SOURCE: Makita DC18RA charger conversion

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 !

I added another HowTo page for modding the DC18RA from 110V to 220V , you can find it here
all the components details are in it

Have fun and good luck

SOURCE: Makita DC18RA Makstar Li ion Charger three lights

Alternate Red and Green flashing means bad battery. Buy a new one, or take it to a Makita Service center for replacement if it's under warranty.

Normally the yellow light indicates hot battery, but it could also mean dirty battery contacts so the heat sensor can't be read, or that the fan is clogged with dust and unable to cool the battery. The manual says let the battery cool and try again. If the yellow still flashes, it's contacts or the fan.

DC18RA battery loader is not working anymore.


Makita chargers are designed to check a battery before charging them. If both the red and green lights are flashing after you put a battery on the charger, it is reading a problem with the battery and will not charge it. It could be a bad cell, a problem with the circuit board, etc. but as long as it reads the problem it will not charge the battery.

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/

Red and green light flashes alternatingly with only one of my batterys of my makita 18v li-ion fast charger


unplug charger to let it reset. plug back in and then try again, if it still flashes red/green that would indicate a battery failure. check for warranty replacement.
