One of my batteries for my air 3s has decided to die and stop charging. I’ve reached out to DJI and they sent me a repair request link.
I put in the battery serial number, but it just brings up the 3s on the form. I detailed the issue was only one battery but at the bottom of the page it recommends I send back the “complete set of the product”.
Does this mean they want everything included in the fly more combo, or just the controller, drone and batteries/charger? Everything but one battery works perfectly fine so I’m a bit surprised they want more than that
Also does anyone know how long the process is likely to take? I have a few flights planned now that the weather is good and I don’t want to be without the drone for long
I’d call them up & explain, they don’t ( to the best of my knowledge ) usually ask you to return faulty batteries ( more so if there swelling up tho ) so I maybe wrong, usual process when battery is faulty or swollen is, they get you to do a video of you submerging the battery into a bucket of salt water submit the video to them then they replace if under warranty,
Was this through live chat ? However id still give them a call just to double check on what you mentioned above.
Gave them a ring and they said to just send the battery itself back, so I’ll package it up and get it sent. Glad I don’t need to be without the drone!
Cheers for the advice @PitchFader
Edit: they’ve sent a DPD label for it but DPD apparently won’t ship batteries according to their site
Glad you got it sorted bud 
Ooooops edit just see the DPD bit 
Have you asked them if you can do the saltwater video thing ? Or I’m guessing they may want to test it 
Or just send it as they’ve informed you
They sent me 5 last week from HobbyRC
I think new and unused batteries are fine from a shop/manufacturer, but if you’re posting them yourself it says prohibited here: DPD | Prohibited Items | Post Office
You aren’t the one posting. DJI are posting it to themselves. 
Hair-splitting - but perhaps that makes a difference.
As an update, I spoke to DJI again and they sent a UPS label, they say the battery is currently being repaired so I’ll hopefully have it back soon
