If, after applying the recommended steps, the Ryobi battery still does not respond, it can be a result of the following The solution to do this is to get a new Ryobi 40V battery pack. If your battery has stopped working or retaining charge and lasted for over four years, it might be a sign that it is old and needs to be replaced. The lifespan of a Ryobi 40v battery is about 3 to 5 years, that is, between 300 and 500 charge cycles.
You can use a longer tool to scrape off the rust. Some batteries have terminals in a position that is not easy to reach. You can get rid of the rust using sandpaper or with a wire brush and alcohol-soaked wipe.
Rusting around the terminals impedes contact between the wires. Corrosion in batteries causes a build-up around the terminals, which can insulate the conductive parts. The Ryobi battery charger could detect the battery as faulty if the terminals are corroded. On the other hand, if the battery has been in heat for a while, you can keep it in the fridge or a cooler place for a while and try charging it up afterward. If you store your battery in a very cold area, take it out to a warmer environment to warm up a bit, then try charging it. If you are having issues with your Ryobi battery, check if it is too hot or cold. Usually, lithium-ion batteries charge at temperatures between zero to 45 degrees. Recent battery models like the lithium-ion types work at a narrow temperature range. Leave it connected for a while this should take it out of sleep mode and allow the battery to charge. Connect the positive output to the positive terminal of your battery and the negative output to the battery’s negative terminal. Use a DC power supplyĮnsure the DC power supply is set at the same voltage as your battery. Doing this could take the battery out of sleep mode. Connect the terminals using wires in matching polarity, that is, positive to positive and negative to negative Leave them connected for a few minutes and then try charging the battery again. Ensure the second battery is healthy, fully charged, and of the same voltage as the one in sleep mode. You can use another fully charged battery to jump-start the sleeping one. It might take up to 30 minutes before the green light flashes constantly.
This is the easiest and safest method to wake up a sleeping battery. Also, the Ryobi chargers do not have a boost that revives a battery that has entered sleep mode. The charger reacts this way because it cannot determine if the battery is healthy and would rather not charge but gives the warning flashes instead. This problem can be fixed, so you do not need to replace the battery. When you try to charge the battery, the charger will flash a red and green light. When the battery enters sleep mode, it is difficult to charge it, as the charger cannot provide enough power to bring the battery back to life. This is the most common reason for a Ryobi battery to fail, and this happens when the battery has discharged so much that it has been used till it is flat and left for a long time without charging.
