OK, perhaps I should have known better, but I bought a couple of look-alike M-12 batteries on Wish.com. They look fine and fit, and ran the tools fight out of the box. But when I tried to charge them on genuine Milwaukee chargers (3 different chargers) the Wish batteries caused red-green flashing code for faulty batteries. They seem to charge anyway, but maybe not as fully charged as they should.
does Milwaukee put some sort of kill-pill in their batteries or chargers to prevent counterfeit batteries from working with their tools or chargers? Is there a fix for this issue?
