How to Test a Ryobi Battery Charger

Ryobi is one of the more affordable and reliable brands. If you happen to own products from the company, it would not come as a surprise. Although, after a time you might notice that your battery is not holding a charge. There are two possibilities for that to happen. Either the battery is dead or the charger is faulty. If you suspect the latter, then read this guide on how to test a Ryobi battery charger.

Numerous brands sell tools and equipment as Ryobi does. They also have some really good equipment and are durable. But it seems that this brand does something right which attracts most people to it.

Why Choose Ryobi Products in the First Place

Ryobi is a famous brand, one of the preferred brands for people wanting to work on projects at home. They have a wide variety of products and they are all pretty affordable. The best part is, all of their products and tools use the same batteries. Meaning, the battery slot is identical in all of their products.

While some brands have different batteries for different products, which makes them less reasonable and affordable. But on the other hand, Ryobi products use the same batteries for all products. All of their batteries, regardless of the hour ampere, have the same construction. Just that the higher capacity batteries are heavier and bigger.

That is not the only reason though as to why Ryobi is so popular. Another reason for its surging popularity amongst people is affordable pricing. And if you just buy one high capacity battery for all products, you are good to go. This saves you tons of money on buying different batteries for different products.

It also provides you with a great warranty on their products. This gives the customers assurance that they are not being ripped off with cheap products. As only a company that has faith in its product gives a good warranty for it.

How to Test a Ryobi Battery Charger

If you have a suspicion that your Ryobi Battery Charger is faulty, then there is an easy way to test it. All you need is to get your hands on a piece of electrical equipment called a voltmeter or multimeter.

This is fairly common and is always present in an electrician’s equipment bag. It is really easy to use and with just a little knowledge anyone can use it. If you follow this step by step guide you will be able to find out if your Ryobi battery charger is working fine or not.

Step 1)

Since most Ryobi batteries have an 18 Volt output that is also going to be the output of the charger. Since you already know that, it is easy to know where to set your voltmeter dial. But in case you are checking out any other charger, make sure to find out the voltage on the specifications.

Step 2)

First thing first, you should know that a charger converts AC to DC. So you would want to change the dial of your voltmeter to DC. And since Ryobi chargers have an 18-volt output, you will need to set it above the limit. For instance, if the lower limit of the dial is 10V and the upper is 20V, set it to 20V.

Step 3)

There are two wires with probes sticking out on one end that are attached to the voltmeter. The red one is a positive probe while the black is a negative probe. You need to make sure that the red probe wire is placed in the socket that denoted V on the multimeter to measure voltage.

Step 4)

After you are sure that you have the idea of what probe goes where it is time to test the charger. First up, plug your charger into an electrical outlet. Basically, you are going to test whether the charger is providing the batteries with enough power to charge or it’s faulty. For that, you need to plug the charger in.

Step 5)

Afterwards place the positive probe, the red one, on the positive terminal of the charger where you put in the battery. The positive side will be marked with a positive sign. Then place the black probe on the negative terminal.

Step 6)

If you are getting something above 18V, do not fear. It is normal for any charger rated 18V to provide more voltage to charge batteries faster. This is just how most chargers are. But if the voltmeter indicates something less than 18V or no voltage at all, then there is something wrong with your charger.

In this case, the wise course of action would be to either claim warranty if you have any left. The other course of action would be to buy a new charger if its warranty period has expired.

Things to Keep in Mind While Testing Out a Ryobi Battery Charger

  1. Always make sure that your voltmeter is set to the proper current. There is AC or alternate current that you get from wall outlets. Then there is DC or direct current that most battery-powered electronics use. So if you are going to test a charger’s terminals for voltage, always use DC.
  2. Make sure your probe wires are plugged in the proper place. The black probe should always be plugged into the socket that says COM. While the red one should be inserted into the socket indicated with a V for voltage. This is specifically for those multimeters with multiple options.
  3. Make sure you place the probes on the proper terminals. Check the terminals to see whether they are indicated properly by their respective signs.
  4. Wear insulated gloves to avoid any electrical shocks while working with electronic equipment. Also, make sure you are wearing rubber boots or that your feet are not directly in contact with the ground.
