What to do with extra batteries

[Riptide]

Since batteries are consumables and the future is uncertain, I've picked up a some extras for a few of my drones. For longevity purposes do you think it would be better to just include them in the current rotation so that I end up with even usage (cycles) among all I own, or would it be more advantageous to bring the new ones to storage capacity (40%-60%), put them in an air tight container with a few desiccant packets, and store them in the fridge until the ones I'm using become unusable? I'm leaning towards the first option, but wanted to get some feedback. Thanks

I don't know that it takes all that to keep them stored but I plan to use *all* batteries in a slow rotation cycle rather than try to squirrel away a set. If I have long term batteries for storage, they are packed away inside an unopened drone kit.

Unused, new ones are theoretically supposed to be in a long term hibernation state, sealed in a retail box, that should not require any maintenance, designed for long term storage, from the factory until sale and placed into service, which could be several years. Once charged and activated, they then require regular maintenance.

That’s good to know. I’m doing the rotation method with all my batteries. I have 12 batteries for my neos and three for each of my other drones. I’ve made a chart to track which ones need to be cycled according to # of charges. My oldest drone is the A2 and all 3 batteries still work great and are at least 4-5 years old, each with 70+ charges.

DON'T DO THAT!!!!! Your batteries will condensate in a fridge!. Just a cool space away from direct sunlight is fine.
Keep them at storage (60%) till day of flight...use them...Re-charge to 60 and store.
You also dont want an airtight container, You just need something like a "Li-Po Bag", or I like to use old army ammo containers.
If you use an ammo container make sure to remove the rubber "seal" from the lid...... You want your batteries to get at least a little air while stored.
NEVER store a fully charged or Fully depleted Battery in an airtight container!

What’s the best (for the health) level of discharge for the battery, before recharging to storage level’s of 60%? Does it matter? Is it ok just to discharge to 60% for storage or more important to go to 20-30% then recharge to 60% for storage until next use?

As long as you keep them as close to a storage charge as possible while not in use any way will work fine.
I don't have a "gauge" so I just charge up a bunch of USB devices with the "leftover" till the battery is almost gone, and then I charge them back to storage.

Post number three is the best solution.

This is very good to know. I haven't actually taken them out of the box yet so I'll just leave them unused and store them in the part of my house that is always 68F or cooler.
