Guess I have to make that anonymous 
I had mods (Joyetech eVics) that made scratches (actually circular grooves) in the base (negative end) of batteries. It was the spring, which had a sharp end sticking up. I just curled the sharp end down a tiny bit, and no more scratches. You might want to investigate what is causing the scratches and see if it can be fixed.
In my eFest LUC V4 charger I set the base of the battery against the moveable part and push it back (with the battery) and slide the positive end down against the fixed terminal. I lift the positive end away to remove the battery. Even if there was a sharp edge on the negative terminal, it never slides against the base of the battery, so it doesn't scratch.
I have a battery question that seems almost too silly for the battery forums. I know about not using a battery with a damaged skin, but what about scrapes at the negative end? I don't seem able to avoid these, both in and out of the charger and going in to the battery compartments on the Wismec Reuleaux RX75s that I'm switching over to. The scrapes are either on the flat negative surface or on the outside edge at the very 'shoulder' between the cylinder and the flat. I'm sure hoping I don't need to re-wrap for these, becauseit's almost every battery charge and change.
Now, to be absolutely safe, if the charger is your issue, get a new one. If it's a matter of 'handling', be more careful.
My ol' Nitecore was not the most kind on my 18650s...
Minor scratches on the metal end of a battery I don't see any concern, but if the wrapping is in any way damaged, that should be rectified immediately.
What dey said ... yep

I'm constantly walking over to my LUC 4 and checking progress. When I rotate the cell the voltage rises a little from increased metal to metal contact. I've thought about smearing a film of De-Oxit on the charger contacts to prevent oxidation and minimize contact resistance.
When I insert cells I put the negative post against the bay contact and push back to compress the spring, then ease the cell into the positive as you described. To remove, I use a fingernail to slide the cell back and up. The negative contacts are rounded bumps, so there's not much to cut the wrap, but the positive has a bump with a small center hole for increased contact.
Negative end shouldn't be a problem. On the positive end the case of the battery is covered by the wrap. If the positive end wrap is cracked and/or peeled back there's a chance that positive and negative could be shorted by metal contact across the two in a mod or charger. The positive end is where the fireworks can occur.
The Wismec RX75s have a battery slot with the positive connection button spring loaded that is a little hard for me to get in and out.

I already guessed the punchline. I am just about ready to go into maintenance mode for my Kayfuns.Yeap, I had done everything correct the coil was cleaned and the "what the heck"??? After putting in some KJD it works just fine...![]()
I did a couple yesterday. I have 5 set up & teady to go. When I get a couple that have been used, I get them done & ready to go again. That way if something is going on & I can't get to it I'm not in a bind.I already guessed the punchline. I am just about ready to go into maintenance mode for my Kayfuns.
I had a question for you guys and gals do you think thinner wire gunks up less then thicker.
Gee those are kinda purdy. Isn't it amazing what you find when you start cleaning stuff out. I found a brand new package of cartomizers for the old carto tanks, these were the good one with 3 pinhead style holes in them. I filed them in the circular file. I still gotta get a bunch of stuff mailed off. I've got the boxes just need to address them but it was all I could do to make my honey bunny breakfast and lunch. I'm not used to having to go 3 days in a row and once I deliver her then gotta go shopping. At least tho I get stuff done while she is getting pumped full of poison that way the Friday I can kinda just kick back for a day. Will get stuff done tomorrow need to get packages mailed on Monday. Found a bunch of old atomizers I think they were called that you dropped juice on and put the long mouthpieces on I think that is how they worked. Pretty bad when you can't even remember how you used them. They look like maybe about a 25 caliber shell casing with cotton in them. Those were the days. Can't believe some of the ways we found to vape back then. No wonder I still smoked also. Geez that was over 9 years ago when I first started then found this place shortly thereafter. I had one of the old mini Provari's that didn't have variable power. I sold that to a guy that used to come here alot. Wonder how hes doin. I know some of the gals kept in touch with him but I forget his name now. Some of you old timers know who I mean, he had a cat which was pretty much his family.Well this is interesting. These have got to be the fanciest batteries and packaging I've ever seen; don't even remember getting them. Found them in a box of old random boxes and packing that I stashed in a back corner of the dining room when we cleaned out house last year, and the cats knocked it over.
