Trying to find out which batterys will work in the DC720 drill driver??? Scott

The only way to get it off now is with a grinder and metal cutting wheel. Lock the drill body in a vice with the chuck out of the vice jaws. Wear safety goggles and do not stand or let anyone else stand in the plane of the cutting wheel while cutting, you will have lots of sparks and if the wheel breaks peices will stick into things. You have to make a judgement call but you want to cut just at the head of the stripped screw. It's a lot of steel to get there so be patient and work carefully to remove the tip of the chuck. Once the tip is cut off you may be able to grab what's left of the chuck with a vice grip or lock it in the vice and turn it off the drill. If not, you'll have to make a cut length wise in the chuck so you can split the base and remove it. Be careful not to go deep enough to cut into the anvil or back far enough to cut into the drill body and trans. After making the cut put a chisel in the cut and hit it, hard, until the chuck body splits.

Sometimes places like Batteries + and the Battery Barn (on line web sites) will have replacement batteries for popular models even after the manufactures quit producing them. That is where I found batteries for my Bosch drill.

IT DEPENDS ON THE SIZE AND LOCATION OF THE POSITIVE AND NEGATIVE METAL STRIPS
AND CLIPS ...SOME WILL FIT BUT NOT WORK BECAUSE OF THIS...DO NOT TRY UNTIL YOU HAVE CONFIRMED THIS....YOU CAN RUIN IT BY TRYING WITHOUT LOOKING.
.....I HAVE SAME PROBLEM WITH DIFFERENT DESIGN...IT WILL FIT PERFECT BUT THE STRIPS ARE DIFFERENT...................HOPE THIS HELPS.....................METALPOET

Hi,
The chargers also go bad... in this case being that all of the batteries are showing bad I would be getting a new charger and trying that out...

You stated you have a 12V Cordless Drill with PA14 batteries. The PA14 battery is 14.4V. The battery may fit in your tool and might work for a while but the motor isn't made for that battery. The way to check the batteries is to try them in another charger, any 14.4V to 18V pod/stick charger will work. The way to check the charger is to try another battery, any good 7.2v to 14.4V pod/stick battery will work. Unless the charger got wet or extremely hot the problem is usually the battery. Just check to make your tool and battery voltage is compatable.

Try placing the battery in a freezer for six hours before trying to charge the battery and if this doesn't work find a friend with a working charger and make sure using that method that you don't just have a bad charger.

I found the Ryobi charger fits the jobmate as well.

charger is most likely stuffed get it tested at a battery world or the like .it can also mean the battery is stuffed

There are three visble screws and one hidden. Use the right size torx driver if you have it, or a small allen wrench works too and undo the screw that is visble on one side of the pack. Snap the false bottom off of the pack and reveal two more screws to remove. One screw is behid a plastic cap over a fourth obvious screw location. Drill the cap and unscre this screw also. Be sure there are no lables holding the two side together. Pressing down on the battery holdin clasp makes the sides easier to separate. Watch for falling parts. That's it!
