18650 negative terminal slightly deformed from removing nickel strip

[Jonk8id]

I removed the nickel strips from the negative terminal using diagnal cutters. I grab and roll to remove the metal. I noticed on some of the tough ones the negative terminal raised. I ran a capacity test using an xtar vc8 plus and its in the 2700mah range. bat spec > 2500mah. it is hard to see in the image but there is a high spot from trying to pull the strip off. Can these be used? Eventually it will be used in a powerwall.

I am not an expert on working with 18650 batteries but the seal is on the positive side so that should still be perfectly intact.

I was worried that since I moved the negative terminal housing it may have done something internally. Are there any other tests I can run to verify they are OK?
