It seems that it is not possible to buy any new Spark batteries any more. Can't find them anywhere. My batteries are still OK, I have used them 14-17 times each and they are three years old. I guess thay should last quite long if recharging them once in a while. When they are dead, not sure what do do with the Spark, perhaps sell if anyone has any batteries that still work.What can be the life expectancy of the batteries, probably the number of cycles will give that?

Hello there MikaelBe. Good day and thank you for reaching out. The charge cycle for the DJI Spark's intelligent flight battery should be less than 200 times. A warning message will pop up if the battery goes wrong. In addition, you may try check our DJI Where To Buy platform on this link ( https://www.dji.com/where-to-buy ) to see if the DJI Spark's intelligent flight batteries are available. Thank you and please be safe always.
