Tell me about it! I've had two high end (read expensive) mods die. I had to send them back to Germany to get them repaired under warranty. The return postage could have bought a couple-few Kroma's.
"They" say storing batteries should be done at about 3.7 volts. I don't have a way to charge batts to a 'given' level and I'm not about to keep checking them and then take them off the charger. So I store mine fully charged. I just recently read storing them at full charge diminishes only slightly the lifetime of the battery. I can live with that.
But do make sure you turn the mod 'off'. A lot of mods have a small drain on the batt at all times and after storing for anywhere from a couple weeks to a couple-few months the battery will drain below acceptable levels. It probably wouldn't hurt to check the batt level every 3 months of so, to make sure it's not draining even if turned off.
I actually had a batt vent in a stored Provari. I forgot to take it out or turn off the mod.I put it on the shelf for months. And, Provari's are one of the worst for draining a batt when just sitting around unused and not turned off.
The top batt is the one that vented. The entire inside of the mod was covered in a grey film.

But, I filled the Provari tube with alcohol, swished it around, dumped it out and let it dry and changed the spring in the end cap. Put a good battery into it, and it worked! Provari Strong!
