diagnose the problem

If your Ryobi's battery will not charge, the first step is to diagnose the problem.

First make sure it is well connected to the charger. You may need to try plugging it into a different charger or outlet.

Once the connections are secure, try charging it for a few hours as it may be completely drained.

If that doesn't work, you may need to disassemble the battery and check the connections.

Check the charger

Make sure it is plugged into an outlet and the charger indicator light is on. If not, try a different outlet or connect the charger to a different device to ensure the output voltage is correct.

When the indicator light is on, unplug the charger and reset it by pressing and holding the power button for 10-15 seconds. After this time, plug it back in and try charging the battery again.

If you have multiple chargers, try each one on different outlets to make sure none have stopped working properly. If you don't have multiple chargers, borrow one from a friend or family member, or purchase one from your local Ryobi dealer or hardware store. This is important as sometimes they will not charge if connected to a weak or unbalanced charger.

Check the battery

Before attempting any other diagnostics, make sure you are getting the correct voltage. Using a multimeter, set the meter to measure DC voltage (denoted by a volt or V symbol). Place the meter probes on two of the battery posts and take a reading. Depending on the type, you should get a reading between 12V and 18V. If you're getting more or less than that range, it's likely not charging due to a faulty charger or adapter.

If the voltage is correct, the next step is to check if there is current flowing through it. Using the same multimeter configured for DC (denoted by an amplifier or the symbol A), attach a test lead to each terminal and measure between them. The current should be somewhere between 0-1 amps for Li-ion batteries and under 0-4 amps forBatteries NiCd/NiMH.

If you are not getting voltage, you may not be getting enough current. However, if you are getting adequate voltage levels but no current, there may be a problem with one of your cells or connectors. To ensure optimal performance of your Ryobi battery, please ensure that its cells are free of corrosion and that its terminals are securely connected and making good contact with their respective poles when in use.


In this section, we'll cover some common Ryobi battery problems and possible solutions to fix them.

Let's take a look at the most common reasons for not charging, from faulty chargers to damaged battery connectors.

Clean battery contacts

Battery connectors are designed to deliver consistent, consistent power by providing an electrical connection between the battery and its charger. Unfortunately, if these contacts become dirty, corroded or damaged, the charging process can be interrupted. To ensure a permanent connection, you should clean the contacts regularly.

To properly clean the Ryobi battery contacts, you must remove dirt and debris. Start by removing any dirt or debris around the contacts with a soft-bristled brush. If there is visible corrosion, use grade 000 steel wool to scrub it off. After removing any residue, dry the contacts with a lint-free cloth before reinserting them into the charger. Once inserted into the charger, make sure both connections are secure and have no gaps or gaps that could interrupt the charging process and prevent your tool from working properly.

check the voltage

When troubleshooting a Ryobi battery that will not charge, this is the first stepcheck the voltage. You must use a digital multimeter or voltmeter with proper safeguards to measure battery voltage. The voltage should not be less than 20V for a fully charged battery. If it's smaller, that means it needs to be charged to work properly.

Once you've determined that it needs charging, you'll need to determine what type of charger is compatible with your specific model. Most of them require a dual output AC/DC charger for optimal charging results and long-term protection.

Once you have determined the correct voltage and charger settings and found a suitable power source, connect the charger and begin charging according to the instructions in the manual for your specific mode. Please note that while all batteries require some form of paring system, Li-Ion and LiPo models are particularly sensitive and require special care during charging cycles, including using defined trim levels such as 4V/cell or equivalent whenever possible.

After connecting all components required for charging (power supply/adapter and charger), wait until charging is complete and follow any additional instructions (e.g. turning off the heating module before completing the last charging cycle) . When finished, unplug it, unplug items in reverse order (i.e. unplug power first before unplugging) and store individually according to the instruction manual before use. use them again.

Check the fuse

If your Ryobi tool battery will not charge or turn on, first check the fuse. The Ryobi tool battery contains at least two fuses that you must manually check to ensure they are working properly.

The first fuse is near the battery and can be accessed by removing the screw that holds it in place. If this fuse looks good, you'll need to remove the fuse cap on the other end. This cover opens to reveal another fuse that may need to be replaced if it looks bad.

It is important that these fuses have continuity and are tight in order for the battery charge indicator lights to function properly.

After checking both fuses, try charging them by plugging them into a compatible charger and allowing enough time for a full charge. If your Ryobi tool still won't turn on after replacing a blown fuse, there may be an underlying issue with the charger or your tool that requires professional servicing.
