Question about Makita Drills

1 Answer

This drill has been sitting around the garage for years. I bought a battery for it and placed it in the re-charger. After moving the cord around, the red light came on and after an hour of so I checked it, and tha battery was very warm. However, when I put it in the drill, nothing worked? I saw the video on jump starting the mortor. I read the post that said it either the on/off switch or the motor normally. Should I take everything appart and clean everything, the re-assemble and test? How do I test the battery using a meter that does voltage/current? It was not used much, what else can I do? Thanks.

Pull it apart and clean the drill. I'm sure condensation has accumulated, if it's been sitting. You can test battery with voltmeter - DC volts

My battery charger just does not work anymore! I have the two batteries and charger that were purchased as a package with my drill. I bought many other pieces to add to my Ryobi family.


Receipt will do nothing for you if it is out of warranty. Normal warranty is for three years.

Write to the company regarding your situation - see if your unit has a serial number that can give indication of age of unit. Perhaps they will replace the charger for you.

Make sure that the charger cord/connections are good and that unit is receiving power from wall.

I have a 24 volt cordless drill and the charger won't work. I bought another drill and soon after that the other charger packed up,has anybody else had this problem and how can I fix them.


I have had several drills using Ni-cad batteries in a battery pack. The charger is just a transformer that steps down the voltage to just above the battery rating say 18V battery would have an AC output of 20-24 VAC and then a small diode is placed across the positive lead to block the negative cycle, thus giving you one cycle of the sine wave to charge the battery. You could probably open up the device and replace the diode. That is if you are using Ni-Cad batteries.

Not so with the newer drills that use Li-ion batteries. Those batteries present a safety problem as if they are charged too rapidly they will over heat and the lithium catches fire. To prevent this a chip is incorporated in the battery pack to stop the charging cycle if the batteries in the pack fall below a certain threshold, as this will cause the charger to push more amps into the battery, because of the low voltage present, and this would heat up the battery too much, possibly cause a fire. So the chip signals the charger, "Do not turn on" The Li-ion batteries start to loose their ability to hold a charge. as soon ras they are built. about 6% a month. If that battery was manufactured last year then it was already down and if you let it sit for a long period of time it looses it's charge because of the parasitic draw of the windings in the motor. The batteries could have gone down so much that the chip locked them out to the charger. The charger is a whole lot smarter than the old ones.

Purchased the two lithium and charger combo about two years ago. I use my Ryobi drill and flashlight in the garage and around the house no where near commercial/professional levels. About three (3)...


How long have these 2 batteries been standing idle without being charged? Lithium ion batteries can still discharge if left for too long. There is a voltage detector which detects whether the cells are too far discharged to be safely charged again and if that occurs the circuit is broken and the batteries will be deffective in the charger.
I have had the same problem with these and other LI batteries. Answer is replace the batteries and then make sure they are given a quick charge on a regular basis. However common advice seems to be that LI's should not be kept fully charged, but just partially charged until needed, then charge them for use, especially if usage is sporadic

Drill wont take a charge or operate, drill 9089 10mm type 3, 6 volt


9 times out of 10 problems like this are the result of a bad battery, in other cases it can be a bad charger. Without knowing more information I cannot give you an exact diagnosis. This is the first question I ask when approached with this issue, Has this drill been sitting for a period of time and if so, was the battery charged before it was put away? If Yes, the drill has been sitting and No, it was not charged are your answers than chances are your batteries are dead. This tool has Ni-Cd batteries that self discharge as they sit, eventually these batteries discharge until they have nothing left. In addition, if the battery is stored in a cold garage/shed will speed up this self discharge. I always tell people to think of their power tool batteries just lie a just like a car battery that dies if it sits too long without being started.
If you do not use your power tools on a regular basis it is recommended to fully charge the batteries before storing them or else they will self discharge until completely dead. Another option is the newer Lithium-Ion power tools batteries are not as temperature sensitive, have a much slower self discharge and can sit for 12-18 months before starting to loose their charge.
A replacement battery for this drill runs about $42 plus s/h and can be purchased directly from Black & Decker (1-800-4-DeWalt or www.dewaltservicenet.com) My recommendation is to purchase a new drill. For around $40 - $50 you can buy a newer upgraded model with new battery and charger.
If you think your issue may be something else, please feel free to ask. If you feel I have helped explain or resolve your issue than please rate me. Thank you

Makita DC1414 schematic


From my experience most chargers do not have replacement parts. And when you do find a schematic for a battery charger it consists of just the cord and housing, and the printed circuit board is not available. This is the case with this model DC1414. The cord and housing are the only things available for replacement. You can purchase a new charger for around $37. If you have any questions please post back.

Makita dc1804f charger will not charge new i-mh 1834 18v battery


I think your tryiong to charge NIMH batteries oon a charger designed for Lithium Ion batteries. With all the new style batteries such as NICAD, NIMH and LI-ION, charging becomes difficult. Most chargers pre NIMH and LI-ion, were designed for NICAD's. The best advise, match your batteries with the correct charger
