I had the same problem. You need to manipulate either the speed or the torgue. In some cases both. Sometimes the drill/hammer feature gets stuck in between the two an this is the only way to fix it unless taking it apart but I wouldn't do that yourself. Best to take it back to the dealer or service shop
TRY THIS TAKE THE DRILL REMOVE ALL SCREWS OPEN IT
FIND THE POSITIVE AND NEGETIVE ON THE MOTOR HAVE A 12 VOLT BATTERY AND 2 CABLES 1 RED 1 BLACK 6 F-LONG 1-CONECT THE POSITIVE CABLE TO POSITIVE ON BATTERY AND NEGETIVE TO NEGETIVE ON BATTERY NOW YOU CHECK THE MOTOR ON DRILL BY TAKING POSITIVE AND CONNECT TO POSITIVE ON DRILL AND NEGETIVE TO NEGETIVE ON DRILL IF THE MOTOR RUNS THE PROBLEM SHOULD BE SWITCH.YOU CAN BYPASS THE SWITCH SOLDER THE WIRES TO THE MOTOR AND USE IT IN THE MEANTIME. SCREW THE CASING BACK TOGRTHER
YOUR DONE VERY SIMPLE..
GOOD LUCK.
sounds like the battery is bad and not taking charge.replace battery attemp again if not then check for fuel, spark and compression.then c wat happens or wats not working any motor no matter how small or big has to hv those three things to run. hope this helps.
Your problem states you have a Makita tool and your question is about a Dewalt lithium battery. In either case if the battery won't take a charge or if the charger is showing the battery is defective the only fix is to replace the battery. Some causes for defective batteries or batteries that won't take a charge are bad cells in the battery, bad or shorted IC board in hte battery, broken or burnt connections between the many cells or between the cells and IC board or even bad or old cells that will no longer charge up. The time and effort needed to find out what the problem is then finding another battery to scavenge parts from (individual battery parts are not available) is never worth the cost of just buying another battery and going back to work with the tool(s).
Rechargeable batteries do have a lifespan, they won't recharge forever. If you have fully discharged the batteries then fully recharged them and they still don't have full power or they only last a couple minutes then they are done. If they won't charge or the charger shows them as defective, the only fix is to replace them.
I have to agree, I assume you have tried the the same battery on both chargers? is it possible that one charger ruined all the batteries? I wish I could offer some real help other then to say "hmm." But my best guess is that one charger ruined all the batteries. unless you use them both at the same time, then it would be hard to have them all quit at once.

Push the battery in and out while pressing the trigger on the the drill to see if there is a loose connection here. Check
the terminals inside the drill and the battery terminals
.These sometimes become tarnished and don't make contact. Clean with
very fine sandpaper.
I leave my 18 volt batteries charging year round even if I do not use my drill I switch batteries about once a month to keep them both up to snuff. your new chargers are made to do that unless the instructions tell you not to. I was told even new batteries will not hold their charge if allowed to completely run down and stay there.
Yes. It's kind of like a flashlight when your batteries get low the light get dim, but if you replace the batteries light gets bright again. The drill will get weak as battery get low.
