Storing batteries

[Flipper1]

I'm presently using V2 e-cigs, but this week purchased the sigelei Zmax V3, which I am anxiously awaiting. I'd like to keep my V2s as a backup. I believe their batteries are lithium-ion. Is there a good way to keep these batteries "alive" when they're not being used for extended periods? Should I charge them fully first or drain them completely? Store them in the fridge, or under my pillow...? I just want 'em to work when I reach for one in three months. Thanks.

"40% charged, 15 degrees C."

If they are standard 3.7 volt nominal batteries, then 3.65 volts is the measurement for 40%. Take the measurement 90 minutes after they come off the charger..

If you don't have a way to measure the voltage of your batts, you can vape them dry, then put them on the charger for about half as long ish as it normally takes to recharge them. This really will be "close enough" and you should be good to store them for upwards of a year.

Wrap them in paper towel, and put them in a ziplock bag. Add dry instant rice, and store in the fridge. The paper towel and rice will keep the moisture that you seal in with the batts from condensing directly on the batts, or pooling on the inside of the bag, thus preventing water damage.

Excellent advice IMO ^^^. Only wanted to add one thing. When you take them out of the fridge give them time to come to almost room temperature before you open the bag or you can get condensation on the batteries.

Good point. Almost forgot they'll be cold coming back out.

Also, if you want to keep them for extended periods, you should warm them up and recharge them to 40% every so often - they'll self discharge, and if they go too low, they're (chilled) toast.
