Yes you can fix it i have done 2 charges but white you are in there if you chance the large round capacitor to a 450v one you then can use the charger in 220 v you will have to increase the size of the voltage resistant diode to 240v (the vrd101 part in the charger) or by pass it with a straight bridge then the charger should work in 220v because the rest of the charger is exactly the same the parts will be around $10 ibought the parts from farnell

How you place 220 volts on it is a issue in itself. You can go onto ebay and get a new one for less than $25. Far less that what you would pay to ship the components that burnt out.

How do i convert a makita charger model DC18RC at 110 volt to 240 volts?


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 !

My charger is accidentaly connect into 220v and this is burn. im here in philippine. its this to repair and i use again...


Is this a 110Volt version that you plugged into 220v?

There is a ceramic Fuse inside the unit that might be blown. It is the first thing on the circuit board near the power cord connection.

Open the unit up and post a photo of any burned components ?

You can't use the same capacity as it gives you a very
large and expansive capacitor.
I used the max. diameter of 30mm that could go into the PCB of the model I have and it is 470uF 400V
You'll need to replace another capacitor, see my mod page !
This works !

DC18RA from 110v to 220v


The varistor you have to change is the one that runs parallel on the current after the fuse, in my case it was easy to find as it was the one with the plastic hood on it.

I'm going to update the webpage with some new pictures that I hope would hetp to clarify it.

Makita 18v 120volt american charger to be used in australia


Don't go buying more stuff when you can fix the problem yourself without buying any converter. The modification required to do it is very easy and most people wont have any problem following it.

You can go to this webpage where a detailed walkthrough is given (with pictures):
http://www.byggebolig.no/index.php?topic=5572.0

Some of the post are in norwegian but the walkthrough is in english.

Good luck and happy moding :)

P.S.

For those of you that have "blowed up" a makita charger 110v on a 220v, don't throw it away!
If you are lucky you have only blowed up the fuse and the varistor, which are easy to replace, and if you follow up the walkthrough you might even go all the way a mod the charger to 220v.

I know, I have already manage to "save" a blowed up charger.
