How To Fix Common Ryobi 40v Battery Problems - Explore further
2021-10-22u2002·u2002Hello Aaron. I have 2 40 volt ryobi batteries with a similar problem. The first one showed as faulty on the charger. I eventually tried a different charger and it took a charge! I used it one time in my trimmer and charged it. It showed a full charge but wouldn't work again. It's showing 19 volts more or less with a volt meter.
