Most of the outdoor power tools sold by Ryobi will usually require a battery to work. If these tools fail to work it’s probably due to the Ryobi 40v battery not charging properly. You will need to perform a series of troubleshooting steps to fix this problem.
Ryobi is a popular Japanese company that specializes in components for cars, electronics, and the telecommunications industry. In the United States and Canada, the company is best known for its power tools that’s sold at Home Depot and the internet. Some of the tools that it offers include drills, drivers, woodworking tools, and metalworking tools among others.
How do you revive a Ryobi 40v battery?
One of the common issues that you can encounter when using Ryobi cordless tools is the Ryobi 40v battery not charging problem. A fully charged Ryobi power tool such as the weed trimmer, leaf blower, or mower will usually work without any hiccups. When the lithium ion battery does not have charge then the power tool won’t work at all.
When the lithium ion batteries doesn’t charge then there are several factors that can cause this issue such as the Ryobi battery stuck in sleep mode, a defective Ryobi charger, a dirty 40v lithium ion battery or battery charger contact, or a defective old battery.
Method 1: Check for any corrosion on the contacts of the Ryobi 40v battery and battery charger
If your power tool, such as your weed trimmer or blower, gets constantly exposed to moisture then it’s very likely that its metal parts will develop rust. The battery contacts, which are made of metal, have the tendency of getting corroded when exposed to moisture. This corrosion prevents the flow of electricity which affects the charging process.
Try to check if any rust has developed on the lithium ion battery contact. If rust is present then you can get rid of this by using an extra fine sandpaper. Do the same for the battery charger as its contacts might have some corrosion as well.
Method 2: Check if the battery has entered sleep mode
When the power tool has not been used for quite some time the battery has the tendency to go to sleep mode. This usually happens if the lithium ion battery has been discharged to a certain low level. When you charge the Ryobi 40v system battery you might just see the red and green lights flashing on the charger. This means that the battery has been over discharged and the charger can’t detect if it is healthy or not.
To fix this you will need to have another charged Ryobi 40 volt battery available. Let’s call this the new battery and the one having an issue the old battery. You need to use a wire to connect the positive (+) terminal of the old battery to the positive (+) terminal of the new battery. Do the same to the (-) terminal. Leave this connected for around 10-20 minutes. What will happen is that the old battery will be charged by the new one.
Another fix option if you don’t have a spare Ryobi 40 volt lithium battery is to connect the battery charger to a power outlet. Place the battery in the charger until the green indicator goes solid then just before the red and green lights start blinking remove the battery from the battery charger. Repeat this step until the green light will get lit constantly.
Method 3: Check if the Ryobi 40 volt lithium ion battery is too hot or too cold
A Lithium ion battery will usually charge at temperatures between 32°F to 113°F (0°C to 45°C). Outside these temperatures the Ryobi battery won’t charge. If the battery is too cold like for instance if you leave the power tool outside in the winter then you will need to warm up the battery to room temperature before charging it. The same goes if you leave the power tool out in the summer then the battery might just be too hot. You will need to cool down the battery to room temperature first before you can charge it.
Method 4: Check if the Ryobi battery is old
The 40 volt lithium ion battery of your Ryobi tool has a set lifespan. The typical lifespan of a Ryobi battery or any 40 volt lithium ion battery for that matter is two to three years or around 300 to 500 charge cycles. A charge cycle is a period of use from fully charged to discharge then fully charged again.
If the Ryobi 40 volt battery is 3 years or 4 years old already then it will already suffer from degradation. It won’t be able to hold sufficient charge anymore or worse it might not be able to be charged anymore. The best thing to do in this scenario is to get a new battery pack.
After performing the steps listed above you will successfully fix the Ryobi 40v battery not charging problem.
