Some mods are hard on battery wraps. IPV-5, I am talking to you.
But, I did want to say, I love IMRbatteries in general. Good pricing, great customer service, batts usually arrive fast and with free silicone carrying cases. On my last order, IMRBatteries threw in a few extra wraps for free. Oh, I know the wraps are cheap, but I love IMRbatteries giving the nod to battery safety. Their products are definitely genuine. They're an excellent vendor.
Once I realized battery safety, I started being far more careful with my batteries. With excellent results. All my new batteries look as good as the day I got them. To be fair, my steampunk nano tesla does regurgitate batteries with the greatest of ease, they just fall out letting gravity do the work. This is an excellent feature EXCEPT the Steampunk does have a bit of a wonky battery door. A silicone sleeve solved that issue, but only after a battery fell out while driving into my uncovered coffee cup. That was a situation I found needed to be remedied, and I had to clean and rewrap that battery (I know, right? But I fished it out of there very quickly and dried it off immediately.... Even with my nitecore 2 bay charger (the sleds aren't the smoothest thing of all time) I've found if I pay attention while inserting them (have developed the method of pulling them ALL the way down, letting the battery rest in the charger, then slowlllly releasing the sled) it's not really a problem at all. Prior to that time my son was always examining and freaking out about the state of my wraps. They weren't *terrible* but they weren't great, either. I am now far more careful with my batteries, and they last much longer before needing any attention.
