Given the problems with Makita Li-ion batteries there are 2 likely reasons, you have a faulty charger or both batteries are faulty, the best option is to find another charger to try your batteries on and see if they charge, depending on the age of the drill you may be able to get the batteries or charger replaced by Makita, a lot of them have been replaced out of the warranty period because they are known to fail prematurely, take the faulty item back to the place of purchase with you invoice and put the pressure on for replacement

The switch will need to be replaced

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.

charging steady red then flashing red overheating and green red flashing replace battery.

Lithium batteries do have a life span determined by how many times the battery is discharged and recharged and how hard it is worked on the tool. Batteries get hot while charging and discharging and heat is what ages batteries. Lithium batteries, depending on usage, will last from one to three years. I've seen some last five years but that's rare. They also have numerous cells and a circuit board that can go bad and kill the battery. Chargers are designed to check the battery's condition and won't charge a battery if it detects something wrong. If your battery is under one year old, it's covered by the warranty. If it's over, you'll have to buy a new battery.

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?

Open the chuck and remove the screw inside the chuck (if fitted) the screw is left hand thread, fit the short end of the largest hex key that will fit into the chuck and tighten the chuck, put the drill into low gear and turn the clutch to the drill position, support the drill on a bench and strike the long end of the hex key with a firm blow (right hand thread) it may be neccessary to strike it more than once

check switch it may have over heated and burned out

If the batteries were good before you might have a short in the switch, which can sometimes take out the batteries.

Return it to the place of purchase if under a year or send it to Makita UK in Milton Keynes

After removing the screw lock the short end of a 3/8" to 1/2" allen wrench in the chuck. Firmly hold the drill on the edge of a bench or lock it in a vice so you can strike the allen wrench hard and fast. The screw is reverse threaded but the chuck turns lefty loosy like a regular nut and bolt. It's the best and only way to break the chuck free.

Makita says that is a switch problem, not easy to fix

Your problem states you have a Makita tool and your question is about a Dewalt lithium battery. In either case if the battery won't take a charge or if the charger is showing the battery is defective the only fix is to replace the battery. Some causes for defective batteries or batteries that won't take a charge are bad cells in the battery, bad or shorted IC board in hte battery, broken or burnt connections between the many cells or between the cells and IC board or even bad or old cells that will no longer charge up. The time and effort needed to find out what the problem is then finding another battery to scavenge parts from (individual battery parts are not available) is never worth the cost of just buying another battery and going back to work with the tool(s).

The chuck screw on drills is put in with lok-tite and is reverse threaded. You need to get the screwdriver on it firmly and turn it clockwise, as you are, with strong, constant pressure until it breaks free. Don't let the screwdriver slide out of the screw slot, if you round off the screw head you'll have to cut the chuck off. If it still won't break free, try putting the drill in a vice or use a screwdriver with a hex nut molded into the driver shaft so you can use a wrench for some more torque.
