First time poster. I have a bunch of 18650 batteries from an old laptop. I bought myself a Opus BT-C3100 V2.2 tester.
I would like to test the batteries but I’m wondering about the small weld nibs left on the top and bottom after removing the nickel strips. Should I remove the leftover nibs by grinding them off. I’m sure with them still on the ends there’s not a good connection in the tester.
Thanks in advance
