Sounds like your battery is sucking the power as a heater...

Disconnect it ( the battery ).

Rick is correct that drill barely turns at 1Amper that is 1000 ma and
will draw 8 to 15 Amps under full load..


My batteries are dead, I'm trying to convert my drill into a power drill. The DC converter I bought must not have enough power at full load. The batteries labeled 2.6ma but it must put out more amps.

Does the drill run normally on it's own battery?

2.6 mA ( I assume you don't mean Mega Amps (MA)!) is very little for a cordless drill

I would expect it to draw Amps when in use. this would explain why your mA power supply won't turn it the power supply is current limiting.
