Why Is My Ryobi Charger Flashing Red. The most common cause for your Ryobi 40V Charger showing flashing red and green lights is that the battery has been over-discharged. I was excited to get these babies charged until I was met with a blinking red lig.
If the red LED light is flashing and the green LED light is off the battery is being tested. What do the lights mean on a battery charger. Another brand of charger a car jumper pack or a Battery Tender or similar if you have one may send enough amperage to the battery to revive it.
Just so why is my Ryobi battery charger blinking red.
Time it so that you can disconnect the battery from the charger before the green and red lights start flashing 4. Going strictly by the book that flashing red light means your battery is defective and wont hold a charge. Now plug in the power cord to a power outlet and let the battery charge for at least 48 hours. This could occur if the battery pack is initially too hot or cold when placed in the charger.
