The individual lithium battery cells inside even genuine Dewalt tool battery packs do not hold up as well as Samsung (Milwaukee) or Panasonic (Tesla) cells.
The worst individual cell ruins the entire pack.
The newer Harbor Freight battery packs fit Dewalt tools - but I do not endorse them.
Interesting.
In the early 70's, during the summers I worked construction. in their constriction yard out back sat unused a large 1950's era Dewalt 16" radial arm saw. I bought it for a $100. It was a monster and a very nice piece of machinery I used for decades; it made me a lot of money.
I scoffed at Dewalt when they first decades back entered the battery tool market. Little did I know what was in their future.
