Small circular dent on negative contact, is this safe? Thanks in advance.
Pretty sure you meant to say when the internal resistance increases.My VTC 5a cells seem to last about 3 months before the internal resistance starts to drop to the point I notice it during use.
Are you sure it's a dent? I get little circular marks that I would characterize more as "scratches" than "dents" on my batteries, just from normal use. I don't think these are necessarily something to worry about, but if there's truly an indentation then that's a different story. Can you get a good picture of it?Thanks bwh79. I'm ...... cause this means I have 2 useless machina mods. It only took 2 days for my batteries to be ruined as well.
Probably some carbon deposits, or electrical arcing marks.Are you sure it's a dent? I get little circular marks that I would characterize more as "scratches" than "dents" on my batteries, just from normal use.
Wooops! Good catch. I apologize for that slip. As you caught, I meant to say increases, lol. Thanks guys!Pretty sure you meant to say when the internal resistance increases.
As batteries age, the internal resistance increases. I don't believe its possible for the IR to decrease.
Quick question - Has anyone had experience with denting of batteries in the mech mod they regularly use? If so, could you please post pics? I very much want to see.
