Ryobi Ryobi RY401018 40V 20 in. Brushless Push Mower BATT DEPLETED Error Fix: Battery Fully Depleted — No LEDs Lit

No LED indicators light up when the battery fuel gauge button is pressed, and the tool does not respond to the trigger. The battery is fully discharged. Place the battery on the Ryobi 40V charger. The charger LED should turn solid red (charging). A deeply discharged battery may take several minutes before the charger recognizes it — leave it on the charger for at least 15 minutes. If the charger never lights up, try cleaning the battery terminals with a dry cloth or compressed air — debris or corrosion on the terminals can prevent electrical contact. If the battery still will not accept a charge after cleaning, the cells may have been over-discharged below the BMS recovery threshold and the battery needs replacement. To prevent deep discharge, recharge the battery when the tool performance noticeably drops rather than running until the tool stops completely.
