Question about Makita BDF452HW 18V Cordless Lxt Lithium Ion 12" Driver Drill Kit
Batteries are defiantly working ok and brushes are also fine.
Your most likely problem is the switch (PN 650583-6). When they go bad they will let power go to the LED light but it won't get to the motor. With a multi-meter, check the power going into the switch and coming out to the motor. If 18 volts are getting through to the motor then you may have armature (PN 619198-8) issues.

did you check the battery under a load condition?as in check the voltage under drill operation,most batteries will check their normal top charge voltage when not being used,this is known as a surface charge,but under load the voltage may severly drop leading to burned or overheated armatures,have it load tested

If this is a newer tool it is probably a Torx drive screw usually a T20. The screw is LH thread and after removing it you will need to put some screws back in tool to remove the chuck. First shift the gear selector to the low setting and the clutch to the drill only. Next get a bent handle allen wrench about the capacity of the chuck install the short end of wrench in chuck and tighten. Put the chuck on a block or wood or a workbench to support is and turn the wrench to about a 30 degree angle in the counterclockwise position. The chuck has standard threads so you want to hit the wrench with a hammer to loosen it. This might take a few tries but it will work. Good luck

I think your tryiong to charge NIMH batteries oon a charger designed for Lithium Ion batteries. With all the new style batteries such as NICAD, NIMH and LI-ION, charging becomes difficult. Most chargers pre NIMH and LI-ion, were designed for NICAD's. The best advise, match your batteries with the correct charger
