...just felt you were advising that it would destroy batteries when I have never had that effect in the mods that a more secure contact is preferable to eliminating battery rattle, I do not feel IMO that there is enough to destroy the battery wrapping (a very few mods with super tight tolerances aside) that could cause that damage before the life of the battery was entirely diminished...
I feel you, we're on the same spectrum just at different points on it (e.g., a scaredy-cat). I didn't intend to imply it'd cause it. It's definitely a remote thing, just not non-zero, and a mod designed for sliding the battery up and down appears to be adding unnecessary risk for little to no gain.
Stranger things have happened than a sharp bit of grit getting into the tube and getting ground into the wrap over and over. While I agree the wraps aren't tissue paper, I've seen wraps get knicked coming off the charger, knicked on a sharp edge of a mod, etc. One guy had a small tear at the edge of the wrap, a small thing that could have started peeling backwards; he wasn't sure how he did it, but his nails were like claws.
I'm entirely willing to reevaluate, but it'd generally require:
1. Having the actual benefit of a sliding battery be quantified -- a vague "we think it means you have to clean the bottom contacts less" is, well, vague.
2. Deciding that the quantified benefit was worth the increased risk, even if it's small.
And while it's late and I have your ear, what about the positive end now? While it's true that the contact surfaces completing a circuit will ionize the air and overtime that'll cause the contacts to get less conductive, aren't they just shifting this to the positive contact and atomizer contact? It's entirely possible I'm missing something, but erp...
