So I only had one battery for my original Mavic Pro, and I just saw someone selling more on Facebook Marketplace. I’m thinking about picking up one or two, but I’m not sure what to look out for when buying used ones. Any advice?
First thing — are they real DJI batteries and never used? If they’re used, I’d be cautious unless they’ve been well taken care of. You’ll want to know when they were first activated and how many times they’ve been charged.

What exactly does ‘genuine unactivated’ mean?

That just means original DJI batteries that have never been used or activated before.

Got it. Unfortunately, these are used. The seller said they no longer have the drone and didn’t give me much more info.
@Val
Then just be careful. I might take a chance on something like that, but I know what to look for. Since you’re not sure, it’s better to bring someone who knows, or just skip it. Definitely don’t buy without seeing them in person.
@Ash
Yeah it’s Facebook so I’ll be meeting them in person anyway. The deal seemed okay. Just wish DJI still made them so we could buy fresh ones.

Totally get that.
If I were you, I’d ask the seller to charge them before you meet. Then when you’re there, put them in your drone and check each one in the app — you can see the battery cell health and number of charge cycles.
If they’re totally dead, I wouldn’t buy them.
When you go to check them out, make sure they’re not swollen. Bring your drone and charger to test them on the spot. Plug them in and see if they hold charge. Check how many cycles they have and try to find out how old they are.
There’s a way to wake up a dead battery, but honestly, don’t mess with that — if they don’t even start to charge, it means they probably weren’t stored properly. It’s a gamble, and the seller not knowing much about them could be a red flag. Be safe and meet in a public place just in case.
@Jody
Yeah, I asked and they said the batteries were used about 20 times. But they also said they haven’t touched them in a year or two, so I’m not too confident they were stored right. They claim it still holds charge though.
