Will all DeWalt 14.4V batteries interchange?

Hi Bill,

Yes, all of the 14.4 Volt batteries will work with the 14.4 Volt tools. If you are upgrading to a different battery, such as the Lithium Ion batteries, you may need to replace your charger as well. The charger for your NiCD batteries wouldn't charge the lithium batteries, you would need to purchase a new charger. The new charger for the lithium battery would also be able to charge all of your nickel based batteries.

I hope this helps!

I have a Dewalt DC728S 14.4 volt Screwdriver. The black rubber or plastic sleeve/collar that you turn to adjust the mouth opening need replacing.

I need your help in identifying this part and where I may be able to get a replacement?

I really don't want to have to purchase another one because this has worked excellent for me and a replacement is somewhere around $100.00.

Thanks!

Yes I did, but it looks like the collar that adjusts the tension (because it looks narrow) and not the collar that adjusts the bit openning.

Now that I look at it closer, it's item number 5 (keyless chuck). Problem is I only need the black plastic cover and not the entire unit. The entire unit is $38.00 plus shipping. Guess I have to call them to get more info.

Unfortunately individual components of chucks aren't available. When those sleeves wear out you'll have to get a new chuck. Most power tool manufacturers don't build their own chucks, but buy them from Jacobs or Rohm for use on their tools.

Review: DeWALT - DC728
1 star
k_leenig@hotmail.com
When this tool works, it's fine. God forbid that the chuck should fail as it did on mine. I've removed chucks on drills for thirty years and never encountered one I couldn't replace before this one. The chuck that came with the drill literally fell apart in my hands when I went to change a bit. This should never happen. Even after investigating how to replace it on the internet, it seems impossible to do. Further, about twelve years ago, I bought two 14.4 dewalt drills and they still work fine--slightly different model. The batteries lasted a long long time while being used commercialy. I don't know what happened, but I've had bad luck with the new batteries that came with this drill. In one case, one battery wouldn't hold a charge at all, and the other doesn't last very long. I have four dewalt battery drills along with a number of other dewalt tool, and I'm thinking about completely switching over to another brand.

MY KEYLESS CHUCK FELL APART TOO. Dewalt should probably fix all the chucks free of charge.

I've had the same experience with my DeWalt batteries. I bought my first 14.4V drill when it came on the market, maybe late 80s or early 90s. One battery lasted until about 2000, the other about four years longer. I bought this same model drill at that time thinking I would have two new batteries to use with either drill. But neither has ever held a charge for more than 3 or 4 days. When idle. A normal day of D.I.Y. work will have one or the other on the charger at all times. Now the speed control failed, which is what brought me to this site. I guess when any product becomes a commodity item profit comes before quality!
