Guess I missed the long-term part. I was just referring to storage for the average (maybe every year) tube-roller.
No, obviously you wouldn't want to keep your tubes near a charging battery. I don't want an active battery-charger inside the house, for that matter, tubes or no, although I guess the LiOh batts in an iPhone kick out a bit of nastiness.
I would think that ambient moisture would be of more immediate concern. The exposed metals in a tube are susceptible to oxidation, sulfidation and God knows what else.
I'd like, out of idle curiosity, know the physics of the threat pure hydrogen poses. A charging battery emits H2S04, correct me if I'm wrong. I'd be more worried about the sulphur.
Charging a lead-acid battery emits hydrogen and oxygen. If overcharging some h2so4 will
be carried with the gases, this is commonly seen on top of lead-acid batteries and
will cause harmful effects on battery poles.
Yes moisture will affect pins and metal parts in a bad way. Corrosion under a
plate-cap or around any connections that cross the glass might harm the glass and
cause leakage, thus a dry environment is good. This will also save the carton boxes.
octal tubes ( or anything that is soldered) will affect any remnants of resin, also causing corrosion.
But again, most of these effects will be damaging in the long-term.
Oh, i forgot, the effect of hydrogen ( and helium ) :
it's small molecules, small enough to penetrate glass and especially the spaces
between leads and glass. Helium is smallest, hydrogen next. Filling the tube
with even small amounts of helium may cause flash-over since a portion of the
space will be hydrogen ions ( atoms stripped of electrons), they will be
attracted by the cathode and slowly hammer it's surface so to speak. In the worst
case they will even cause flash-over, which often is deadly ( for tubes).
