Broke the battery on my 20V Dewalt impact. Still works, just taped together. The battery I have isnt made anymore, and the replacement is $90 for one. I see all these off-brand batteries for half the price. Anyone tried them? I don't want to throw away money on junk if they are just that. But if I can get 75% of the usage for half the price I'll do that.

I have a  few from Amazon , they work Ok ,  no idea how long compared to "real Dewalt"  because I never had a fresh real one to compare , 

 I have then in the older 18v dewalt drills and sawsall , 

I would  check on how long the replacement time is if they fail to hold a charge , 

There are some Youtube videos that take them apart ,  you might look  there , 

Good luck

Cliffs notes:  Real Dewalt battery has approx 10x the energy.


That said, I was super skeptical of getting an off brand replacement for my Dyson, which uses the same damn cells as Dewalt, Milwaukee, etc.  but is $130.  I bought the $50 off brand and it. is. amazing.  Its possible I am just amazed because the one it replaced was such E36 M3.

The one I have is the original from 3 or 4 years ago. It still works good, just broke the case.

That was incredible.

And Bobzilla.  Buy an aftermarket battery, run it into the ground and then put the factory battery parts in the aftermarket case and go again.

Stanley Tools owns DeWalt and a bunch of others. I use DeWalt batteries in my Mac ratchet. I don't know how the prices break down, but maybe you can find a more affordable battery option within the family.
