My 24v new makita drill doesnt hold charge - Makita 6408K 3/8" Variable Speed, Reversible Drill with Case

replace battery or buy a new tool

I have a 12v an 18v Dewalt I can charge them both from the same charger

Is that with the 24v batteries? Where would you be? I'm in Australia, and Makita doesn't sell anything with 24v batteries here. however there seems to be a few going on the UK ebay site. I hope that helps.

i bought a new makita cordless drill in united states of america brought it home to the republic of ireland got a 110 adopter to recharge the battery but it will not hold the charge would it be the flight home have wiped the batterys what do i do?

The DC24SA will charge 9.6V to 24V Ni-MH slide style batteries (1.7Ah to 3.3Ah)

DO NOT Take the Batteries apart, you will see nothing more than a bunch of cells and if they are less than 1 year old than they may still be covered by Makita's warranty. Makita will Void that warranty if you open the batteries. Contact their service center they should be able to tell the age of your tool from the serial number or date code stamped in the tool. http://www.makita.com/en-us/Modules/Service/ServiceCenters.aspx or 1-800-4-Makita
If they are older than a year old you are out of Luck. While you cared for your tools, Hammerdrilling in general is an abusive application for batteries and will discharge the batteries quickly and reduce the number of recharges you will get on the battery. I always recommend people always use their cordless Hammerdrills only when corded power is not available

contact Matt Price at [email protected] or call 225-262-6245. he is a makita dealer and can get and ship parts. he also handle warranty work.

You indicate that the drill is new. I'd suggest you return it for a replacement. Seems to be a defective or wrong charger. If you have problems and If you paid by credit card call the card company and have them stop payment on that charge.

As long as the charger voltage and the battery voltage match (7 volts) there should be no problem. A fast charger just runs more current thru the battery (per unit time) than a not-so-fast charger. If you notice the battery getting really hot when it's charging (like too hot to touch), stop using it.

How old is the battery?
They have a service life and require replacing after they no longer hold a charge. This could be 2 years or 8 years depending on how often it is used and how regularly it is charged etc.

If it is a new battery, then take it back as it could be defective.

Possibly could also be the charger but you could verify that by charging a different battery and seeing if it charges that second battery ok, or not.
