Battery hibernated?

[Peiper44]

Hi,
I got 3 batteries of DJI Air 1. Didn't use for 2 years since I bought Mavic 2 Pro. Yesterday, I was able to charge only one battery without any problem. When I stopped using my Air 1, my batteries were fully charged. Now, two of them are "dead". No red, green light, nothing. Batteries are not bloated at all. My charger jumps from port to port with info checking.
Any help? Any idea? Are my batteries done?
Thanx,

sadly it would appear that after 2 years of none use that the batteries have died,

Put them on charge for 4 - 6 hours one by one.
Don't use the hub if you have one, just plug directly into the charger without the hub.

Naa try to put them 3-4 days on charger and dont touch it.


I was able to revive a gopro karma drone battery dated 2016oktober05 in condition of what i believe never got a charge for 3-4 years.

Got it alive in 48 hours of just putting it in charger.

Offcourse. Gopro batteries are better quality.

I still hve my original gopro hero 1 camera released in 2009 and surprisingly after maybe 5 years of not even charging, its still took a charge last night.
