Makita 18V LXT... | Answered on Nov 25, 2019

Some of the Makita 18v LXT tools require the BL1830 3.0AH battery and are designed that the 1.5AH battery will not fit.

Makita 18V LXT... | Answered on Sep 14, 2019

What has happened is the hex part of the bit has twisted slightly making it hard to remove. What I would do if you are comfortable with partial disassembly is remove the quick release mechanish. There is a split ring that comes off first and then a washer and spring, next remove the outer collar and SMALL steel ball from side of chuck. I take a pick (dental tool) and push up or try and twist the stuck bit. Sometimes it takes while but usually this works. Let me know if I can try and help further.

The brushes are probably wearing out. They can also smoke if they get dirt or something on them. You can take the drill apart and replace the brushes, but if they are just burned some, take some fine sand paper or emery cloth and polish the armature where they run and clean the brushes and reinstall.

On the Makita 18-V DC18RA charger, the flashing red light means that the battery is not at the correct temperature for safe charging. If the battery is hot (from use or being in direct sunlight), charging will begin when the battery cools down. If the battery is cold, then charging will start when the battery warms up. (Note: the cold battery could have moisture condensation issues. This could delay the start of the charging cycle.) Home Depot has the manual for this charger here: . I suspect that Makita uses the same "code" on all of their chargers.

I hope this helps.

You can try to recharge batteries and see if they work by placing them in tool. If you are using Ni cad batteries and charger, you would better served by going lithium ion batteries.

I’m not sure if you can buy a new c/board .
The charger tests the battery before charging & if it picks up a fault it won’t charge the battery. At our repair shop we just replace the whole battery ( under makita warranty if it’s under two years old / depending on what warranty your country has )

Unfortunately, Makita’s li-ion battery packs have a design flaw. After having the same problem with my two batteries, I took it apart and saw the problem immediately. You see each battery pack has ten li-ion battery cells and a circuit board with a memory chip witch holds the charging history of the battery pack. But that memory chip constantly draws power from 2 of the 10 batteries. The current it draws is very small but if you consider it over 8 month or more, the power drain becomes very significant. You end up with a battery pack with 8 still fully charged battery cells and 2 drained battery cells. When you put this battery pack in the charger, it detects weak battery cells, assumes they are defective and refuses to charge. To avoid this problem you should charge your battery pack often, even if you haven't used it, every two months should be ok.
I suspect that Makita doesn’t make these battery packs, they make power tools, good ones too. Buy Makita should definitely have a few words with their supplier before they become a liability!

The DC18RC are most likely to charged the BL1830 battery, which is the most popular of 18V Makita power tools. It is a Li-ion battery.

And the DC18RC battery charger has two volt 110 Volt and 240 Volt.

The 240 Volt DC18RC charger can replace model DC18RA & DC18SD because of its improved performance and full compatibility with Makita's NEW 'Star' labelled batteries that communicate between the tool, battery & charger. And, it is a fast charger.

It can charge a Makita BL1830 Battery in approx 22 minutes.

But, I do not recommend to convert a makita charger model DC18RC at 110 volt to 240 volts.

The reason is as below:

1. This will void product warranty ! If you follow this mod, you do it on your own risk !

2. There are several comments that described
same model # but with different design and components.
Please beware that this mod might not work on your charger
or worst, will damage it.
Only perform this mod if you know your way around with electronics !

Yes, there should be a couple of tiny holes in the brush holders you can push tiny Allen wrenches in to hold brushes back against springs to clear armature to assemble.

go to and type in your model number and you should be able to download a schematic, if you have a problem let me know and I will go another route for you.
