problem with the charger. 

Things To Keep In Mind While Using A Ryobi Charger

Cordless Ryobi Chargers are great to have in your battery toolbox but there are certain things to take care of while using such tools. If you own a Ryobi Battery Charger, you should be aware that: 

  1. You can not repair it yourself. If after testing the charger, you concluded that there is a problem with it, do not go ahead and try to repair it. If you do so, you may damage it for a lifetime. Even though these cordless chargers are not made to repair, we recommend you take them to a battery/auto repair shop. 
  2. Keep them away from water. Most of these chargers are not waterproof, and placing them uncovered at places where there are even splashes of water can lead to a short circuit. Therefore, we recommend you keep them away from such places in your home or office. 
  3. Keep them away from extreme cold and heat as well. Exposure to extreme heat can even lead to the chargers getting burst. 

To Sum It Up

The cordless chargers from Ryobi are extremely efficient and nice to have. But, you need to take some extra care while using them. When you can not charge your batteries with the Ryobi Charger, make sure that the problem is with the charger. We hope that this article will help you test your Ryobi Charger and decide if the problem is with your charger or the battery.
