Don't buy batteries (for Mavic) unless you plan on using them soon.

I purchased a couple of extra batteries while they were on sale (DJI via amazon) last fall. I did not use them until recently and both of them "died" within a month or so... with different problems. Only 6 uses on one of them.

Since the warranty on the battery is only 6 months I am not able to replace them under warranty.

So.. my advise is in the subject of this post. Don't buy extra batteries unless you need them soon.

Or, alternatively, cycle them at least once a month in the charger to keep them alive indefinitely.

6 months shouldn't be a problem since they will automatically discharge to around 60% after 10 days, and sometime later hibernate.

Sorry I have to disagree with you there. Letting a battery sit for 6 months without monitoring its voltage is a recipe for disaster.

So I guess... dont buy mavic batteries that have been on the shelf for a while.

If you can help it. But if you do buy them, and they have at least 1-2 green lights on, or at least 20% charge, and then they recharge just fine, it might be ok.

That's valid for every battery.

They're probably cheaper now than what they were at the time of the sale too

That's just it. Battery shouldn't discharge further than 20% in 6 months. More likely 40-50%.
Assuming of course it was over that in the first place.
