Really --- come on now

Your luckly they lasted 3 years

I'am not an engineer that can do a forensic
examine on your dead battery. So i don't know

The chuck screw on drills is put in with lok-tite and is reverse threaded. You need to get the screwdriver on it firmly and turn it clockwise, as you are, with strong, constant pressure until it breaks free. Don't let the screwdriver slide out of the screw slot, if you round off the screw head you'll have to cut the chuck off. If it still won't break free, try putting the drill in a vice or use a screwdriver with a hex nut molded into the driver shaft so you can use a wrench for some more torque.

Join the battery collectors club. I have 25 batteries, 12 guns, I quit buying the batteries, I found it cheaper to buy the gun with new batteries and charger once a year. Cause they don't even last that long. I have tried different brands too all the same. Got batteries?? Sure do.

The chuck has a left hand threaded screw inside. Turn to the right when removing the screw. Once the screw is removed you can remove the chuck by turning it to the left as it has standard, right hand threads. It is easiest to insert a large, L shaped allen wrench into the chuck, tighten the chuck, and hit the wrench with a hammer to spin the chuck off.

this is an unusual but not unheard of experience. I would try plugging the unit into a different outlet in your house, one that is not on that same circuit. If the problem presists even after that, take the unit or contact makita with the issue, they may offer you a replacement charger, its most likely not the battery.

I do not about a Makita, but my experience with other brands is when that happens, it means the battery is no good and needs replacing.

HI, Its ok for the charger to have those lights on. If you have been using for quite some time or the batteries have had several charges then the charger will operate a service on the batteries to keep them in good condition. We have had a few take as long as an hour to service , then it goes into normal charge mode. Just leave it on to do its service and it should be fine. If there was a problem then the red and green lights would alternate flash and a siren beep would sound. Hope this was of help to you.

I suggest you find a local industrial tool supplier who can test them for you. All of the industrial suppliers who service tools for contractors can quickly and easily test these batteries for you to determine the problem.

Often, this type of battery will drop in voltage so far that the charger will not recognize it as a battery and therefore will not charge it. Your nearest Makita service center can test, repair and replace the batteries. If they are within the warranty period, Makita will likely replace them, which the repair center will coordinate for you.

Big box type home centers can be a low cost place to buy tools, but they seldom service what they sell, so your town likely has a Makita authorized service center who will be happy to help you find and solve the problem with your batteries.

To find your nearest service center, visit Makita Tools and enter your zip code.

DO NOT Take the Batteries apart, you will see nothing more than a bunch of cells and if they are less than 1 year old than they may still be covered by Makita's warranty. Makita will Void that warranty if you open the batteries. Contact their service center they should be able to tell the age of your tool from the serial number or date code stamped in the tool. http://www.makita.com/en-us/Modules/Service/ServiceCenters.aspx or 1-800-4-Makita
If they are older than a year old you are out of Luck. While you cared for your tools, Hammerdrilling in general is an abusive application for batteries and will discharge the batteries quickly and reduce the number of recharges you will get on the battery. I always recommend people always use their cordless Hammerdrills only when corded power is not available

my guess would be that if you use them a lot and have had them in service between one a two years they may have worn out. they use plastic and metal in the gearboxes and the collar that rotates to change the gear can wear out. i see tools that are used to make a living wear out have to be rebuilt untill they don't make the parts anymore.

that is a pain. when you take them out they have to go back in that specific way that specific place. if you don't get back just right the case won't fit back together. if you take it slow and only remove what you need to remove you may not have any trouble. you will have to remove all the case screws to get to the gearbox. everything is a tight fit.

contact Matt Price at [email protected] or call 225-262-6245. he is a makita dealer and can get and ship parts. he also handle warranty work.

They torque them on there so it won't fall off under hammer use, they never know what you will be doing so they don't take chances. You will have a tough time getting that thing off, why do you want it off anyway?

open the jaws-remove any bit and look down inside-you'll see either a hex or phillips head screw. It will likely be left hand threads so be careful. It should come right off but you might need to lightly pry it off.

NO!
