First measure of the batterie if its loaden ,only if the brushes are to short replace also anyway the armature and brushes BOTH . it is not good to switch only the carbonbrushes because of a marketing technical design concept because of the heat dissipation that playing tricks insite the armature and it is cheap made by Johnson
sometimes the half value compared to other brandnames.

Armatures are new designed in a short time

drill is not working - 23465970-2oroqqetjko0hjqmfukebeah-4-0.jpgleft the armature of the old but same cdd 18 milwaukee no problems you can change only the brushes and its working again right the same modificated armature marketing technical a new design of this JOHNSON Armature (Johnson is also used in Panasonic powertools bv EY7441 ) it has much more force in the same armature but the heat dissipation plays tricks and if the brushes are to short replace anytime BOTH (the brushes and the armature look at the difference of the turns of the coil front right look the later design more and thiny wire on it more power force but a bad heat dissipation in about 2 or 3 years the brushes are on its end take by heavy work a more powerful tool its better longlasting then this machines Makita has oft a better armature but there are also posibillities in some tools.

The battery is 14.4 volts so the charger should be 14.4 volts.

My dc18ra makita battery charger flashes red and green lights no matter how many bateries i try


The pcb inside the battery has a microcontroller that monitor the charges and charge cycle. When the cell falls below a certain voltage, it will instruct the charger not to charge and will show with a red-green flashing light. If the battery has been tried 3 times in succession then the pcb will brick itself from the makita charger. So first replace the bad cells. There are 2 solutions at this moment: charge with a 3rd party lithium charger like the imax b6 or replace the pcb with a working one. check out my blog on http://mkbl1830.blogspot.com/

I've got a Bosch ps30 drill that uses bat411


Directions say green light indicates that the battery is fast charging only,it does not indicate at exact point of full charge. I let my batteries charge for 12 hours for the first time charging,found out myself the same way. Try that and you will notice the difference.

It tells you to that you should charge the battery


The problem is your batteries are either over heating or worn out. You might also have a problem with the charger but you'll need Dewalt tech support to determine if it's good or bad.
The first thing to do is clean the contacts. Use a white plastic pencil eraser and clean all the contacts you can reach. If there are any contact you can reach with the eraser use a Q-tip that is just damp (not wet) with rubbing alcohol to clean them.
Discharge your batteries completely then put them in the freezer for 8-24 hours. Take the batteries out of the freezer and let the set 24-48 hours after that put them on the charger, they'll either charge or you need new batteries (more likely) or a charger.

Green and red light comes on when i put battery in charger what does that mean?


Here is the manual:
http://toolboyworld.com/eBay/Ryobi_P120/P120_566_eng.pdf

Red = quick charge
yellow = evaluating
green = charged

CHARGING A COOL BATTERY PACK
If battery pack is within normal temperature range, the red LED on charger will come on.

Red LED should remain on for approximately 1 hour then the green LED will come on. Green LED on indicates battery pack is fully charged and charger is in maintenance charge mode.

14.4V Drill Battery Will not Charge


The battery is 14.4 volts so the charger should be 14.4 volts.

Yellow / green light will not go off when charging


Its likely the batteries will take at least several hours to fully charge, if not more. NiCad batteries are slow charging and usually need 4-6 hours for a full charge. Keep them on longer or even overnight but make sure you remove them in the morning. You will probably find the light turns green after 4-6 hours of charging. If lights stay yellow and green after 12 hours of charging, it may indicate a fault in the battery itself where it will not accept a charge.
