Storing batteries in the refrigerator: Myth versus fact.
So, should you? The answer from battery makers is a uniform and unequivocal.
"That's a long-held myth, and the answer is no," says Tom Van Voy of Panasonic Energy Corp. of America.
All the major brands recommend a clean, dry, room-temperature environment.
When stored properly, the discharge rate of a single-use alkaline battery, the most common type in the U.S., is negligible – only about 3% per year. Single-use lithium batteries lose even less.
Should I store batteries in the refrigerator or freezer?
In short: no. While cold environments help maintain battery life, refrigerators and freezers are not safe to put batteries in. The moist environment will cause condensation on the batteries. This in turn will lead to rust or other damage. Avoid putting batteries under extreme temperatures at all times.
BU-702: How to Store Batteries – Battery University
There is virtually no self-discharge below about 4.0V at 20C (68F); storing at 3.7V yields amazing longevity for most Li-ion systems. Finding the exact 40–50 percent SoC level to store Li-ion is not that important. At 40 percent charge, most Li-ion has an OCV of 3.82V/cell at room temperature. To get the correct reading after a charge or discharge, rest the battery for 90 minutes before taking the reading. If this is not practical, overshoot the discharge voltage by 50mV or go 50mV higher on charge. This means discharging to 3.77V/cell or charging to 3.87V/cell at a C-rate of 1C or less. The rubber band effect will settle the voltage at roughly 3.82V.

It's also my understanding freezing can destroy your screens, cause them to fail.


Ahhh okay... good information.. :thumbs:

I'll change what I'm doing...

I can say I have a few internal battery mods that have been stored in a cool dark drawer, okok forgotten :D, that are greater than 6 years old that powered on, took a charge and work just fine with screens as bright as ever. istick minis, an itaste and a handful of pen-stick style batteries. All when tested were at about a 40% charge. Although I don't think 6 odd years unchecked is a good idea, ever, I feel like dark/dry/room temp is good for storage. I also store 18350, 18490, 18650 batteries this way with good success.

My husband has an affinity for the Renovo Zero so I bought him several and was being hopeful we could get him through 2 or 3 years on these and a couple other small pods that are similar, before we have to switch him over to small mods and RTA's... I'm figuring provari for that, since he likes those even though he thinks they seem big...But I just figured I'd keep him with the zero as long as possible.

Thanks for the pics. So, what I understand from this is after 5 yrs in storage with no use, almost good as new?
They've been out of production for a long, long time, so don't have a new one to compare to, but I'll say this: After five years in storage it's perfectly readable in any indoor lighting condition, whereas the one the one that's been powered up a lot really isn't except in very dim light.

Self-discharge during storage is not the criteria that matters with our Li-ion batteries. Capacity retention is, and cooler than room temperature is definitely beneficial when it comes to that. Battery University shows this here and my own data after one year corroborates that it does help. I'll have two years worth of data this summer.

As for condensation: Put your batteries in a zip-lock freezer bag along with a silica desiccant pouch and it won't be an issue.

Now would I store a whole mod with electronics and a screen that way? I'm not sure. Before I did, I'd certainly check the manual for the allowable storage temperature range.

see and this is what I thought.. that's why I was storing hubbies little pod batteries in the freezer (vacuum sealed with desiccant)

but that article threw me... now I'm just confused.. lol

Don't be. The only thing to be said against storage in the refrigerator is moisture, and you've got that totally covered if they're vacuum sealed with desiccant.

FWIW, the 18650 cells in my long-term fridge and freezer temp test are just in normal battery cases in a ziplock bag; no desiccant. Personally, I think issue with condensation is overblown. Can condensation form when you pull something cold out of the refrigerator or freezer into a warm, humid room? Sure, but it doesn't form at the steady temperature inside the fridge or freezer; if it did everything in there would be wet, and it isn't.

Well I don't know of any Chinese mods that have manuals that address such a thing. They barely address how to use the mod lol.

I threw all the mods for long term storage in vacuum sealed bags with desiccant because we live in a very wet/humid area (over 43" average precipitation a year according to the internet) but thought because his pods had internal batteries I'd put them in the freezer instead of just storage bins...

so back in the freezer they'll go then. I just want everything to last as long as possible.

You might be right about that. The only Chinese mods I've got are a couple of Vandy Vape SimpleEX that I bought for occasions when I don't want to put one any of my irreplaceable good mods at risk. The manual for 'em is in numerous languages but lacks actual specifications and doesn't have an acceptable storage temperature range. :facepalm:

To be fair, I doubt any non-Chinese mod has any long-term storage recommendations, either. The only USA-made mods I own were bought second hand (no manuals) but I doubt their manuals address longterm storage. In fact, I have never bought any electronics that address longterm storage. Longterm storage simply isn't something that "normal" people want to know about the electronics they buy, they buy them to use them in the present.

I would not call an average of less than one inch per week "very wet". :)

When the time comes to break them out of storage, make sure you let them come fully to room temperature before breaking your seal. This avoids condensation. Also, never, ever charge a li-ion battery that's too cold. Again, let it come fully to room temperature before charging.

Husqvarna BLI20 (20 18650 cells, 10S-2P, with a BMS):
• Store the battery and the battery charger in a dry, moisture-free and frost-free space.
• Store the battery where the temperature is between 5 C and 25 C and never in direct sunlight.

I expect to be using the same topper and mixing the same liquid for my all day vape. Maybe a different device will be added to the mix. I might dabble a bit more with subohm variations and squonking over the next five years, pulling a few things out of the stockpile. Should new information make it safer to adjust my style a bit, I'll probably come around to adjusting.

In the early days of vaping the quest was to find one's "sweet spot", a satisfying vape that would keep one off the smokes. I found that sweet spot and am sticking with it. Everything else is just for fun and variety.
Yeah, same.
