Hello,

I bought a Mavic Pro about a year ago and I have used it only few times. last time I used was about a month ago and today I was charging batteries as I was planning to fly it tomorrow, but my 2 battries are dead only one is running. One battery does not even light up and another one blinks but does not charge or power my drone.

What can I do guys? Is my battery useless now?

Thanks

Yes.yes they are.
Even if you managed to get a charge into them, the would soon fail.

You should fully charge and discharge the batteries at least once every three months though preferably monthly.

Batteries need extra care to not lose their capacity. The manual gives plenty of informations about it (been crazy enough to read it). If you still have it, I encourage you to take a look for the next ones you buy.

Hi, thanks for reaching DJI Forum, apologies for any troubles you are having with your batteries. May we ask when was the last firmware update you performed on your aircraft and the remote controller?

The last Time I used was about month ago and I updated my DJI that time but I have not updated my remote controller. I read somewhere that the battery should not be 100% if you leave it for a while so I had both of my all my batteries around 50% and now 2 batteries are dead only one working.

Not many people read the manual. They should just put a sticker on battery itself as it is very expensive.  Now I have to spend £80

And those people who don't read the manual shouldn't be surprised when things go wrong for them.
Why wouldn't you read the manual?

Ok, so this is another case of DJI wanting to push product to drive up their profits.

Sheesh, these things are supposed to be INTELLIGENT BATTERIES, whoever heard of having to discharge and charge a battery fully every three months (nowhere does it say one month like someone said), and it's practically the LAST sentence on the LAST page of their battery manual. As sneaky as it gets.

WHY don't these batteries do the full discharge themselves after 3 months of inactivity and alert you with an app alert or beeping that they need recharging is beyond me.

Thanks DJI, I can now drop 3 batteries in the next recycling landfill and had 2 crashes due the mavic force-landing without warning in mountain terrain due to "critically low voltage". analyzing the logs showed 1 of 3 cells with abnormally low voltage in each case. Only 30-40 discharges each!

Now building a discharging rig with two 50w 12v halogen lamps.

No thanks to DJI, and as you probably guessed I'm pi*sed.

The batteries are intelligent.   They discharge down to storage level after 10 days, but they can't connect themselves to a charger.  It is a good practice to charge them, along with your RC, on a monthly basis.  You don't need to make a discharge rig.  The batteries will discharge themselves.  Just connect them to the charger once a month until they are fully charged.  The battery will do the rest.
