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

Bought two new batteries for my 18v cordless drill makita mxt 8444D. Batteries are 2.6 Ah 1834 NI-MH. The charger is Ref DC1804F. When inserting batteries into the charger the green and red light flashes alternately. This would suggest that the batteries are faulty - however, they are brand new.

That is the correct charger for either nicd or nimh batteries. It should work. Even though your batteries are new, they could be old stock, and they degrade sitting on the shelf. Return the batteries.

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

Switch and bateries

Makita makes two 12V Ni-Cad pod batteries: Battery 1222/2.0Ah (PN: 192598-2) and Battery 1220/1.3Ah (PN: 192681-5). Makita's universal charger (PN: DC1804) will charge any Ni-MH or Ni-Cad pod or stick battery from 7.2V to 18V.

Makita 8444d second and third gears sound noisy and do not engage

I had the same problem on my 8444, it was out of warranty (just over 2 years old) so I stripped it and found the plastic gear selector ring worn out. Was livid at this as these drills are marketed on the strength of the "all metal" MXT gearbox! Makita UK, to their credit, sent me a replacement gearbox free of charge when I pointed this out to them.

A year on and the replacement gearbox has now started doing the same in 3rd (high) gear. Doubt I can get another free 'box out of Makita (they would probably say I fitted it incorrectly) so am looking at buying just the drill body, which comes out at around £60 and will work with my existing batteries. Just not sure if I would trust the replacement not to fail, but a similarly powerful drill with 2 batteries would cost me wel over £200.

Dc1804f charger

If you have tried discharging the batteries prior to charging them already with no result and from what you describe in your post, then I would have to say the charger has issues. Go to HD or Lowes (not sure if Lowes carry Makita) but another charger and test your battery again. If you get the same fault, there is an issue other than the charger, if not you need a new charger anyway. If you get the same fault with the new charger, you can always return the new one. Short of opening up the charger and using a volt meter, this is the easiest way to test to pinpoint the real problem. I hope this helps and good luck!

My AEG BL9618 battery charger has started to chirp(beep) is this a fault signal as the user manual is pretty thin on troubleshooting

Does the battery still charge?? The reason I ask is that some tool mfr's are starting to play with the chargers. Insert the battery and remove within 5 seconds and reinsert and then does the noise go aaway or change? Makita has started doing this and also some others. If the battery charges I wouldn't worry too much but try the above method and see.

I bought a new highter current ni cad for my makita; however, the

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.
