Question about Drills

3 Answers

I have a 14.4V B&D Cordless Drill and many power packs but don't remember which one is the right one

What voltages should be shown on the charger if the Drill is a 14.4v battery. the B&D replacement part # is 5103069-07 but they don't say anywhere what voltages (and amps) should be the output of this Charger.

Please help

I have the same drill and have the charger in my hand now....the actual output rating is 17.4 V with 120V input (a bit higher than above answers as some regions have 110V or 115 V service). I am absolutely sure (I had misplaced my charger for a year and have just located it this past week!) Good luck.

The charger should say no more then 14.4 volts. The actual output may vary and be as high as 15-16volts to ensure the battery gets a full fast charge. Similar to your car battery its a 12volt battery but your alternator will put out up to 16volts to keep the battery fully charged. Make sure your charger is rated for no more then 14.4 volts to avoid any possible over charging/heating. It may show lower if a universal charger (say 7.2v-14.4v) if it charger multiple battery sizes. Some even charge larger batteries (like 14.4-24v). Any of those chargers with more then one voltage range is fine. You just don't want to use one that only says 18v. Normally the manufator makes the tips a little different so you cant insert a 14v battery into an 18v charger only but don't hold it to that rule. Always double check for your safety and to avoid damaging the battery

I,m trying to find charger for a kraft tech 18v cordless drill. Can anyone help?


Hello,
there are two components require to charge a kraft tech 18v battery.
A power pack (power suply) and a battery station. The power pack says 24v DC 400mA but produces 34v DC at no load. When the power pack is connected with the battery station a green led lights at the battery station and the battery station produces 32.4v at no load( i mean without put the battery on to battery station. I believe that if i put the battery at the battery station the voltage drops to 24v DC, which is the voltage that the power pack says. I'm sorry but i can not measure the voltage that produced from the battery station when the battery is on it because my battery is dead and has shorted elements.
I hope that was useful.
Greetings from Hellas (aka Greece)

Revive drill driver battery packs


Rechargeable batteries do have a lifespan, they won't recharge forever. If you have fully discharged the batteries then fully recharged them and they still don't have full power or they only last a couple minutes then they are done. If they won't charge or the charger shows them as defective, the only fix is to replace them.

Charger wont charge batteries for cordless drill


Check the charger output, it should be about 4-5 volts higher than the battery pack voltage rating. If the charger voltage output checks ok then the battery pack is defective. Any Radio Shack store can test the charger for you.

Dead DW972 Cordless Drill?


Easiest and safest: take the tool and batteries to nearest shop where they sell Dewalt. Ask the guy to let you use their batteries in your tool and vice versa, your batteries in their tool. DYI procedure:To check batteries: - if you have some multimeter, try to measure voltage and if possible also amps (but only for a fraction of the second, if battery is good, amperes shoudl jump up very quickly) - if you have no multimeter, try to find 12V bulb (check spare bulbs for your car), use wire to connect and it should light up. To check tool: open it up, take some 12V DC source, put wires on contacts inside the handle where battery connects. Pull the trigger and it should work. you can try to put wires directly to contacts on the motor. Follow cables from the switch to motor.
