SINCE I BUY THE DRILL ONE OF THE BATERIES IS NOT CHARGING

The first thing to do is get your volt meter and check if there is any voltage coming from the battery and compare that to what it is stopped to be. If the voltage is ok, install the battery in the drill and try to run it. If it won't run, you've got a bad drill. Next install the battery in the charger and plug the charger into your wall outlet. There should be an LED which flashes to indicate that it is charging. If you can get a full charge on the battery (verify this with your volt meter), try it in the dill again. If the drill will not rotate, there is definitely a problem with the drill.

this sounds like a battery issue. but it could be a charging problem too. check to make sure the charger is putting out the correct voltage to charge the battery,, if it is - then I would just buy a new battery and the drill will for fine.

Change or buy a new batt.

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.

If Li-ON batteries, they will act as described when about to need charging.

Hello the alternator is not charging the bateries ,the rectifire in the alternator is gone,the alternator have to be change

your batteries have possibly developed a memory and are probably shot or it may be the charger local toolstore should be able to test them both.Which ever one is bad it will cost more to buy a charger and battery than it will to buy a new drill .whatever you do ask the shop people how to stop the battery from developing a memory or if you want to come back to me when you have them fixed up I will be happy to tell you.please let us know how you get on ,thankyou

From what i know these are deep cycle bateries. If you recharge after every use its run time becomes shorter and shorter. If you want a long run time let it run down before you recharge
