Makita DC1804T charger

My batteries and charger are about 18 months old and have had little use. Lately my batteries recharge from flat in around 10 minutes but are not fully charged even though the green light comes on, ie., they don't last very long in use. Is there a way of adjusting the charger to ensure a full charge?

SOURCE: faullty makita DC1804T charger red lights keeps

I think if you have a battery that is pretty much dead, the Makita charger will never fully charge it and so it blinks. My newer battery charged up in 1/2 an hour but my old-as-the-hills one just keeps on blinking. I removed it and it works. It never really held a charge long though, for years now. It would be nice if the charger had some kind of manual telling you what all those universal symbols(I don't know who's universe they're talking about) mean.

Between us my son and I have 10 18 volt batteries for our Makita power tools which we use in our Carpentry work of these 10 batteries 6 have failed. I have to say the reliabillity of the Ni-cad equipment...


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.

Both batteries show full charge but don't last 10 minutes. Only had the tool for less than a year.


rechargeable batteries can build a memory, if you use it say for 5 minutes and then put it back on the charger - then the next time you use it for 5 screws and put it back on the charge - see where I am going
Over time the rechargeable batteries "learn" they only have to work for 5 minutes ( dang my son was that way)
You need to fully drain them and recharge them fully several times might take 10 times.
We have a program in our shop that when you are done with a battery it goes in the flashlight until dead, dead, dead then to the charger. I have batteries that are 10 years old and still work almost like new.
You may have to replace yours but it is worth a try
