My battery has been used only 16 times and after a couple of weeks stored when I press the button only led #1 lights on. I tried to charge it and now it does not work, it only blinks led #1 16 times, then nothing for about 6 to 7 secs and then the cycle repeats. Would you say is dead or could it be "brought to life again"? Is there any fix to this ? Thanks.

It may depend on the state in was in the last time you used it. How much charge was in the battery prior to storing it?

Could you read the info of this battery on DJI GO 4 app? If only LED 1 flashes, the one far away from the power button, the battery might be broken. You can try to drain the battery out and then keep in charge again. I suggest sending the battery in if it still not works.

Das hatte ich gestern auch. Nach ca. 20 Minuten begann der Akku zu laden.

Thanks. About 20% battery, stored for 6 weeks.

Thanks. Wrote to DJI Tech Support and they confirmed is defective. Now I have to send it to them, thing is that the shipping cost from México (where I live) is almost as expensive as the cost of a new one.

EDIT: let the battery cool off for a while then try again.  if its the LED blinking rapidily closest to the power button then that means the battery is too warm/too hot to charge..

Leaving the battery at that low charge for that length of time is not good for the battery and will probably not work properly again. You might be able to get some charge into it but it will never be reliable. If you are going to leave your batteries sit for a few weeks put them at storage of about 50%.

Did you buy it from the local retailer? If yes, you can try to ask them for help.

Also, don't rely on the LEDs for accurate check of battery level. Mine were at 2 1/2 LEDs for 4 months but as soon as I started a charge it indicated dead.

Just bought my Mavic Pro - 2 days ago. Brand new, out of the box. I take it out of the box today, 50 minutes ago. Started to charge the remote control and battery. But hold on.... the battery is dead, led 1 blinks 16 times. Come on guys, really? What can be done? Any suggestion would be greatly appreciated.

I bought the drone three days ago and I had to discharge the batteries before transport it in the airplane. After the purchase I tested the drone using two batteries but I can't remember which one was not used, I think this problem came from factory, how to proceed?

I have sent it back and received another one. I was amazed to see that the new battery was not even packed. The Romanian seller just gave me a battery. I wonder if it really was new. It works now.

Hi. I would recommend observing the performance of the battery and kindly keep us posted in any case you need our help. Thank you.

How does DJI store the batteries before they sell them? Surely they don't make them as they get orders for them and stop? Then start making them when another order comes in? They have to have excess in storage waiting to be sold yes? How long did they sit? Did they charge them before storage or is the first charge when we buy them?

Had exactly the same thing today. Brand new Mavic Pro Fly More Combo. The battery that was in the drone won't charge, green light furthest from the power button flashes 16 times then goes off. The other 2 batteries that were stored separate in the box charge fine. Had to fight with the store before they said they would replace it. In iBox Bali, Indonesia, official re-seller of DJI products in Indonesia.

I just got the mavic pro with the fly more combo. This is some bs. The two batteries in the fly combo do the single led flash 16 times and nothing. Now to top off the crap cake the one that came with the drone has a "bad cell" according to the DJI Go 4 app. I just got all of this just to find out I cant even fly/test or play with the damn thing. All firmware is up to date. I let the batteries charge all night with the original charger and the charger hub. I honestly expected more considering how expensive the DJI name is..

So I got a DJI Mavic pro Platinium Fly More pack last year... living in Paris (France) it was impossible to fly in the city...
This year I finally got a break, and was planning on flying it in Georgia where I have some relatives.
So I packed my neat little drone with all its accessories in an extra suitcase, with wild dreams of flight paths and helix Quickshots.
All for nil, reading this thread I recon that  the smart-batteries have a shelf life and all three of them refused to charge, showing the dreaded 16 fast flashes
Tried contacting both DJI certified resellers in Tbilisi, and have not found any replacement batteries.
If anyone has some pointers, please let me know.. don't want to end up with a DJI don't fly at all pack...

Just received today via FedEx a brand new Mavic Pro 2 Fly More...3 batteries.  All 3 no good, 2 give the dreaded 16 quick flashes; the one that was installed in the drone wouldn't even do that, and no response when button pushed to check charge level. WTF?  A real disappointment to spend this money and have no ability to fly the a/c until the new batteries are received.  Luckily, purchased through a reputable seller (B&H) and they are expediting replacement.  DJI should be grateful that places like B&H clean up after their messes.

Just received  two new magic pro batteries and they both display the dreaded 16 led blink and won’t take charge. I am so disappointed in buying this premium product just to receive batteries that won’t take charge.
What is the story with this. It’s suppose to be intelligent flight batteries of a suppose to be premium product but then won’t even charge. Now I have to try and get this sorted. Can someone please let me know what to do and how to go about changing over this clearly faulty product and receive what I actually purchased. So over this.
