A higher voltage means more drilling power but it can also mean more weight - don't buy a drill you won't need, 12 volt drills are powerful enough for most home users, bigger models just weigh more so think carefully about what you will be using the drill for.

I might add that the new dewalt drill that uses the new nano (lithium ion) batteries weigh less than their nicad counterparts. They also do not develop memory that shortens the life of nicad batteries.

Can i charge a 18v dewalt battery useing a 12 volt and a 6v chargers wire


I would say that this is a bad idea. A tool charger is designed specifically for the battery, and kluging it like that is a good way to fry something.

I need to replace the transformer inside my 12 volt charger. I can not find who makes the ES -66-287rev5 transformer. Need help.


If you have the skill to determine the transformer input is open, I would expect you have the skill to replace a transformer. Based on this assumption: determine the input voltage (120 vac?), determine the output voltage (14 vac?), determine the power requirements (output voltage times the charging current), find a transformer at www.digikey.com or www.mouser.com or www.newark.com.

Craftsman 1425301 charger won't charge batteries


If the battery voltage goes down below 90% of the rated voltage the charger is programmed to not accept it for charge as it may have a fault. If you can bring the voltage up enough it may take another charge but is probably faulty.

Charger wont chare batteries


Two reasons:
Either the battery has developed reverse polarity or is weak and so does not take up charge .
If so you can try and check voltage after charging and see if this dropping off on load. If so replace battery.
secondly the charger can be faulty and will not produce the current/voltage required for the battery to charge . If so check the circuit and rectify with a voltage check.

How I can convert 110volts to 220 voltage in Craftsman charger 145301 because in the Peru country we use 220 v. thanks.


_Some_ chargers will allow a range of input voltages. This will probably be "Input: 100-240V" or something like that written on the charger. __You need to be sure__. Others may have a switch from one voltage to the other. The trick here is to make sure the switch is in the right position. In both cases you may also need a plug pin adapter. If the charger you have has neither of those abilities then you either need to get a different charger from Craftsman, or get a voltage converter, which will give both the right plug for your wall sockets and convert from 220V (from your wall) to 110V (to the charger). Unless the charger has voltage range or a switch, you can't just use a simple plug pin adapter.

My battery charger doesn't charge. Any ideas?


You will to have your charging current/voltage checked in the first place., Use a multimeter and check the voltage of the adapter,. Next remove the drill unit and check the voltage on battery pack with the adapter and without. If there is increment of voltage on the battery then the charger seems to charge and your battery can be the suspect.
Change with the same AH rating.

My makita drill is weak/ has no power. I checked the 14.4 volt battery with a voltmeter, and it is fully charged, and the brushes are still good as well. Is the motor bad? Any idea what could be wrong with...


did you check the battery under a load condition?as in check the voltage under drill operation,most batteries will check their normal top charge voltage when not being used,this is known as a surface charge,but under load the voltage may severly drop leading to burned or overheated armatures,have it load tested

Battery charger not working


make and model would help, general help do you have voltage tester? if so look at charger and find voltage output, test contacts and if lower than listed charger has gone bad, also clean all contacts with pencil eraser to make sure they are clean on battery and gun, if charger is good and contacts clean either battery is bad test in another device or test voltage, if battery good the drill is bad
