Storing batts for long term that aren't in use..

[Butters78]

Long term to as in a couple months or so. I've read that they are to be stored in cool temps of course and kept at like 40 percent. On our 4.2 batts what would that be? I'm bad at math but to me 40 percent of 4.2 is like 1.68 which doesn't make sense. A little help would be great.

Just bring 'em down to 3.2 and you will be fine.

Which happens to be where a Vamo or eVic happens to flash at you to say STOP!!

I would also suggest a storage case for the things, if you're not using some now.

It is 40% of the available charge not voltage. Battery should not go below 3.2v
I fully charge and check monthly. If they get low top up.

I use a lot of batteries for electric RC Aircraft. They are stored most of the year due to weather conditions.

You keep yours stored fully charged? I heard that decreases life from the battery university, have you seen that?

My provari does the same, thanks!

3.6-3.8V. It isnt critical. If the batteries are still in good health it will take many months for the voltage to drop below the safe threshold.

So that would be the 40?

Good times. I've been recently paying more attention to one mod over the others and don't want their batts to suffer in the long run heh. Every penny counts.

So does letting them drop below their "dead" point... If they go below the point of no return (whether it be from not charging it or not using it and letting it self-discharge), you won't be able to recharge it back up to it's former maximum capacity.

I read recently in a thread that since our batteries don't have a memory, then it would be perfectly ok to store for long periods as there is no memory to worry about. So charge away whenever u see fit etc.

Personally, I would store mine at almost full charge. Most of mine came to me in that fashion, and I know they've been sitting in a warehouse Somewhere.....
But then again, back when the Army was saying to store batteries in freezers, I didn't listen to that either.. And I didn't have to reorder for a bunch of soaked batteries that weren't warmed up properly afterwards..

Close enough to 40%. More like 40%-60%. Like I said, it isn't critical, just somewhere in the middle of the usable voltage scale will do fine. If you find yourself checking the voltage every few minutes as you vape to hit a specific voltage, you're putting way to much effort into it.

The article that told me to store at 40 percent was talking about the lithium ions and you are correct. There is no memory which is great because you can charge whenever you want.
