my dewalt dc011 radio will work on the batter or the 120 plug but wont charge batteries and i get 53 volts dc output from the charge port while plugged in and drains a fully charged battery in twenty min volume doesn't matter only the power on will drain it wtf is going on
TOTALY wrong forum. A radio is NOT a power tool!!!
Your battery is dead or almost dead.
It appens if you let it totaly discharged for over a day.
It also slowly loose it's charge over time and need to be recharged every 6 months of storage: The charge may drop to zero and it kills the battery.
