DC18RA battery charger i.c number

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.

You are saying it got wet?

my battery charger ic broken for a.c power flechuvation so iam not seeing that i.c number so i will ask you model DC18RA

Why can't you buy the 230 volt DC18RA charger in europe (amazon.europe country) and use it. I had the same issue yet i burned out the fuse in the 110 volt DC18RA charger because i plugged it into the wall just using an adaptor. Lesson learned. Therefore, my first solution was that i bought a converter from 220V-to 110 Volt. This showed me that my charger was done. So instead of getting another 110 volt charger sent here to Europe from Canada, I returned the converter and have on order a 230 volt input DC18RA charger from amazon.de which has the same 7.2-18V output. I have been told this will work yet the fear, and I don't know why, is that it will burn out the batteries in a year or so. It is difficult getting specific information from Makita, but I hope it all works out. Best of Luck for you

Return to store for replacement.

dc18ra has a fan for this purpose, I woudn't change anything in this unit
check to see if your fan is working

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

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.
