Th
So
Sorry I have been busy and couldn't respond earlier. I didn't say you couldn't or shouldn't do a rewrap, I said "be careful". Yes, things can and have gone wrong, so NO its not 100% completely safe. As far as battery design and heating up, batteries are "cells" which by design heat from the the center out do to the speed of current (<-amps) generating the electrical DC power during the draw. There are way to many factors to go into details but this is in general. So, by heating the outside of the battery (during things like a rewrap) you can break down the internals of the battery, which can cause other issues. One, degraded capacity hence the reason for a CAP check; two, drastic increase of internal base RI (impedance/total resistance) of the battery change (which naturally occurs over time from recharging at a much slower rate); and three, venting a battery. Although venting/exploding a battery is unlikely to occur, does not mean it will not. Keep in mind there are proper tools design (not just a hair dryer) to perform this function of heat shrinking electrical components and batteries which deflect direct heat in other ways. These are just my opinions and I want people to be safe to eliminate someone from getting injured or worse (we have all seen pics of battery issues, we don't need another that will hurt the Vape community). **NOTE, Not everthing you see on youtube is correct or safe** My experience: 2 degrees, 20 years Air Force in electrical aviaton systems.
Ok, thanks JJJAYMAN. I will do the rewrap, as they are more dangerous in their current state, and it will be moving heat, less than the batteries get heated to in some of my mods. Some of my mods the Atty gets scorching, and travels down, and I get a TEMP HIGH warning, remove the atty it goes straight away, keep it connected it takes about a minute to cool down a bit.
I was thinking as it will be less heat than they are usually exposed to, it shouldn't be a problem.
BTW, when I said about your low post count it was not meant as an insult, I just did not know how much you knew about batteries/ electronics. I may type things that come across a bit wrong sometimes, this could be one of them. I am brain damaged, so tend to not think through properly before typing. It is not severe damage though, like I am safe enough to use a mech, just takes me a bit longer for things to sink in, and it affects decision making and actions E.G I will be quicker to anger, although I am getting better in that regard now.
Hope I didn't offend you in anyway, I find everyone to be a friendly bunch on here, hopefully myself included lol.
I just didn't know if you was a 15 year old who had heard from a friend it was unsafe, or like you said, an expert on electronics for 20 years.
Thanks for your advice
