Plastic tabs break

Great battery holds a charge forever only use it with my stubby impact has great power but the plastic tabs break off and crack to where they are unusable. Very frustrating

Broken tabs on case-I just got this thing!!!

Batteries themselves (capacity) are very good. Within one week of use, BOTH sides of the battery case broke (tabs). This is not good. Plus, I can't find a replacement case for the life of me without ordering one from China. However I should not have to do this!!!! I have 5 M12 tools I use regularly. None are abused. This is unacceptable!

My “go to” batteries for my high use tools at work

They last me all shift long and then some for lighting and drivers. Seems they are getting harder to find in stores, but I’ll find more and add more!
